Range extension of five crustacean species in the Gulf of California, Mexico

Northernmost range extensions in the Gulf of California, Mexico, are reported for five crustacean species, one from the family Portunidae and four to the family Squillidae. These extensions cover the central and northern portions of the Sonora coastline (Agiabampo and Puerto Peñasco) and the eastern coast, off San Luis Gonzaga and San Felipe, Baja California, Mexico. The species exhibiting the greatest range extension was Cloridopsis dubia (H. Milne Edwards, 1837), spanning 830 km.
