The larvae are planktonic and undergo several changes in body style and shape until they settle to the seabed. In male crabs, and in non-breeding female crabs, the worm may live in the axils of the limbs and encyst. Females hold the eggs in place with wide abdominal flap equipped with haired pleopods (a feature absent in male Dungeness crab). The crab incubation period lasts for about two weeks until the crab larvae hatch and is then released into the ocean to fend for themselves.

A Dungeness crab holds eggs between her abdominal flap and body at the Aquarium’s Dungeness Crab Fishery Day. The planktonic larva of the worm settles on a suitable crab host and encysts on the exoskeleton. Pots must conform to construction guidelines that efficiently minimize their impact.
