A study of females showed that mature eggs are unusually large, up to 9.4 mm (0.37 in) in diameter. In total, there were up to 23 mature eggs for each female (each larger than 5 mm or 0.20 in in diameter), which were alternated with immature, small eggs, the number of which was about 850. Eggs of intermediate size were rarely seen.
The large egg size indicates continuous egg laying in hadal snailfish; some species spawn their eggs among cold-water coral, kelp, stones, or xenophyophores, and the males will guard the egg sometimes. [17] Liparids have ventral sucking disk that is used to attach to king crab and deposits its eggs inside the carapace of the gills. [19]
Like other snailfish, they lack scales and have a loose gelatinous skin; a few species are covered in prickly spines. [ 2 ] Most species of Careproctus are poorly known, but they feed on small animals and some have unusual breeding behaviors: At least C. ovigerus appears to be a mouth brooder where the eggs are carried and develop in the males ...
The snailfish that live in the northern hemisphere also display a higher starvation tolerance, which may be due to the triglycerol and cholesterol levels in this species. The snailfish have different lipid concentrations depending on their habitat, making some of them better-suited for longer periods without feeding than others. [41]
The eggs of Urosalpinx cinerea are contained in small transparent membranous parchment-like vases, each of which is attached by an expanded foot to some solid substance, usually the under surface of an overhanging rock, a little above low-tide mark. Each female deposits from ten or twelve to more than a hundred of these vases, the process of ...
Liparis fabricii, commonly known as the gelatinous seasnail or gelatinous snailfish, is a benthopelagic species of snailfish from the Arctic Ocean. It has a tadpole-like body with a maximum length of about 20 cm (7.9 in). It is brown to black in coloration with a distinctive dark peritoneum. It preys on small crustaceans and marine worms.

Usually they lay 20-50 eggs in rotting wood or below decaying leaves. Eggs are white and flattened, measure about 1 mm and hatch after 10–30 days. These gastropods reach their maturity only in the second or third season and can live 2–3 years. [ 3 ]
