Caecijaera horvathi
Taxonomic Group: Crustaceans-Isopods


Caecijaera horvathi is a small, blind, marine isopod which lives as a commensal in the burrows of the wood-boring isopod Limnoria spp. It was first described from Los Angeles-Long Beach harbor, California in 1951 and is also known from Hawaii and Cuba. Its global distribution and native range are unknown. We consider this species introduced in California because its host, Limnoria tripunctata, is non-native to this region. Further work on the distribution and origin of C. horvathi and L. tripunctata is needed.
