Crinoids – "Like a lily"

Crinoids are marine animals that are part of the class Crinoidea. The name "Crinoidea" originates from the ancient Greek word κρίνον (krínon) "a lily", with the suffix "-oid" meaning "like". The crinoids, which in their adult form are attached to the seafloor by a stalk, are commonly called sea lilies.
