Hairy Sea Cucumber

Well, it's that time of year again, time to renew the web hosting. And for those of you that don't know, that has become a lot more expensive than it used to be. Fifty dollars a year is now several hundred. Not to mention the price of domain names has gone up ten-fold.

And I just found out that the nice folks at PayPal disabled all my Support buttons, and I never got a notice (although that may be my fault.) In any case, it is all working again now, so if you would like to make a small donation to help defray these costs, it would be greatly appreciated.

Sclerodactyla briareus

Size: to 6", larger offshore

The Sea Cucumber is not a worm, but an echinoderm, related to the starfish. If you look closely, the 5-way symmetry is still evident. Sea Cucumbers live buried in sandy or muddy bottoms less than 60 ft deep. Find them by the volcano-shaped mounds they make.

Echinoderms

Echinoderms ( literally "spiny skins" ) are among the strangest animals on the planet. They start out as bilaterally symmetric larvae but grow into a 5-way body symmetry as adults. Some species show six, seven, or even higher levels of symmetry. Worm-like Sea Cucumbers have re-evolved a bilateral body plan over the underlying 5-way plan. Because of certain developmental traits, it is felt that despite their strangeness, echinoderms are actually more closely related to chordates than any other group.
