The Prickleback fish always seen perched in this posture. Therefore one could be one of several species that occur at this depth (127 meters).

They are hard to identify to the species level without holding them.

They also live  in cooler seas of the northern hemisphere, typically in shallow inshore waters.

Ranging from southern Oregon down to the northern reaches of the Mexican state of Baja California, monkeyface pricklebacks are coastal fish that live in rocky, tidal areas close to shore. First described by Girard in 1854, the fish spawn on the sea floor and show some nest guarding behavior. While young monkeyface pricklebacks feed on zooplankton and crustaceans, adults are primarily herbivorous, feeding on red and green algae.

Adults have few predators other than humans, but young fish are vulnerable to birds and other fish, such as grass rockfish.[2] The species reaches a maximum size of 76 cm (30 in) and may live up to 18 years. The heaviest monkeyface prickleback recorded to date was just over 6 lb (2.7 kg).
