Slash and Sleep Apnea
Slash the elephant seal male was having a good sleep in the morning behind the boathouse.
I took this video clip of our resident elephant seal “Slash” asleep in one of his favourite spots behind the boathouse at Race Rocks. At 8:00 am he was in a deep sleep, interrupted only by the kelp flies on his face and a few itchy spots on his body. What was remarkable was the recurring pattern of breath holding. I made this video as a study of this aspect of what appears to be intentional sleep apnea. Since the filming was uninterrupted, one can time the various phases of a breathing cycle. Labels on the video point out the beginning and end of one such breath-holding cycle. I observed that he repeated a similar pattern for at least 15 minutes, the length of time I as was able to observe. GF.
Listen for the sounds and watch for the flaring nostrils.

whale watching boat
West Coast Wildlife Adventures approached to view the elephant seal within 10 meters of the seal. I advised him he was too close since slash was there basking in the water. He had moved in to get a close look from a few metres. Images placed on ecotourism page on web. This is not the first whale watching boat that is coming in too close this season. With seal pups in the water this is a dangerous thing to do. See the ecotourism page for more information.’, ‘Garry’, ’12:41:23′),
Purple Sea Stars – Rare occurence at Race Rocks
I found another black oystercatcher nest down in front of the Winch House, so moved camera 3 over to it. (Update note on July 17–2 young were observed near the nest). In the morning I went out on the intertidal for the minus tide. Excellent long exposure of the surge channel and the cave on the South west side. Also got onto Anita”s intertidal island down from the helipad on the west islet which becomes a penninsula at low tide.
I was looking for the large (45 cm diameter Purple star. Which I saw there two years ago, and at that time I thought he was the only one on the island. This time I found another smaller one– 30 cm diameter in a similar protected channel only 2 metres from the other one. Since these sea stars inhabit the lower intertidal zone, they cannot withstand the heavy wave action that occurs in that area without these deep channels which are protected by a rise on the seaward side to the west. As far as I know these are the only two purple stars occurring at Race Rocks. They are very common however in other sheltered inland coastlines in BC and are frequently the first sea star that visitors to BC shores notice. I also made note of a large number of very colourful brooding anemone exposed on the same protected mussel-covered wall on that island. There was an unusual abundance of blue ones which I remember to be rather rare when seen by diving in that area previously . One gull nest close to the science centre has chicks hatching.’, ‘Garry’, ’09:59:49

June July 2008-slash moulting
June 12, 2008: Erik and Garry checked out and photographed the reported entangled elephant seal on Middle Rock. File opened at http://www.racerocks.com/racerock/eco/taxalab/miroungaa/roped.htm
June 17, 2008 One elephant seal on Middle island, and Slash, our favourite old elephant seal hauled out on Great Race again this morning, but he had moved over to middle island in the afternoon. The entangled one we saw last week was not around this afternoon.

July 21 2008. Slash on Great Race behind boathouse.
July 23, 2008: Elephant seal changed location; now behind boat house.
Slash spent from 5:00PM to 8:00 PM in the sea, otherwise up behind boathouse. ( preset 1 on cam 1) He has 3/4 of his old hair moulted off, new light gray color beneath. The old hair was light brown.
July 24, 2008 Slash moved down again to the shade of the Workshop as it is very hot at noon.
July 25, 2008 Slash now moved up to his spot on the lawn west of the Science house. (Can be seen on camera2)
One other male elephant seal and one smaller female remain out on the Middle rock.
