Cucumaria miniata: Orange sea cucumber–The Race Rocks Taxonomy

The orange Cucumaria miniata sea cucumber is a common resident just off the docks at Race Rocks in 5 to 10 meters of water. In this video they occur in a high concentration relative to other areas. Each orange tuft is the tentacle mass. If disturbed, it quickly withdraws into the sea cucumber body which is always buried under loose rocks.

Note the name Cucumaria miniata should be on the following video instead of C. curata

General Description:The Orange sea cucumber received its Latin name, Cucumaria because it resembles a cucumber. The orange pigment that separates it from other sea cucumbers comes from a chemical called cinnabar or vermilion. Although it seems to be completely soft and fragile, it actually has bone-like plates in the body wall called ossicles. To stay attached to the holes between the rocks, the cucumber uses tube feet that you can see in the image above in 5 rows around the circumference of the body. If you ever want to keep one as a pet, don’t get too attached because they usually only live about 5 years, sometimes 10 if they’re lucky.

Habitat:

Sea cucumbers live in between boulders and sheltered rock formations. Because they are able to stay attached to surfaces, they prefer to live in areas with stronger currents, making it harder for predators to reach them.

Feeding:

The orange sea cucumber is a suspension feeder. This means that it catches food in its tentacles. After the food is caught, it removes the food with its eating arms and scrapes it into its mouth. Sea cucumbers eat plankton and detritus.

Reproduction:

Unfortunately, sea cucumbers aren’t very intimate creatures. In fact, their mating process can’t have any less contact. When the time comes to make a new cucumber and two cucumbers are physically (and emotionally) ready, one will release eggs into the water and the other will release sperm. From that, the two elements meet in suspension and that’s it.

Predators and Defenses:

The cucumbers main predators include fish, and even humans. That’s right kids, there are some people in the world that actually eat these things. To protect itself, the cucumber has many defenses. Their skin is some of the most amazing tissue found on an animal. The compound is made of a material called ‘catch collagen’ which can change from liquid to solid when neurologically triggered. It does this so can squeeze into small spaces and then harden again. Another defense is they “pee” out all the water in their system and shrink into a small, hard rock. The “peeing” usually occurs when the cucumber is removed from its habitat. If that’s not enough for you, they also can bust out a defense called evisceration. What happens here is if the cucumber is stressed and scared enough, it will spew its guts out. That means everything, intestines, gonads, respiratory organs, everything. Now after that, you would think that’s the end but if it can get itself to a safe habitat, it can actually regenerate its organs.

Biotic Associations

These guys are generally really passive, and they don’t really interact with any other organism or with between each other really.

Metridium farcimen: Giant Plumose Anemone–The Race Rocks Taxonomy

General description: The Giant Plumose Anemone is a fairly large anemone of typically white, cream, tan, orange or brown colourations. Subtidal animals can often reach 25cm in crown diameter and 50cm in height. However larger specimens have been reported around 75cm in height. Shape of the column is much longer than wide. Tentacles lining the mouth of the oral disk are quite fine, very numerous, slender and short. Tentacle colouration is typically transparent when the tentacles are expanded and take the colour of the column when contracted.Habitat: Found in both subtidal and low intertidal zones, including jetties, wharfs, harbours, breakwaters and floats. When found on wharfs, anemone communities of dense distribution are common. Larger specimens are often found solitarily in the subtidal. The Plumose Anemone ranges from Alaska to southern California and along both sides of America.

These images by Ryan Murphy show the biological associations of which they are a part.

 

Feeding: Both the small and large anemones feed primarily on zooplankton, using their stinging tentacles to catch the prey. The feeding appears non-selective. Scraps of fish and squid and small benthic (subtidal) organisms are also taken.

In this video Ben from Australia introduces us to this abundant anemone found in the waters around Race Rocks. Note the fine tentacles– ideal for trapping plankton in the high current areas. Also note that this is not Metridium senile as labelled, but Metridium farcimen 

Predators: The Plumose Anemone has few predators. Nudibranchs feed on small anemone, while in Puget Sound (Washington State) a sea star (Dermasterias imbricata) has been found to feed on larger anemones.

