Marine animal agglomeration

During my volunteer docent shift at the Seymour Marine Discovery Center last week, I took pictures of the marine life. Enjoy!


Sea urchin Strongylocentrotus purpuratus. 
The white dot in the center is its five-toothed 
mouth called Aristotle's lantern.

Sea hare Aplysia californica (rear view) with sea cucumber 
in the background. The sea hare can release a dark purple 
ink as a defense. Click here to see a video of this sea hare in 
motion. Its peristaltic locomotion is cool to watch. The video
speeds up as you go.

Grunt sculpins Rhamphocottus richardsonii.  

Swell shark Cephaloscyllium ventriosum that you can
pet! Swell sharks got their name because when threatened,
they gulp lots of water and swell in size.
