Behind the head, the body tapers rapidly to the caudal peduncle and there is a gelatinous layer between the skin and the muscle. The dorsal fin has eight spines and nineteen to twenty soft rays, and the anal fin has no spines and twelve to fourteen soft rays. The pectoral fins are broad and in larger individuals, have fleshy pads near their tips. The upper parts of this fish are grey or black and the underparts pale, with some indistinct mottling. It has 8 spines.

the emerging juvenile organisms still retaining remnants of the egg casing surrounding them. The eggs were free of sediment which makes it likely the adults were actively fanning them, the first known example of parental care in egg-laying deep sea fishes. Scattered around and among the sculpins were octopuses in the genus

The blob sculpin is native to the northeastern
Pacific Ocean where it is found on or near the seabed at depths from 500 to 2,800 m (1,600 to 9,200 ft). The bottom water temperatures in the area averaged around 2.4°C (36.3°F). For most of the egg nests observed, adult fish were keeping close

onto limestone-like rocks in the deep sea, and are known to brood large pinkish eggs in nests, actually lying on the eggs or in contact with them in many instances. The collected eggs measured an impressive 40 mm in length. However, numerous eggs began hatching prematurely upon being sampled, with
