What animals use ectothermic?
The ectotherms include the fishes, amphibians, reptiles, and invertebrates. The body temperature of an aquatic ectotherm is usually very close to the temperature of the surrounding water.
Are seahorses endothermic or ectothermic?
Seahorses are endothermic because they live in the sea (under water).
Are otters endothermic?
Sea Otters are mammals because they produce their own body heat (endothermic), have fur, give live birth, have mammary glands that produce milk for mothers to feed their babies, and have a complex brain.
What animals are endothermic and ectothermic?
Animals 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 water, but unlike a true endotherm, they don’t maintain a specific body temperature.
Is a rattlesnake an endotherm or ectotherm?
Endotherms and ectotherms People, polar bears, penguins, and prairie dogs, like most other birds and mammals, are endotherms. Iguanas and rattlesnakes, like most other reptiles—along with most fishes, amphibians, and invertebrates—are ectotherms. Endotherms generate most of the heat they need internally.
How do ectotherms regulate their body temperature?
Most ectotherms do regulate their body temperature to some degree, though. They just don’t do it by producing heat. Instead, they use other strategies, such as behavior —seeking sun, shade, etc.—to find environments whose temperature meets their needs.
Why do endotherms have a higher metabolic rate than ectotherms?
One other important point: as a general rule, endotherms have considerably higher metabolic rates than ectotherms. That’s because they have to burn large quantities of fuel—food—to maintain their internal body temperature. Why regulate temperature?
