Hairy Pincushion Urchin (Tripneustes gratilla) Video


Reef Club Meeting – May 2012 cont.


Here are a few more pictures from our last reef meeting (earlier post) that thought I would share. Great shots Kim!

Pincushion Urchin relieving himself


When I saw a bunch of small particles flying around in the tank I thought maybe the clams were kicking up a dust storm or that maybe the cardinals had released babies into the tank, but no. The pincushion urchin had gone to the top of the tank and was relieving himself on all of his tank mates below.  Guess he doesn’t much care for them, lol.

Orange Pincushion Urchin Walking All Over Squamosa Clam


After the lights went out on the tank I noticed the pincushion urchin (added last week) walking directly over one of the clams.  My first instinct was to get in there and pull it off but I decided to wait and see if the urchin did anything destructive. After what seemed an eternity, the urchin made his way across the top of the clam and on to “greener pastures.” The squami was fine. 🙂

Pincushion Hairy Sea Urchin (Tripneustes gratilla)


Got an orange pincushion sea urchin from my LFS (Reefmissoula) on Wednesday.  He’s pretty cool to watch. 🙂
