Question

Quizplus · Accepted Answer

Marlins and brown bats are both capable of generating their own heat, making them endothermic. Marlins, like other large fish, can generate heat through their muscles to keep their eyes and brain warm, enhancing their hunting abilities in cold waters. Brown bats, as mammals, maintain their body temperature through metabolic processes, allowing them to stay active in various temperatures. Lizards, on the other hand, are ectothermic and rely on external heat sources to regulate their body temperature.
