ARE CRINOIDS A SEA LILY?
Because of their “flower like” appearance, crinoids have been referred to as “sea lilies”, but do not be fooled: they are in fact animals. Crinoids belong to the phylum Echinodermata.
WHAT DID CRINOIDS EAT?
Crinoids are passive suspension feeders, filtering plankton and small particles of detritus from the sea water flowing past them with their feather-like arms. The arms are raised to form a fan-shape which is held perpendicular to the current.
