[3] This family consists of bottom-dwelling marine sculpins shaped like tadpoles, with large heads and bodies that taper back into small, flat tails.

Members of the family generally have large, leaf-like pectoral fins and lack scales, although some species are covered with soft spines.

The blobfish has a short, broad tongue and conical teeth that are slightly recurved and are arranged in bands in irregular rows along the premaxillaries; canines are completely absent.

[7][8] The intense biological pressure to conserve energy within deep sea fish seems to be true across many species; most of them are long lived, have a slow rate of reproduction, growth, and aging.

Furthermore, studies have shown that the Psychrolutidae species displays a wide range of reproductive patterns, which include group synchronous maturation and extended batch spawning, which highlights their adjustment to deep sea habitats.

Categorized as the predator of the deep sea they have no real predatory issues; a big help to aid in their energy saving.

[10] Reproductively the blobfish have been seen gathering in large numbers to lay their pinkish eggs in a single surrounding nesting area.
