The Chirolophinae are a subfamily of the spiny ridges (Stichaeidae) in the partial order of the eel mother relatives (Zoarcales). All twelve species in the group are bottom-dwelling marine fish found in the cool waters of the northern Pacific Ocean.
They have an elongated body covered with scales, the head being scaleless. Very little is known about the life of these animals.
Chirolophis nugator grows to 15 cm in size and is usually found in rocky habitats. The mosshead often hides in holes, crevices, and tube-worm tubes, so that only the head is visible. The blenny is variable in colour from light brown to light red. It is said to be very shy. Divers report that Chirolophis nugator can also be found in empty bottles, which unfortunately lie in the sea as garbage.
Chirolophis nugator feeds on small fish and invertebrates and is itself prey to larger fish.
