First Record of Arrow Gaper, Champsodon sagittus Nemeth, 1994 (Family: Champsodontidae) from Bay of Bengal, Eastern Indian Ocean


Champsodon sagittus, a species belonging to group popularly known as gapers has earlier known to occur in a narrow region of Indo-pacific along the coast of Australia, Philippines and Indonesia. The current report is the first record of the species from the Bay of Bengal, suggesting its possible wider distribution of the species in Indo-pacific Ocean. C. sagittus can be separated from other congeneric species by the combination of two gill rakers of upper limb, naked belly, five pair of sensory papillae on snout and no expansion of haemal spine The study also gives an insight into its depth of occurrence and habitat sharing with deep sea crustaceans.
