Caulolatilus princeps, commonly known as the ocean whitefish, is native to the eastern Pacific Ocean. Its geographical distribution extends from the southern coast of California, USA, through Baja California, Mexico, and as far south as Peru. It is also found around the Galapagos Islands.

Caulolatilus princeps typically inhabits temperate to subtropical marine environments. It is found in ocean waters at depths ranging from 10 to 200 meters, often over sandy or rocky substrates. The species prefers areas with moderate currents and is often found near kelp beds and rocky reefs.

The ocean whitefish plays a role as both predator and prey within its ecosystem. It feeds on a variety of benthic invertebrates, small fish, and crustaceans, contributing to the control of these populations. In turn, it serves as prey for larger predatory fish and marine mammals. This species is often targeted by recreational and commercial fisheries due to its desirable taste, influencing its ecological interactions.
