The aquatic organisms in which the osmotic concentration and temperature of body change according to ambient conditions of water are called conformers. About 99 percent of animals and nearly all plants are included in the category of conformers, which do not have a mechanism to maintain a constant internal body environment. Their body temperature change with the surrounding temperature. On the other hand, some organisms (e.g., birds and mammals) are able to maintain a constant body temperature and constant osmotic concentration despite changes in the external environment. They are called as regulators. They perform homeostasis mostly through thermoregulation and osmoregulation by physiological or behavioural means.
