Leptosynapta inhaerens (O.F. Müller 1776) (Echinodermata, Holothuroidea): a new record for the Belgian marine waters

This is the first record of Leptosynapta inhaerens (O.F. Müller, 1776) in Belgian marine waters and adds a second apodid species, the first being Leptosynapta minuta (Becher, 1906), to the Belgian holothuroid fauna. This paper contains a morphological description of the specimens, the habitat characteristics, and includes a world distribution map of L. inhaerens . Relationships between L. inhaerens and environmental data are discussed.
