Montagu's Seasnail

Liparis montagui

Montagu's Seasnail is a small marine fish that belongs to the seasnail family, Liparidae. It can reach a maximum length of 15.5 cm and is characterized by its elongated body shape. Unlike some related species, Montagu's Seasnail typically has no overlap of its dorsal and caudal fins, although there can be rare overlap between its anal and caudal fins. This species is found in the northeastern Atlantic, with its range extending from the North Sea to the Norwegian Sea, around the British Isles, and as far north as the Barents Sea. It inhabits temperate waters and is usually found from the intertidal zone to depths of 30 meters, often hiding under stones or clinging to algae in these environments. Montagu's Seasnail primarily feeds on crustaceans, including gammarid amphipods in intertidal zones and shrimps and small crabs in subtidal areas. Its breeding season occurs in winter, with eggs being deposited on algae or polyp colonies. The young can also be found in areas like the Wadden Sea. Divers encountering this species might find it in shallow waters, where it exhibits cryptic behavior, often blending in with its surroundings to avoid detection. The conservation status of Montagu's Seasnail is listed as Least Concern by the IUCN Red List. While it is harmless to humans and of no interest to fisheries, it contributes to the ecological balance of its habitat by feeding on small invertebrates.
