WHAT DOES CRINOID MEAN IN ENGLISH?
Crinoid
Crinoids are marine animals that make up the class
Crinoidea of the echinoderms. Crinoidea comes from the Greek word
krinon, "a lily", and
eidos, "form". They live both in shallow water and in depths as great as 6,000 metres.
Sea lilies refer to the crinoids which, in their adult form, are attached to the sea bottom by a stalk.
Feather stars or
comatulids refer to the unstalked forms. 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. There are only about 600 extant crinoid species, but they were much more abundant and diverse in the past. Some thick limestone beds dating to the mid- to late-Paleozoic are almost entirely made up of disarticulated crinoid fragments.
Definition of crinoid in the English dictionary
The first definition of crinoid in the dictionary is any primitive echinoderm of the class Crinoidea, having delicate feathery arms radiating from a central disc. The group includes the free-swimming feather stars, the sessile sea lilies, and many stemmed fossil forms. Other definition of crinoid is of, relating to, or belonging to the Crinoidea. Crinoid is also shaped like a lily.
