Ryan’s last day on the Rock

5 First Year and 2 Second Year students are finishing their project week today. Their service and enthusiasm was a fantastic component of my last week at Race Rocks. Alex Fletcher is staying on the island as he starts his shift. Best of luck to everyone at Pearson College and Race Rocks, thanks for these amazing 3 years! There were 10 visitors to the island today. (Ryan Murphy)

Unidentified Ectoproct photographed by Ryan Murphy

 An Ectoproct ( Bryozoa) that we have not yet been able to identify.

An Ectoproct ( Bryozoa) that we have not yet been able to identify. This image appeared originally on Ryan’s Flickr site in the picture of a shrimp at http://www.flickr.com/photos/ryanjmurphy/6351563627/in/photostream/

 

I was struck by the appearance of the background of the image, although the shrimp was certainly attractive. The name “Phoronid” came to mind , and we identified it as Phoronis vancouverensis however, I have since been informed by the experts that this is not the case.   So it remains an unknown species, possibly an Ectoproct  Bryozoan. We would appreciate hearing from anyone who may recognize the species.

Catrin and Bio class out

Northern Sea Lion count: 129.

The nursing pup is still here and is very vocal for most of the day. It is surprisingly spritely given the ungainly proportions of its flippers!

Erik, Catrin and her first year Biology class came today to for work on the u/w camera installation and study of populations and communities respectively. There were 16 visitors to the island today.
