Definition of Crinoidea in English:

Crinoidea

plural nounkrʌɪˈnɔɪdɪəkrīˈnoidēə

Zoology

A class of echinoderms that comprises the sea lilies and feather stars. They have slender feathery arms and (in some kinds) a stalk for attachment, and were abundant in the Palaeozoic era.
Example sentencesExamples
- Especially important concerns are homology of aboral cup plates, origination of the Crinoidea, early morphologic diversification, phylogeny of the cladids, and definition and early phylogeny of the Articulata.
- The Crinoidea as a whole is regarded as monophyletic, but from whence this clade was derived and where it fits within the Echinodermata are matters of debate.
- This study reports the mtDNA sequence and genome map for a member of the echinoderm class Crinoidea, or feather stars, that is generally considered to represent a primitive echinoderm lineage.
- The trophic history of the Crinoidea is well preserved in the fossil record.
- Important taxa removed from the Crinoidea since 1978 include the coronate echinoderms; the Hemistreptocrinoidea, and Echmatocrinus.

Origin

Modern Latin (plural), from Greek krinoeidēs 'lily-like', from krinon 'lily'.