Reproduction: The anemone reproduces both asexually and sexually. Asexual reproduction occurs as the anemone moves about, leaving small sections of its pedal disk (base) behind, in a process described as pedal laceration. Dense colonies can be formed in this manner, with the pedal disks forming small cloned rounded anemones that feed and grow.

Sexual reproduction occurs in a broadcast spawning process whereby the males release sperm with wedged-shaped heads stimulating the females to release their eggs, about 0.1mm in diameter with a pinkish colouration. External fertilization occurs, with the zygote dividing to form a planula larva which swims in planktonic form. Adam Harding caught this process in action in July .

 Planulae settle and metamorphose into young anemones.

Biotic Associations: Plumose Anemone symbiosis is an area in which little research has been done. Possible commensal behaviour may be similar to other anemones which have certain fish (e.g Clown Fish) which use the anemone.

Interesting behaviour: Anemones are rich in nematocysts (stinging cells) which are used in both defense and attack. The normal tentacles contain these cells used for both defense and feeding. However, in large colonies of Plumose Anemones the species bordering the colony develop a different type of tentacle; “catch” tentacles. These tentacles, which are used to repel non-cloned anemones, take about 9 weeks to develop close to the mouth and may number as great as 19 on an individual organism. If the “catch” tentacles, which contain a different type of nematocysts, touch another anenome from a separate colony a stinging tip breaks of and releases the separate complement of nematocysts. This technique is used to repel intruding anemones. Interestingly, these tentacles can expand to a possible length of 12cm.

A Biography of Tom Sampson

We were fortunate to have Tom Sampson on the Race Rocks Marine Protected Area Advisory Board in 2000-2002. Tom brought to the board a welcome First Nations perspective . His concept of the three-legged milk-stool model of governance for the MPA was whole-heartedly accepted by the advisory group  and formed our basis for recommedation to DFO for MPA status.

tom_ministers

In his model, where the Provincial,Federal and First Nations governments formed the legs of the stool which supported the seat which was composed of the stake-holders and the marine ecosystems of the area . Unfortunately when the proposal went to Ottawa this model was not accepted, leading to a breakdown of the MPA process.

The article below appeared in a Georgia Strait Alliance newsletter:
Outgoing GSA  (Georgia Strait Alliance) director Tom Sampson has lived all his life on the shores of Saanich Inlet. His family’s tradition is that the first born always goes to the grandparents—a way of ensuring that the new generation gets a solid grounding in traditional knowledge. As the eldest of 12 children, Tom was raised by his great grandmother, a remarkable Halalt woman who had raised his father before him.

 

He describes her as “the lady who taught me everything”. In her 80’s when two-year-old Tom came to live with her, she taught him history, his place in the world, spiritual beliefs and all about the natural world, in both languages of the Coast Salish, her own Halkomelem (Cowichan) and her husband’s Sencoten (Saanich). No one knew her exact age, but baptismal records showed she was over 120 when she died about 30 years ago.

Tom became immersed in the English language when he started school. Fortunately his great grandmother refused to let the church take him away to residential school, though five of his siblings weren’t so lucky. Tom did well at Indian Day School, and qualified for an academic program at St. Louis College in Victoria, where he attended grades 10 and 11. He enjoyed school and excelled in math and languages, learning to speak French and Latin on top of his other three languages. But it was a hard time for his family economically, so he quit and went to work in the woods as a whistle-punk.

It was a time of rapid change and development of resource industries. Yet already the problems were starting to show, if one paid attention: the trees being cut were significantly smaller than those Tom’s father had cut during his time as a logger.

Tom describes the devastation of resources that he has seen over his 64 years and how this has led to “a crisis all across North America”. He remembers, as a young man, regularly building fires on the beach to steam clams and mussels. Today, he says, that’s not possible, “because our beaches have been destroyed”.

“We seem to have the attitude,” he says, “that we need to destroy what doesn’t pay off monetary value of some kind—that it has no value and should be terminated. Scientists, managers and technicians seem to believe they know more about the environment than our people.”

He describes predictions that his people have made for decades about salmon, herring and other resources —that unless these were managed in a different way they would disappear. He quotes Chief Seattle and other tribal leaders over the past 50 years, but says they were always ignored by government officials. “We don’t have the degrees and diplomas, so our information isn’t considered important,” he says. “Yet our total survival has been based on understanding nature.”

