We present new records extending the known geographic range of four species of parrotfishes (family Scaridae) in the Gulf of California, Mexico: Scarus compressus, S. ghobban, S. perrico and S. rubroviolaceus. The presence of these species in the northern gulf is relevant considering their ecological role as consumers of algae and mollusks, and as producers of carbonated sediments in the reefs, which is not currently played by any other fish in that area. The records of Scarus spp., a warm-water genus, might point out that oceanographic conditions in the northern Gulf of California are becoming acceptable for tropical species and thus, an increase in the number of range extensions might occur in years to come.
