ostracod 2

Inshore ostracod

Location: Caught in a saltmarsh creek at Georgetown, SC using a net suspended in the tidal current.

Notes: Ostracods, with their bivalve shells, resemble mussels or clams at first glance. A careful look reveals jointed appendages sticking out between the valves, so an arthropod it surely is. This unknown species could be partially planktonic or just a benthic ostracod caught up in the current, we catch this species in the plankton with some regularity in saltmarsh creeks and in the coastal ocean.

Alas, there is no published information available to help identify nearshore species. This one resembles Cytheromorpha.
