Eurydice spinigera Hanson, 1890

ID Difficulty

Identification

Eurydice are small, fast-swimming predators and scavengers with oval bodies and elongated pleotelsons. The peduncle of the antenna has four segments, whilst the second segment of the antennule is at a right angle to the first. The body is off-white with various darker markings, and the eyes are prominent.

E. spinigera is distinguishable from E. pulchra and E. affinis in having a concave hind margin on the pleotelson with two prominent spines at each corner, the space between filled with plumose setae. The shape of the coxal plates in this species is particularly distinctive, with their posterior corners (especially those of pleon somite 6) having long points.

Distribution and Habitat

E. spinigera is essentially an off-shore species, though it may perhaps turn up intertidally over sand on southern and western shores.
