Black sea cucumber

Hasan’s report published in 2009 included records identified as Holothuria atra in the April–May 2006 survey, which covered 18 sites in Al-Wajh, Thuwal and the Farasan Islands. The area names define the survey’s scope and do not by themselves establish a record of the species in every area.

The materials and methods section of a study published in 2015 reported collecting specimens that the researchers identified as Holothuria atra from the Thuwal area on Saudi Arabia’s Red Sea coast. This attributes the collection report to that study.
