Is a shark endothermic or ectothermic?

Marine mammals are endothermic, meaning their body temperature is constant and created internally. Most sharks, like most fishes, are ectothermic – their body temperature matches the temperature of the water around them. There are some sharks that have endothermic capabilities, though.

Is a great white shark an animal or a fish?

Similarly, great whites are sharks, and sharks are fish, and fish are animals. Think of evolution as a great tree of life — a very common and illuminating metaphor that goes back at least to Darwin. At each branch, two descendents issue from a common ancestor — for example, dinosaurs and pterosaurs split about 230 million years ago.
