Penilia avirostris with eggs (water flea)
Collected: 2-5 km offshore from Chincoteague, VA. in depths of 5-7 meters . Caught using an epibenthic sled (365 micrometer mesh). Summer 2005.
Notes: Penilia is one of the most common water fleas in nearshore ocean waters and high salinity estuaries of the mid and south Atlantic coast, where it can occur in very high densities for brief periods. Penilia can feed on extremely small particles including bacteria, a rare accomplishment among crustaceans.
ID Note These delicate water fleas (cladocerans) are virtually transparent when alive as seen below
