Pinnotheres pisum is a small crab with a carapace between about 2−1 and 18 mm. wide. The females are commonly found parasitic in the mussel, Mytilus edulis, though they have been recorded from other bivalves. The males are free-swimming and are comparatively rarely found in mussels. These small crabs are never abundant, and not more than one female has ever been found in a mussel.

These genera, placed by systematists in widely different groups, resemble one another closely in many details in their larval stages and are here purposely described together in order that a comparison may be made.

It is suggested that a two-host life cycle may be necessary, that the soft adult male form is an intermoult condition, and that the crabs show no tidal preference in invading hosts.

Natural history of the pea crab in Wellington Harbour, New Zealand

The pea crab Pinnotheres novaezelandiae Filhol (Brachyura: Pinnotheridac) infests the mussel Perna canaliculus (Gmelin) in Wellington Harbour, and shellfish below the level of low water neap tide are more heavily infested than those above this level.
