Description

This species of holothurian is pink with longitudinal muscle-bands and a slender and soft body. It has twelve pinnate tentacles and no tube-feet. Each tentacle has 8–11 pairs of digits. It grows to 10–30 cm (3.9–11.8 in).[5]

Distribution

It can be found on all coasts of Great Britain and Ireland and Scandinavia;[6] it is common in Strangford Lough.[5][7] It is generally found further north than Leptosynapta inhaerens.[8]

Habitat

Leptosynapta bergensis lives from low on shore to over 100 m (330 ft) deep, buried in muddy sand.[9]

Life cycle

Leptosynapta bergensis is gonochoric and has only one gonad. Spawning and fertilization both happen externally. Embryos develop into planktotrophic larvae (auricularia), then into doliolaria (barrel-shaped) and then metamorphose into juvenile sea cucumbers.[1]
