Paradella dianae
Taxonomic Group: Crustaceans-Isopods


Paradella dianae is a marine and estuarine isopod. It was described from Bahia de San Quintin, on the Pacific Coast of Mexico, and its native range extends from San Diego Bay, California to Mazatlan, Mexico, including the Gulf of California. It has been widely introduced to warm-temperate and tropical harbors and coastal waters around the world. Populations are now found on every continent, except Antarctica, and on a number of oceanic islands. It is known from intertidal rocky shores, pilings, jetties, dock floats, seaweeds, mangrove roots, tubeworm reefs, and soft sediments. It may compete with other intertidal isopods, but negative ecological interactions have not been quantified.
