bryozoa

Photo by Dr. Anita Brinckmann-Voss

This species is classified in The Lophophorate Phyla of British Columbia: Entoprocts,Bryozoans,Phoronids and Brachiopods by Aaron Baldwin School of Fisheries, U. of Alaska.

We see this bryozoan frequently in the lower intertidal while diving at Race Rocks in 8-12 metres of water.

“Each colony is hte result of budding or cloning from the original individual itself having developed from a planktonic larvae that settled … In the case of this species, the process is programmed as a spiral growth pattern. From ” Marine Life of the Pacific Northwest, Andy Lamb and Bernard P. Hanby ,2005,

Stylasterias forreri: Fish-eating star or Velcro seastar–The Race Rocks taxonomy

This photo taken by Andrew McCurdy in August 2010 is from West Race Rocks around 40ft depth. It is not a very common sea star out there..

From Wikipedia: The velcro star feeds on invertebrates such as gastropod molluscs and chitons. When alert to movement in the water nearby, the rings of pedicellariae are extended, ready for action. If anything touches its aboral (upper) surface, the starfish reacts by snapping shut the pedicellariae in the vicinity of the stimulus. By this means it can catch prey items such as small fish.[3] The victim is passed to the mouth by movements of the arms and by actions of the tube feet. The velcro star can also defend itself against attack by predators such as the voracious morning sun star (Solaster dawsoni).[3] To fight back, it coils its arms around the attacker and inflicts thousands of nips with its pedicellariae. The attacker often retreats and the velcro star escapes.[3]

>> I have three more brands to report today (I saw at least two more but couldn’t get a good visual on them unfortunately):
>>
>> #984, a California. At first glance, this one appears to be #934, but it’s definitely an 8 when you get a good look at it.
>>
>> #1052, a California.
>>
>> #1032, a California.
>>
>> All were spotted hauled up on the NE corner of Great Race. See attached photos. Again, any information you can provide about these individuals is greatly appreciated.
>> Thanks a lot!

14Y BRANDED SEALION

Pat Gearin responded: ” Hello Adam and thank you for reporting this sighting and for sending the excellent photos.  This animal is Steller sea lion 14Y, an 8-year old male marked at St. George Reef, CA in July of 2002 as a pup.  This is a valuable sighting since he has only been sighted 4 times since he was marked including once at St. George Reef a month or so after his initial marking.  He was sighted again in May 2005 at Tatoosh Island, WA.  The most recent sightings were from August 2008 when he was sighted twice off SW Vancouver Island at Barrier Rocks and Pachena Point.  This animal is not yet of breeding age/size but may be in a few years. Thanks once again and we look forward to any other sea lion sightings you can provide. ”

 

Sealions return

Hello all, I realise that it has been a little while since I last wrote in the daily log. Things have been busy. Ocean Educations, a three week summer diving program at Pearson College just finished this week and I’ve been busy with that, as well as keeping a German film crew of four from German public TV busy -you may have noticed Tom, Christian, Florian and Michael on the Island this week). They were busy shooting two documentaries at Race Rocks. They left this morning and I’m pleased to say that they acquired some stunning footage, above and below the water, during their stay. Things have quieted down a bit now though, so I hope to be a bit more regular in my entries for these last few weeks of my stationing at Race. Many of you will be pleased to hear that camera 5 has been repaired. Apparently there was a problem in the electrical board inside. I have it on the Island and am planning on re-installing on its mount tomorrow. If all goes to plan, it should be up and running by tomorrow afternoon. Over the last week or so, the sea lions have made quite a return. I ‘d estimate that there are probably around 100 individuals in the Reserve right now, with an equal split between northern sea lions and California sea lions. Their numbers will continue to grow as the summer draws slowly to a close. Slash is still hauled up on Great Race these days, as always. I’ve not seen Misery for a while now, although it ”s possible he’s out on Middle Rock as I saw a couple of elephant seals out there a few days ago. I suspect that Misery got a bit sick of Slash and decided to seek out some peace and quiet. There was also a mature female here for a few days late last week and early this week, but she has since left. The gull chicks are now getting quite large. Many have started to fledge and are beginning to ”test their wings ”. I ‘ve not seen any in the air yet, although I ”ve seen many flapping their limbs energetically as they try to see how their wings work! This week I also found quite a large number of dead and/or injured chicks. I think they are often attacked by other adults from outside their territory. There is actually a chick right outside my basement door that has been there for four days now; my best guess is that it wandered or ran off far from the nest then couldn ‘t find its way back. On the third day -yesterday), I woke up to find it with a broken wing. It ”s quite sad to see it huddling in the damp grass with a broken wing, while a couple of metres away, a mother feeds her three healthy chicks. Quite a stark division. I expect this chick will soon die from starvation or predation. I saw the otter several times this week. I haven ”t seen as many eagles around this week as I have in previous weeks. I ”ll keep you updated to this poor little gull over the next few days. That ”s all for now. Adam’, ’21:20:54 ,
