Early crinoid faunas, characterised by a range of stem lengths and arm branching patterns, have provided vital clues regarding ancient marine ecosystems and the processes of niche partitioning.

Researchers discovered Endoxocrinus kexuei, a new crinoid species, in the South China Sea, living on cold seep habitats over 2,700 feet deep.

The crinoid has between 20 and 22 arms that can reach up to 5.5 inches long, according to the study. The animal’s stalk is shorter than its arms, about 2.5 inches long, researchers said.