“Our concept of harvesting of the land and ocean are based on the 13 moons of the year—the absolute time clock of nature, ” he explains. “We managed our resources by understanding this clock, which meant there was a right time for everything, and a time we weren’t allowed to harvest.” Tom has organized sessions on the 13-moon concept as part of his work on the Race Rocks marine protected area, where he has worked to improve cross-cultural understanding and appreciation for the traditional knowledge his people bring to the table. “It’s important that people understand that when we talk about the land we’re talking about a relationship that goes back thousands of years,” he says. “We know this land better than anybody else.”

This focus on cross-cultural awareness has been evident in other environmental work that Tom has tackled. A few years ago he played a key role in getting the BC Environmental Assessment Office to undertake a ground-breaking Aboriginal Land Uses Study within the Bamberton Environmental Assessment, which documented traditional knowledge from elders and others from the Saanich tribes; it was done in the traditional language and then translated into English.

Tom believes that listening is the key to understanding the environment. He remembers his great grandmother telling him to go down to the beach and listen to the ocean, because “if you don’t listen to it and hear the stories, you won’t learn”. Listening to each other is just as important to Tom, and he believes this skill is not being taught to most young people today.

Tom has taken a leadership role for most of his adult life. He’s been involved in tribal politics right to the national level, serving as Chief of Tsartlip for 24 years, chairman of the South Island Tribal Council for 22 years, vice-chief of the BC Assembly of First Nations, chairman of the Assembly’s Constitutional Working Group for Status Indians and chair of the Douglas Treaty Council.

Although “retired” from tribal politics, Tom has certainly not slowed down. The schedule of long days that he keeps as a volunteer would exhaust most people half his age. He works tirelessly, helping people that the system has failed.

One of his key concerns is how the justice system has been unfair to aboriginal people and ignored their beliefs about individual and community healing. “The system works if you can afford it,” he says, pointing out that from 60 to 90% of his people live in poverty. It is this poverty that has motivated Tom to work for his people.

Another area of his volunteer work is community health. He’s working more with older people these days, since the average age of his people has risen (though it’s still only 55). But he says his tribe has to struggle against the legacy of the 40-year-long residential school experience, which destroyed the social fabric of many families, removing positive family models and leading to many of the social problems experienced by native communities today.

But there’s been no shortage of strong models in Tom’s family. He remembers his mother, a Nez Perce from Idaho, serving on the Tsartlip council at “a strange time” when the band elected an all-woman council (one of the first in his territory) with a man as chief.

Tom’s wife of 43 years, Audrey—as active as Tom in community work and a vocal advocate of aboriginal rights—also comes from a family of strong models. Her father was a Cowichan chief and tribal spokesman for many years, and like Tom, her mother served on the band council. Audrey has served on the Tsartlip council, and now works as coordinator for adult health care for all the Saanich First Nations. Tom is visibly proud of Audrey and impressed with her ability to juggle her roles as mother, grandmother, great grandmother, housewife and full-time health administrator.

But he’s no slacker himself! On top of his community-based work, these days he’s very busy building the new Coast Salish Sea Council, an initiative he launched to bring together the close to 90 Coast Salish tribes on both sides of the Canada-US border, to develop agreements and move forward on social and environmental issues. Later this month the Lummi tribe will host the first major meeting of the Council, and Tom is busy organizing this.

He’s also doing a lot of traveling—recently to Seattle, Ottawa, and Texas, speaking out on environmental issues and urging that action accompany agreements.

When he gets time at home he loves to garden, a skill he learned from his father who taught him that, “when you run out of money at least you’ll have food”. This year he has planted a full acre with flowers and vegetables. He also spends as much time as possible with his five children, 10 grandchildren and one great grandchild, who all live close by. He thanks his great grandmother for teaching him the importance of “never losing” his family.

Tom says he has learned a lot from his first year with GSA and he plans to stay involved even though he will no longer be on the Board. One thing that’s made a big difference is learning to use a computer (something he had to do over the past year as a Director). Being “wired” has provided him with daily information from all over the world, which Tom says has “helped me understand issues, linkages and the reasons behind things.” He sees modern communication skills as vital for young people.

