Fluffy Sculpin

Oligocottus snyderi





Fluffy sculpins can be found in tidepools, hidden among the algae (1). Their color is extremely variable; ranging from green to reddish to pink (1). Generally they have a spotted or mottled color pattern with a blue underbelly (1). Morphologically they are between 8-9 cm and have a smooth, scaleless body (1). They primarily consume amphipods and polychaetes, a type of segmented worm, though at larger sizes fluffy sculpins can eat shrimp, crabs and isopods (2). While they have a short life span of 1.5 years they maximize their lifespan by rapidly growing and timing their reproduction for nutrient rich upwelling events (1).
