Cabezon

The Cabezon is a large species of sculpin which can be found around the Pacific Coast of North America. The name "Cabezon" comes from Spanish and means "big head" and its genus actually translated to "Scorpionfish" even though they belong to a completely different family.
They can grow to substantial sizes and the size usually determines their sexual maturity. Usually the females have a greenish color, while most of the males have a reddish color.
