First Record of the Thai Bobtail Squid, Euprymna hyllebergi Nateewathana, 1997 (Cephalopoda: Sepiolidae) from the Arabian Sea

The small benthic squid Euprymna hyllebergi is reported for the first time from the southeastern Arabian Sea along the Indian coast. A total of 97 individuals (56 females and 41 males) were collected from commercial trawls. The dorsal mantle length (DML) of the individuals ranged from 21 to 46.5 mm for males and 24 to 50 mm for females. This species has previously been reported only from the Persian Gulf, the Gulf of Thailand, and the Andaman Sea. Detailed morphometric, meristic, and molecular data for this species are provided. The documentation of this squid from India expands the catalogue of cephalopod fauna of the Arabian Sea, shedding new insights on its distribution patterns.
