Distribution

Holothuria arguinensis is restricted in distribution to the northeastern Atlantic, from Peniche, Portugal, to Mauritania, and the Canary Islands. It has recently been found colonizing the waters of the Alborán Sea in the western portion of the Mediterranean Sea.

Behavior

This sea cucumber is a nocturnal species.

Habitat

This sea cucumber lives on sandy and muddy ground, in flat areas protected from the surf, in depths down to 52m.

Reproduction

Members of the class Holothuroidea are gonochoric and have only one gonad. Spawning and fertilization are both external and some exhibit brooding. Life cycle: Embryos develop into planktotrophic larvae (auricularia) then into doliolaria (barrel-shaped stage) which later metamorphose into juvenile sea cucumbers.

Food

Its diet consists of detritus, debris, invertebrates and sediment. It forages on Cymodosa nodosa and Zostera noltii.

Uses

Holothuria arguinensis has a nutritional value similar to that of other commercial sea cucumber species and
is suitable for human consumption. It is a commercial sea cucumber species from the northeast Atlantic Ocean and Mediterranean Sea that has largely been studied for aquaculture.
