Range and Identity
Nematistius pectoralis ranges from southern California toward Peru, including the Galapagos Islands. It is rare north of Baja California in the checked account. A northern record therefore deserves its exact locality rather than being treated as evidence of equal abundance along the entire coast.
Habitat and Behavior
Adults frequent shallow coastal areas and sandy shores. Juvenile tide-pool observations add another habitat used during early life. A small fish in enclosed shore water and a large fish moving along a beach can represent different stages within the same coastal species.
Food and Life History
The upper references are 163 centimeters fork length and 51.7 kilograms. A common-size value in the source uses total length, which is a different convention. The sparse summary does not establish a detailed diet or complete spawning calendar, so those details are not invented.
Field Note
Record the length method with a large catch. Fork length stops at the tail fork and should remain distinct from total-length measurements used for other coastal fishes.