But spiritual beliefs form the heart of his environmental philosophy. “Conservation and management of resources are inseparable from these,” he says. “If you don’t see the spiritual need for the land and water, then people will continue to dump raw sewage, log mountains, and devastate the streams beyond repair. We have to look at ourselves. We can’t be holistic without a spiritual connection to the land.”

Psolus chitonoides: creeping pedal sea cucumber

Predation of a Psolus chitinoides by a sea star is examined and discussed by Laura and Nadege. The stomach of the sea star surrounds the sea cucumber and the soft neck and mouth of Psolus is well inside the cavity of the sea

 

Sea cucumbers have inhabited the world’ s oceans for about 400 million years. Psolus chitonoides is an unusual species of these marine invertebrates. Its diverse characteristics have given it 4 common names: Armoured sea cucumber, Creeping armoured sea cucumber, Slipper sea cucumber and Creeping pedal sea cucumber.

Compare the tentaclesof Psolus with the end of the California Sea Cucumber to the left. Photo by Dr.A.Svoboda

Tentacles of P.chitinoides

A-Description

As all echinoderms, the creeping pedal cucumber has a spiny skin. Also, its appearance is closer to a chiton than to a sea cucumber (here is the origin of its name “chitonoides“).

1-External features:an oval body (7cm long to 5.8 cm wide) domed dorsally with stiff, shingle-like scales, flat, flexible sole ventrally. Its tentacles(8-10) are dendritic, equal in size, or 8 large and 2 small. Also observing the body, it could be compared to an elongate cylinder lying on its side with the mouth at one end and the anus at the other. The rows of tube feet run the length of the body

2-Internal features: the tentacle ampullae, the rete mirable and cuverian organs are absent . On the other hand, we can observe the presence of retractor muscles. Respiratory trees are “y shaped”. Note that its madreporic body is attached to a dorsal mesentery. Its internal calcareous skeleton is composed as following:calcareous ring with anterior processes only. Psolus chitonoides is characterized by typical skin ossicles, where one type of circular perforated plate (some with knobs coalesced into a raised network) occur only in the ventral sole.

Phylum Echinodermata
Class Holothuroidea
SubclassAspidochirotacea
Order Dendrochirotida
Family Psolidae
Genus Psolus
Species chitonoides

Common Name: Creeping pedal sea cucumber
B-Physiology and Biology

1-Suspension feeder: tentacles trap larger particles (larger than 2mm) by bending inwards to form a cagelike enclosure. The mouth lips extend toward the particle as the nearest tentacle pushes it into the mouth .

2-Reproduction : the reproductive organs of a sea cucumber generally consist of 1 or 2 tufts of elongated tubules in the forepart of the body cavity.Spawning occurs annually, from mid March ot late May, commonly in the early morning. A spawning male will swab its genital papilla with its tentacles, then lift the tentacles to disperse the sperm . Females release long ropes of brick red eggs; fertilized eggs develop into pelagic lecithotrophic vitellaria larvae. Late larvae and early juveniles are negatively phototatic and settle gregariously.

3- Respiratory system: its water vascular system is a hydraulic system made up of tubes and valves that operate rows of extendible tube feet . As other sea cucumbers, Slipper sea cucumbers respire through their tube feet, body wall and respiratory trees.

4-Chemicals: there are toxic chemicals (saponins) on its tentacles, discouraging predators from nipping the tentacles. For example, even the Kelp Greenling (Hexagrammos decagrammus), which feeds on sea cucumbers, avoids this species.

C-Predators, parasites and commensals

1-Sea stars and fish are the main predators of the Psolus chitonoides.

2-Parasitic forms of flatworms and snails can live inside the sea cucumber

3-Commensal organisms are mostly scales that mimic the colour of sea cucumbers, and crawl on their skin.

D-Habitat

From exposed coast to sheltered inlets; although it seems to prefer clean, vertical rock that is free of sediment. Its soft, flat sole enables it to attach firmly to rock.

E-Range

Aleutian Islands to Baja California ; intertidal to 247m ; common in shallow subtidal areas.

Solaster dawsoni :Morning Sun star– The Race Rocks Taxonomy

Description

Solaster dawsoni, named after its finder is an eight to sixteen armed starfish. Ranging from grey, yellow, brown or red with light patches covering the upper surface of its body, this sea star looks very much like a “sun”. It can grow up to a radius of 25cm (10″) with the central disk in between the arms a third of its total radius. It has radial symmetry and an endoskeleton like most other starfish and again, uses the normal water vascular system. It moves around on tube feet and therefore is a very slow moving animal. It breaths through skin gills.

