Sea lily (lat. Bourgueticrinida) is a sea animal that lives deep in the ocean. It belongs to the order of crinoids. Crinoidea comes from the Greek word krinon, “a lily”, and eidos, “form“. They are attached to the seabed by a slender stalk and are known as sea lilies.
While other groups of crinoids flourished during the Permian, bourgueticrinids along with other living orders did not appear until the Triassic, following a mass extinction event in which nearly all crinoids died out.
They are animals of a brittle beauty that is usually hidden from human eyes.
