We went to Cholla Bay today and studied the soft sediment and the creatures that live there. We found a Pygmy Octopus taking shelter from the inter tidal conditions in one of the shells. Octopus are part of the Mollusca family and are known as Cephalopoda. Now for those of you who have no idea what a Cephalopoda is; here are some neat characteristics:
They have well developed heads with a large brain and advanced eyes. Octopus have no shell and tentacles armed with suction cups.

And although he was cute and fun to touch, he got into a fight with a crab and even drew blood from one our own (Yeltsy)! Eeek! I guess you never know what you'll find hiding in the sand!

Until next time, watch out for octopus and crabs!
