I will post a pic later tonight or tomorrow, but I bought a HUGE hermit crab over the weekend. Its size is between a Regular Baseball and a Softball. Anyways, on the shell of this crab is 5 or 6 Volcano looking things.
When you look at these Volcano type things, little things stick out, and wave in the water in one quick motion. Like it sticks out for a total of maybe 1 second each time it does it. They kind of look like Feathers sticking out. Anyone have a clue as to what these are?
I will try to get an "action" pic if I can and post it.
