oyster crab
Quick Summary
An oyster crab, also known as a pea crab, is a tiny crab belonging to the genus Pinnotheres. These small crustaceans live commensally within the mantle cavity of various bivalve mollusks, such as oysters, mussels, and scallops, as well as in echinoderms and polychaetes.123
The female oyster crab, typically pinkish-white and up to 2 cm across, resides in its host, while the smaller, free-swimming males are rarely seen. These crabs do not derive nourishment from their host, meaning they live on or in another animal without feeding on it. The female carries her eggs with her back legs until they hatch, after which the larvae swim freely before settling into a new bivalve host.2
