Abstract:
Genus Glyphocrangon, the only representative of Family Glyphocrangonidae, comprises about 89 species. According to previous records, this species is known to inhabit a depth range of 145-410 fathoms in Bay of Bengal. A thorough scrutiny of literature revealed a detailed morphological description of G. investigatoris and little molecular database. As part of an exploratory research survey conducted in Bay of Bengal, specimens of this species were collected from trawl catches off Paradeep, Orissa. In our present study, an attempt was made to develop its DNA barcode based on mitochondrial Cytochrome oxidase subunit I (mtCOI) and to establish its phylogenetic relationship with other species of genus Glyphocrangon. The developed mtCOI sequences of G. investigatoris exhibited its genetic identity favoring its morphological description.
