Whales, dolphins and porpoises are marine mammals of the order Cetacea. Because they live in water all the time, they do not have sweat glands.
How do lizards cool off?
For most lizards and snakes, cooling down is as easy as moving into the shade or hiding under a rock , said Jack Conrad, a research associate at the American Museum of Natural History in New York and a specialist in reptile biology. Reptiles warm up just as simply, by basking in the sun.
Do lizards sweat?
Their metabolism depends on the temperature of their environment. Unlike birds and mammals, reptiles do not maintain a constant internal body temperature. Without fur or feathers for insulation, they cannot stay warm on a cold day, and without sweat glands or the ability to pant, they cannot cool off on a hot one.
What happens if a lizard overheats?
If the lizard gets too hot, he will move into the shade or a burrow to cool off . Some lizards have adapted to be able to change color. If a lizard turns a darker color, he will be able to absorb heat better than when he is a lighter shade.

What is the sweatiest animal on earth?
Perhaps the most unusual sweat in the animal kingdom comes from hippos. A research team from Kyoto Pharmaceutical University recently determined that the oily substance, containing orange and red pigments, is antibacterial, prevents sun damage and regulates temperature.
Do animals cry?
If you define crying as expressing emotion, such as grief or joy, then the answer is yes. Animals do create tears, but only to lubricate their eyes , says Bryan Amaral, senior curator of the Smithsonian's National Zoo. Animals do feel emotions, too, but in nature it's often to their advantage to mask them.
Can a lizard overheat?
Thermoregulation is the process cold-blooded lizards use to maintain their body temperature. Lizards warm themselves using insolation and conduction. ... If the lizard gets too hot, he will move into the shade or a burrow to cool off. Some lizards have adapted to be able to change color.

How hot can a lizard get?
Many species do like it hot, with some monitor lizards basking at temperatures of 120–150 F. I'd certainly call that some warm blood! When at their ideal body temperature (also called thermal optimum), they have metabolisms that function near or exceeding the level of many birds!
Are humans the smartest animal?
Strictly speaking, humans are the smartest animals on Earth —at least according to human standards. ... Measuring the intelligence of animals can be difficult because there are so many indicators, including the ability to learn new things, the ability to solve puzzles, the use of tools, and self-awareness.
Are humans the only animals that blush?
Humans are the only species known to blush , a behavior Darwin called “the most peculiar and the most human of all expressions.” It remains uncertain why people blush, involuntarily revealing our innermost emotions (we do know how it works).
Can humans outrun any animal?
Most mammals can sprint faster than humans — having four legs gives them the advantage. But when it comes to long distances, humans can outrun almost any animal . Because we cool by sweating rather than panting, we can stay cool at speeds and distances that would overheat other animals.
Do animals have periods?
It turns out, menstruation is quite rare in the animal kingdom , even amongst mammals. Other primates menstruate (though not as heavily as humans do), as do some species of bats and elephant shrews. That's it.
What does sweat like a pig mean?
As the iron cools, the surrounding air reaches its dew point, and beads of moisture form on the surface of the “pigs”. “Sweating like a pig” indicates that the “pig” (ie iron) has cooled enough to be safely handled.
Which animal sweat Colour is pink?
HIPPOS spend most of their day resting in water and can hold their breath for up to 30 minutes. Hippos secrete a reddish oily fluid sometimes called “blood sweat” from special glands in their skin.
