Pentremites
Pentremites is an extinct genus of blastoid echinoderm belonging to the family Pentremitidae.
Description.
These echinoderms averaged a height of about but occasionally ranged up to about 3 times that size. They, like other blastoids, superficially resemble their distant relatives, the crinoids or "sea lilies", having a near-identical lifestyle living on the sea floor attached by a stalk. They trapped food floating in the currents by means of tentacle-like appendages.
