Question

Quizplus · Accepted Answer

Sea stars are ectothermic and do not have the ability to adjust their body temperature through behavior, since they are marine invertebrates and are subject to the temperature of their surrounding water. Terrestrial lizards and hummingbirds are also ectothermic organisms, but they have the ability to behaviorally adjust their body temperature by seeking shade or sun, or by regulating their metabolic rate through activity levels. Bluefin tuna are endothermic, meaning they can generate their own heat, and honeybees in a hive can regulate their temperature through collective behavior.
