EFFECTS OF TEMPERATURE AND SALINITY ON THE OXYGEN CONSUMPTION RATES AND BEHAVIORS OF THE NUDIBRANCH, JORUNNA FUNEBRIS (KELAART, 1858)
Temperature and salinity are primary environmental factors that influence metabolic rates of reef invertebrates. Changes of temperature and salinity can alter respiration rates and some behaviors of animals such as changes of movement and excretion. In this study, we investigated the effects of temperature and salinity levels on the oxygen consumption rates and behaviors of the nudibranch, Jorunna funebris (Kelaart, 1858). The results showed that the changes of both temperatures and salinity levels affected the oxygen consumption rates of the nudibranchs in all size classes. The results also showed that rates of oxygen consumptions of nudibranch increased with the increase or decrease of temperature and salinity levels. In addition, the temperature and salinity stresses caused nudibranchs inactive or more active than usual. More mucous secretion and increase of respiration rates were also observed.
