Other occurring taxa included Cnidaria, Cladocera, Ostracoda, Amphipoda, Mysidacea, Pteropoda, Larvacea, and Chaetognatha
were represented by a small number of species (Table IV), contributed collectively 19.68% and about 1% of the species richness and total abundance, respectively.

The invertebrates comprised three classes of animals viz: Crustacea, nematoda, chaetognatha
. Crustaceans represented by copepod (Calanus finmarchicus), swimming crab (Callinectes sp.) and pink shrimp (Penaeus notialis) constituted 34.72, 9.64 and 7.12% by number and occurred in 57.29, 35.42 and 29.17% of the stomachs, respectively.

from the northern Arabian sea Collected eluring the cruise of Ins.
Twenty-one species from the phyla Annelida, Mollusca, Arthropoda, Platyhelminthes, and Chaetognatha
were identified from the experiments (Table 1).
Copepods dominated the community in all situations (> 70 in relative abundance), although Salpidae and Chaetognatha
were also abundant and persistent.
For the protozooplankton, the predominant taxa in the southeastern region (SBB) were tintinnids (Salpingella sp.), which contributed to the high densities in SSB1, and zooplankton such as copepods there is high densities, as well as the presence of representatives of other groups such as Cladocera, Chaetognatha
Among the holoplankton; copepoda, appendicularia, chaetognatha
, doliolida, medusae, pteropoda, salpidae and siphonophora were encountered in every season, amphipoda was encountered in spring and winter, cumacea was encountered in winter, foraminifera was encountered in summer, autumn and winter, heteropoda and ostracoda was encountered in spring, autumn and winter, and radiolaria was encountered in spring and winter.
