crinoid etymology

Etymology:

The word "crinoid" is derived from the Greek words:

• "krinon" (κρῖνον), meaning "lily"
• "-oid" (εἶδος), meaning "form" or "shape"

Meaning:

A crinoid is a marine invertebrate animal belonging to the phylum Echinodermata. They are characterized by their delicate, lily-like appearance and their stalked or unstalked body. Crinoids are also known as "sea lilies" or "feather stars."

Origin:

The term "crinoid" was first used in 1816 by the English naturalist William Elford Leach to describe a group of fossil animals that resembled the modern sea lily Comatula. These fossils were later recognized as belonging to the extinct class of echinoderms known as Crinoidea.
