harks do sleep, but not in the same way that humans do. Sharks’ sleep can be divided into a less active and deep slumber. Sharks that can’t stop swimming move into a rest period characterized by reduced activity. On the other hand, sharks with spiracles can fall asleep quickly since they can stop swimming if they want to.

Cats do sweat, even if we rarely notice them doing so. However, they do not sweat as much as many other mammals do. In fact, cats only sweat a small portion of what humans do. But, similar to humans, cats also sweat when they get too hot as a way to regulate their body temperature.

Underwater, crocodiles are unable to breathe. This is because they lack the gills that fish have. However, when fully submerged, they can hold their breath underwater for a considerable time. They can also float while breathing by sticking only the tip of their nose above the surface.

Crocodiles typically take a rest on the ground near the shore. Crocs in captivity usually rest on concrete made by humans. Crocodiles may also be seen dozing off while partially submerged in water.

Depending on the species, sharks may or may not have razor-sharp teeth. Yet, sharks and razor-sharp teeth are almost always synonymous. This is because these predators would be impossible to imagine without teeth. And there are numerous interesting facts about shark teeth.

Baleen whales are the largest whales, and humpback whales are baleen whales. It means that humpback whales do not possess teeth. Instead, they possess baleen plates that resemble a comb.

Whales have tail fins. Whale tails, however, differ significantly from the tails of other fish, including sharks. A whale’s tail has two lobes called flukes that move up and down rather than side by side and are separated by a deep cleft. Furthermore, rather than bones, the flukes are composed of dense, fibrous connective tissue.
