Range and Identity
Leptocottus armatus occurs from the southeastern Bering Sea region toward northern Baja California. It is a sculpin rather than a freshwater bullhead catfish. Locality and the head’s defensive structures are useful parts of identification when common names differ among coastal regions.
Habitat and Behavior
Adults often remain in lower estuaries or nearby marine water, while some newly transformed young enter fresh water temporarily. Intertidal individuals can breathe air when exposed. These observations should not be turned into a universal claim that all life stages occupy the same salinity or survive unlimited exposure.
Food and Life History
Crabs, shrimps and amphipods are important recorded prey, with fishes, worms, mollusks and other animals also taken. The upper length reference is forty-six centimeters total length. A maximum weight is not inferred from the fish’s broad head or calculated from that upper body length.
Field Note
Record life stage and salinity at the observation site. A young fish briefly in freshwater can be part of an otherwise coastal and estuarine life history.
