Dear Dr. Kazmi, this is a squid yes.... if there is a picture taken on the dorsal and ventral side, it might be good. Fins can at least help one to narrow down on the family and then structures in arm, suckers, hectocotylus, all can be helpful in identification. If your specimen is from Arabian sea, yes, Todarodes genus has been reported. May be the attached file might be of some help. All the best..
