| Abstract | ||
| This paper deals with the taxonomy and ecology of 35 shells of Mollusk species identified from 12 samples collected from El Malaha Rayan offshore area. The study area is situated between south wadi El Malaha Rayan and Wadi El Malaha El Atchan offshore area. The study area has a length of 300 m and a width of 150 m. and El Malaha Rayan offshore areas represent the tidal and littoral zones.There are four wadies passing through the area of Wadi El Malaha Rayan and they pour their Flash flood in the Gulf of Aqaba. The marine environment of the study area is not influenced by the flash flood of the four wadies (Wadi El Wageran, Wadi El Malaha Rayan, Wadi El Malaha El Atchan and Wadi El Mohaymed). There are two groups of cluster analyses in the dendogram. The first group (A) located in the Tidal zone and include 33 Mollusk species (14 species from class Bivalvia and 19 species from class Gastropoda). These species exists in warm turbid water mostly caused by flash floods and they represent the tidal zone.The other group (B) located in the littoral zone and include 35 Mollusk species (14 species from class Bivalvia and 21 species from class Gastropoda). | ||
