Abstract The tolerance range of healthy mantis shrimp ,Oratosquillakempi ,with body length of (10 .0 ± 0 .5 ) cm to water temperature , salinity and pH was investigated with progressive alteration in a laboratory .The mantis shrimp was shown to have strong adaptability to variation in salinity , water temperature and pH ,with the optimal ranges of 18—30 in salinity ,24-33 ℃ in water temperature and 7.0—9 .0 in pH . Only weak mantis shrimp were found to be dead at a salinity of 14 or 36 ,water temperature of 14 or 35 ℃ ,and pH 5 .0 or 10 .0 indicating that O .kempi is an euryhaline shrimp species with excellent tolerance to great fluctuation in water temperature ,salinity and pH .
