Abstract

Cymbula safiana, which is considered an endangered species, according to UNEP, is present on the rocky shores of the Libyan western coast of the Mediterranean Sea. This study aimed to describe and define the presence of Cymbula safiana on some beaches of the Zawiya region of the Mediterranean coast. Five trips were conducted to the following beaches, Judaim, Delah, Al-Mutarad, Sorman, and Sabratha from December 2018 to April 2019. Randomly, 101 samples were collected from the tidal areas of all beaches of the study area. The results indicate that the presence of C. safiana was recorded in four beaches included in the study, and they were as follows Judaim beach with a percentage of 19.8%, Delah beach at 39.6%, Surman beach at 26.7%, and Sabratha beach with a percentage of 13.9%, with no presence of C. safiana species in Al-Matrid beach. The absence of C. safiana species at Al-Matrid beach could be due to several reasons, such as commercial and industrial activities and human expansion in digging rocky beaches. Although this invertebrate species is considered endangered on the rocky shores of the coast of Libya, this species has rarely been the subject of study on the shores of the Libyan coast, and that is why the outcome of this study recommends conducting extensive studies of the species and its distribution along the rocky shore of Libya.
