The Pacific Flatnose comes from a family of cod-like fish, which are only distinguishable by their skeletal structures and swim bladders. They have short heads, pointed snouts, and chin barbels. They’re coloring is variable ranging from pale blue-gray or olive green to dark violet or black. Their fins are darker on the outer edges.

Pacific Flatnose feed on bottom-dwelling invertebrates. Several Pacifc Flatnose have been observed at Axial Caldera. They are as large as 75cm (29.5in) in length and weigh up to 2,100g (4.6lbs).
