The bigeye rockling's maximum length is 25 cm (9.8 in).[2] It is silvery-pink in colour, its back mottled with medium brown, and the eyes more than half the length of its snout.[8] The first dorsal spine is followed by fleshy filaments. There is one barbel on the lower jaw and two on the snout. The upper jaw has long pointed teeth.[9][10]


Bigeye rockling live in the northeastern Atlantic Ocean.[11] It is demersal, living at depths of 150–530 m (490–1,740 ft).[12]


Bigeye rockling feed on crustaceans.[9] It breeds in early spring.[8]
