The present work is a biodiversity study on some caprellids from the Northern Red Sea coast with their occurrence and distribution in different habitats in relation to water depth. From late 2019 to early 2020, a total of 67 individuals were collected from Hurghada and Shalateen, Red Sea coast by snorkeling and SCUBA diving, from five different depths (0.5, 5, 15, 25, and 35 m). A total of 7 caprellid species belonging to six genera and two subfamilies were recorded from Hurghada site, and only 5 species were recorded from Shalateen site. Phtisica marina Slabber, 1769, Metaprotella sp., and Deutella sp. were recorded for the first time from the Red Sea waters. These new records are significant in terms of increasing the known species diversity of the Red Sea fauna. Paradeutella multispinosa was the most abundant caprellid and was represented by 46.3% at Shalateen, followed by Hemiaegina minuta (31.7%) at Shalateen and (50.0%) at Hurghada. SIMPER analysis showed that the caprellids, P. multispinosa, H. minuta and P. marina, were the most contributing species to the dissimilarity between the two studied sites. Depth and habitat composition directly influenced the total caprellid abundance and diversity at both sites.
