Chaunax is a genus of bony fish in the sea toad family Chaunacidae.[1] They are found in tropical and subtropical oceans around the world and most species are found at depths between 180 and 1,100 m (590 and 3,610 ft), but C. endeavouri occurs as shallow as 50 m (160 ft) and C. fimbriatus as deep as 1,985 m (6,512 ft).[2][3] Depending on the exact species involved, they reach a total length of 11–40 cm (4.3–15.7 in).[4]

Description

The Head and body of the Chaunax suttkusi fish is a pale to rosy pink, with the tops and sides of the head and fins being red; the upper body frequently has yellow dots; while the lower surfaces are whitish. Lures are uniformly pale to dusky on all surfaces with dark threads in the nose cavity.[10]

Habitat and diet

Members of the fish are primarily found near the ocean floor, along coral reefs, oysters, soft bottoms, and near muddy substrates. Their eating habits revolve around the oceanic floor, where there are occasionally only a few small marine species to be found. As a result, they developed an energy-saving mechanism to allow them to survive on less food. The fish family is a consistent predator. They move slowly enough that their prey is unaware of their existence. In the depths of the ocean floor, they prey on nearly anything, such as small marine fishes that may be part of their diet.
