Abstract: Present study consists rare batoids from north-eastern Arabian Sea. A specimen of Dasyatis microps (101.0 cm DW) and Pteroplatytrygon violacea (49.5 cm DW) respectively were collected in a trawler, operating south off Mumbai in the Arabian Sea, north-west coast of India. The present record of these elasmobranchs from the northern Arabian Sea shows their extended range of occurrence around the Indian coast, which is earlier reported from south-east and south-west coast of India. The morphometric measurements of the specimens collected were compared with previous records. In the same fishing area, pregnant Rhynchobatus djiddensis (254.0 cm TL) and a juvenile R. djiddensis (44.0 cm TL) was also caught in shallow coastal waters at 40 m depth. Biological observations on Dasyatis microps and Rhynchobatus djiddensis also presented.
