Abstract: Sphaeroma terebrans Bate, one of the most destructive wood-boring isopod crustacean occurring in the Cochin harbour region was taken up for investigations on its habitat, breeding, attack on timber, salinity tolerance and respiration. The respiration of the animal under different stresses was noted using an instrument fabricated in the laboratory. Of the various hydrographic conditions of the Cochin harbour region studied, salinity is found to be the most fluctuating factor and the variations are largely influenced by the seasonal rain fall from one side and the tidal currents on the other.In spite of the great fluctuations in salinity, Sphaeroma terebrans occurs throughout the year in the Cochin harbour region, though their number varies in different months. Exposure tests show that Sphaeroma terebrans can remain for about 20 to 24 hours outside water in a damp atmosphere.
