Leptosynapta bergensis is a species of sea cucumber of the family Synaptidae.[2][3]

Description

[edit]

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).[4]

Distribution

[edit]

It can be found on all coasts of Great Britain and Ireland and Scandinavia;[5] it is common in Strangford Lough.[4][6] It is generally found further north than Leptosynapta inhaerens.[7]

Habitat

[edit]

Leptosynapta bergensis lives from low on shore to over 100 m (330 ft) deep, buried in muddy sand.[8]

Life cycle

[edit]

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.[9]
