Brittle star pluteus larva

Brittle star pluteus larva

Location: 100 km offshore from Barnegat, NJ. Depths of >200 meters. Caught while drifting a plankton net (365 micrometer mesh) from the back of a boat at night. Summer 2009.

Notes: Several different echinoderm groups have pluteus larvae. This one, from a brittle star (or a close relative), is more properly termed an “ophiopluteus”.
