This is a video of a feather star swimming off the coast of Bali. What the hell is a feather star? Let me Wikipedia that for you while I dance around the office waving a feather boa hoping it disturbs my boss enough to give me the rest of the week off. I'm too proud to take a vacation.
Crinoids are marine animals that make up the class Crinoidea of the echinoderms (phylum Echinodermata). Those crinoids which, in their adult form, are attached to the sea bottom by a stalk are commonly called sea lilies. The unstalked forms are called feather stars or comatulids.
Crinoids are characterised by a mouth on the top surface that is surrounded by feeding arms. They have a U-shaped gut, and their anus is located next to the mouth. Although the basic echinoderm pattern of fivefold symmetry can be recognised, most crinoids have many more than five arms. Crinoids usually have a stem used to attach themselves to a substrate, but many live attached only as juveniles and become free-swimming as adults.
Ah yes, their anuses are located right next to their mouths. Good one, Mother Nature. Well, I guess I can add 'Not Being Born A Feather Star' to my list of things to be thankful for this holiday season.
Keep going for two videos, but skip to 1:30 in the first one for the feather star.
Thanks to n0nentity, who tried to tell me Poseidon gets drunk and makes new sea creatures he doesn't even remember the next day.
