Description
The Longjaw Mudsucker is a unique brackish water goby known for its elongated jaws and ability to tolerate a wide range of salinities and oxygen levels. It inhabits estuaries and mudflats along the Pacific coast, often burrowing into the substrate. This hardy fish is an opportunistic carnivore, feeding on various small invertebrates and fish.
