Merret's snailfish (Careproctus merretti), also called the snakehead snailfish,[2] is a species of fish in the family Liparidae.

[3][4] It is named for the British ichthyologist Nigel Merrett (born 1940).

[5] Merret's snailfish is silvery-pink in colour, with a black peritoneum.

Its hypural plate (expanded ends of the hypurals that form a wide, fan-like plate onto which the caudal fin rays are attached) is single, and there are no epurals.

[7][8] Merret's snailfish lives in the Porcupine Abyssal Plain; it is bathydemersal and non-migratory, living at depths of up to 3,990 m (13,090 ft).
