The shallow marine and tropical ostracod taxon Kotoracythere inconspicua(Brady) is encountered from the surface sediments of Indian waters Fifty-Two sediment and bottom water samples were collected over an year, representing the four seasons, in a transect (depth 0-13 m) off Rameswaram, southeast coast of India. Living specimens of this species are found in all the seasons. Systematics and ecology of the species are presented Biogeographically, this taxon has an extremely wide distribution in tropical, littoral zones of all oceans, excepting east Pacific. Its wide geographic distribution is explained through currents and by passive dispersal by ships.

Abstract


The shallow marine and tropical ostracod taxon Kotoracythere inconspicua(Brady) is encountered from the surface sediments of Indian waters Fifty-Two sediment and bottom water samples were collected over an year, representing the four seasons, in a transect (depth 0-13 m) off Rameswaram, southeast coast of India. Living specimens of this species are found in all the seasons. Systematics and ecology of the species are presented Biogeographically, this taxon has an extremely wide distribution in tropical, littoral zones of all oceans, excepting east Pacific. Its wide geographic distribution is explained through currents and by passive dispersal by ships.
