Polycopidae is a
family of marine
ostracods. Its members are related to animals in the suborder
Halocypridina
Halocypridina is a suborder of seed shrimp in the order Halocyprida
The Halocyprida is one of the two orders within the Myodocopa, in turn a subclass of the ostracod
Ostracods, or ostracodes, are a class of the Crustacea (class Ostracoda) ...
, but are sufficiently distinct to be placed in the sub-order Cladocopina. There is even some speculation that a separate order may be warranted.
The genera in the family differ from the other suborder, Halocypridina, in several features: the central
adductor muscle scars are in a triangular (3 scars) or half-rosette (15 scars) pattern, they lack sixth and seventh limbs, and the maxilla (=fourth limb) has both an exopod and endopod (the maxilla in the Halocypridina lacks an exopod).
