Creseis acicula

Creseis acicula (pteropod mollusc)

Location: 100 km offshore from Barnegat, NJ. Depths of >200 meters. Caught while drifting a plankton net (363 micrometer mesh) from the back of a boat at night. Summer 2009.

Notes: This small seagoing snail has its head and foot tucked into its transparent shell for protection. The foot is modified into “wings” that flap to propel Creseis through the water.

Pteropods are usually found offshore or in occasional nearshore intrusions of ocean waters.
