Crinoids are a kind of sea animal that look like a flower growing on thick stems. They are sometimes called sea lillies because of their flower like appearence. It is the flower that catch its food. The crinoids attach themselves to the bottom of the sea floor or a rock or a piece of wood with the root-like holdfast. There are also free swimming crinoids called feather stars or comatulids.

Crinoids are echinoderms, and are related to starfish and sea urchins. All echinoderms display radial symmetry with 5 segments. The first crinoids appeared in the fossil record during the ordoviician period. They were so common during the Paleozoic Era that they contributed to reef building. Almost all varieties of crinoids have been extinct since the end of the Triassic period, but a few species exist to this day.
