The pointed- tailed serpent spine ( Lumpenus lampretaeformis ) is a slender marine fish from cold regions of the North Atlantic. Its distribution area extends from Svalbard and the Barents Sea south along the coast of Scandinavia and the North Sea coasts. It is also found on the south coast of Greenland , near Iceland , around the Faroe Islands and on the coasts of the Shetland Islands and Scotland . An isolated population in the Baltic Sea probably reached their habitat at the end of the Ice Age during an initial saltwater influx ( Yoldia Sea ). The subspecies Lumpenus lumpretaeformis serpentinus occurs in the northwestern Atlantic from Labrador and Newfoundland to Massachusetts .

features

The pointed-tailed snake spine has an eel-like, elongated body that is a maximum of 50 cm long. From a length of 20 cm and an age of two years, the fish are sexually mature. The caudal fin is narrow and pointed, which has contributed to the German naming of the fish. The dorsal fin extends almost the entire length of the body, the anal fin over 2/3 of the body length. The fish are yellowish-brown in color. The body is patterned with numerous, irregular brown spots.

Way of life

Pointed-tailed serpent spines live in Y-shaped tubes in the muddy seabed at depths between 30 and 370 meters, mostly between 40 and 100 meters. They feed on small crustaceans , molluscs , brittle stars and worms. They are also likely to spawn in their tubes. The females lay around 1000 eggs, which are guarded by their parents. The hatching larvae are pelagic . The spawning season is from December to January.
