Are all fish endotherms? The endotherms primarily include the birds and mammals; however, some fish are also …
WebAnimals that hibernate, for instance, are endothermic when they are active but resemble ectotherms when they are hibernating. Large fish like tuna and sharks generate and conserve enough heat to raise their body temperature above that of the surrounding … Each of the categories above is called a trophic level, and it reflects how many … WebMechanisms of thermoregulation. As a refresher, animals can be divided into endotherms and ectotherms based on their temperature regulation.
