Feather Red Sea Lilly PDF Print E-mail

Looking for an addition to your tank that has changed little in the last 350 million years?  Plus one that’s colorful, unique, and easy to care for?

 

No, we’re not talking about horseshoe crabs (they’re actually older).  We’re talking about the Feather Red Sea Lilly.  Actually classified in the starfish family (Echinodermta), Feather Red Sea Lillies, have many of the same features as other star fish.  These features include radial symmetry,   Technically, they’re called Crinoids.

Crinoids are characterized 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 recognized, 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.

 

The majority of living crinoids are free-swimming and have only a vestigial stalk. In those deep-sea species that still retain a stalk, it may reach up to 1 metre (3.3 ft) in length, although it is usually much smaller. The stalk grows out of the aboral surface, which forms the upper side of the animal in starfish and sea urchins, so that crinoids are effectively upside-down by comparison with most other echinoderms. The base of the stalk consists of a disc-like sucker, which, in some species, has root-like structures that further increase its grip on the underlying surface. The stalk is often lined by small cirri

 

Crinoids are filter feeders, absorbing foods primarily through their feet and the many arms which wave in the current.  Making sure they have adequate marine snow (zoo plankton) is important for their success.