Habitat

Solaster dawsoni resides in the cold, rocky intertidal and subtidal costal waters of the west coast of America, ranging from Alaska right down to California. It lives on a variety of bottom types, and can survive from the low tide line to around 420 metres (1200 feet) deep.

Feeding

Solaster dawsoni, unlike other species, preys on other sea stars. It is the “feared” predator of the orange cucumber and other starfish have been known to flee when touched by it. It will even prey on its own kind including its very close relative Solaster stimpsoni. This sea star also eats sea cucumbers and diamondback nudibranchs. Solaster dawsoni has to either overlap or grasp its prey before it can secure it and because of its slowness this may be the only way it can catch its prey. Because of sea stars’ “blindness”, a large sea star will sometimes flee when touched by a small one. In this way, Solaster dawsoni has been known to kill larger sea stars than itself.

ReproductionThe sun star spawns in the period of March to June when the ovaries contain the full sized oocytes (eggs). It releases large yolky eggs which float to the surface, where they are fertilized and develop into pelagic non-feeding larvae which are also buoyant. At this stage the larvae can not feed but can swim around. From here they then develop into sea stars.Defences and PredatorsAs the most fearsome of all the starfish, Solaster dawsoni is almost completely safe in the water. As mentioned already, one of this sea stars only predators is in fact, its own species.Biotic interactionSolaster dawsoni is a very passive organism. Living on its own, the only interactions it has are with its prey. Also during reproduction, the male and female are much closer together.

Webcasting from Under the Race Rocks Waves Direct to an Educational Conference in Hollywood

LIVE AND QUICK IN THE RACE:

WEBCASTING FROM UNDER THE RACE ROCKS WAVES DIRECT TO AN EDUCATIONAL CONFERENCE IN HOLLYWOOD

February 21, 2002. number 13.

Garry Fletcher and the webcasting activity group

On Thursday, Feb 14, several members of our racerocks.com activity group escaped mid-morning to Race Rocks to participate in a live webcast to the QuickTime Live conference in Hollywood, California. You could say they were “on stage Live in Hollywood!” Well , , , almost !

Chris, Damien and Nigel braved an ebb current off the dock to perform for the webcast from underwater . They developed a new technique of hooking themselves to a guide line to ensure we could get out live some good examples of underwater life at Race Rocks, even though the conditions were less than ideal. Garry, Monica, Olend and Kiprop manipulated images and video streams on the webcasting computer top side while they did a test drive of the new webcasting software called “Live Channel.”

“The exciting thing for us” said the students “was that we were able to make smooth transitions between the underwater camera and the camera on the docks while also inserting selected pre-recorded clips and still images.”

“The purpose of this exercise,” added Garry Fletcher, “was to demonstrate to our audience at the conference in California how we can use the technology of racerocks.com in a wide variety of educational applications.”

It was only a week earlier that the decision had been made by the group to go with the amazing, yet so far unproven webcasting software “LiveChannel”. A new partner, “Channel Storm”, a software company from Israel, has been impressed with our work with the live cameras and the Race Rocks web site and has offered to partner with us by providing their software. They came through with last minute advice by long distance and many reassuring e-mails from their software engineers. Further links with our co- presenter from the Apple Learning Interchange, the generous provider of the services of the Akamai network for our video distribution on the internet made all this possible.

“I think our students are beginning to realize what an incredibly unique opportunity they have to pioneer in this area. It just has such a great potential for many educational applications.” continued Garry. “We even use the International Affairs presentations each week with the two cameras to practise some aspects of webcasting and on- the fly editing. Those students who really wish to take advantage of it are able to gain experience with some real cutting edge technology.” The racerocks.com activity is adding a webpage this week to provide images of the venture.

A recent addition to the campus side of racerocks.com is a wireless aerial atop the academic building, just like that used at Race Rocks. This gives an added opportunity to cover wirelessly events from around the college campus, outdoors or in. As spring approaches, watch for notices on the webcast schedule page on the Pearson homepage for short-notice of events.
