The longjaw mudsucker (Gillichthys mirabilis) is a species of goby (family Gobiidae) found along the Pacific coast of California and Baja California. Known for its distinctive elongated jaws and robust body, this species can reach up to 21 cm (8 inches) in length, making it one of the larger gobies in its habitat. Adapted to estuarine environments, the longjaw mudsucker has evolved to survive short periods out of water, utilizing tidal mudflats and sloughs as its primary habitat.
