Are manatees endothermic

No, manatees are not endothermic; they are ectothermic animals. This means that they rely on external sources of heat to regulate their body temperature rather than generating heat internally like endothermic animals do. Manatees are adapted to warm aquatic environments, and they can experience stress in colder waters. They often seek warmer areas, such as springs or shallow coastal waters, to maintain their body temperature.
