Abstract

The aim of this study is to provide an additional report of Holothuria sanctori Delle Chiaje, 1823, a sea cucumber species from the Akkum rocky bottom habitat located off the coast of Mersin.The individual of H. sanctori was collected from a rocky crevice at 8 meters depth. The distinctive morphological characteristics of H. sanctori were noted. H. sanctori was observed to have ossicular structures forming buttons with different sizes and numbers of holes. The body color of the H. sanctori specimen is dark brown and has yellowish ossicles on the body surface.
