Corocrinus calypso
alt: i wanted to go more colorful with this crinoid (an echinoderm with radial arms jutying out of a central cup atop a stalk, like a sea flower with feathery tentacles), here depicted with bands of blue and yellow for the arm and stalks, with red pinnules, the feather bits on the arms. most crinoids today live in the deep sea, but corocrinus and many others in the paleozoic lived in shallow water. Corocrinus seems to have this beautiful triangle/hexagon grid skeleton thingy on its cup instead of the usual hexagon plates
