Among them, 13 species were recorded before from Gulf of Aqaba and Heterocentrotus trigonarius was recorded for the first time from the study area. On the other hand, 2 species, Astropyga radiata and Diadema savignyi were recorded for the first time from the entire Red Sea. Based on the present data and other studies, a key for all recorded species was constructed and expandable when possible. In addition, notes on the geographical distribution and ecology of these echinoids were discussed. [ABSTRACT FROM AUTHOR] |
