==Description==
Like [extant](/source/Extant_taxon) crinoids, ''Delocrinus'' species was anchored to a hard surface by a [holdfast](/source/holdfast_(biology)) out of which grew an articulated stalk. On top of this was a [calyx](/source/Calyx_(anatomy)) with a number of feather-like arms. Each arm bore short branches known as [pinnule](/source/pinnule)s and from these [cirri](/source/Cirrus_(biology)) were extended which sifted [plankton](/source/plankton) from the water flowing past.<ref name=Dorit>{{cite book |title=Zoology |url=https://archive.org/details/zoology0000dori |url-access=registration |last1=Dorit |first1=R.
