WARM AND COLD-BLOODED ANIMALS BY JASON 2006 Lizard Ducks
What is the difference between warm and cold-blooded animals ? Cold-blooded animals’ body temperature depends on how cold or warm the temperature is around them. Cold blooded animals often like to bask in the sun to warm up. Some insects die when it gets too cold, however others survive by migrating to warmer areas or underground. Marine Iguana Warm-blooded creatures, like mammals and birds, can keep the inside of their bodies at a constant temperature. They do this by cooling themselves when they are in a hotter environment. Alligator
How the environment affects a cold-blooded animal’s bodytemperature. What does it mean when cold-blooded creatures take on the temperature of their surroundings? It means that their body temperature depends on the temperature surrounding them. Example: They are hot when their environment is hot and cold when their environment is cold. Cold-blooded animals are more active in warm environments then in cold environments. They are sluggish in cold environments. Snake
What does it mean to be cold blooded or warm blooded? The temperature of an animals blood is related to its body temperature. Honeybees stay warm by moving their wings and crowding together to generate heat. Some cold blooded animals, such as bees or dragonflies, shiver to stay warm when in a cold environment. Bees
Warm-blooded animals can remain active in cold environments in which cold-blooded animals can hardly move. Warm-blooded animals can live in almost every surface environment on Earth, like in artic regions or on high mountains where most cold-blooded animals would have difficulty surviving.Warm-blooded animals can remain active, seek food and defend themselves in a wide range of outdoor temperatures. Cold-blooded animals can only do this when they are warm enough. Example of a cold-blooded animal Toad
How warm-blooded animals can cool down. Large animals such as elephants have difficulty cooling down. To stay cool, warm blooded animals sweat or pant to loose heat by water evaporation. They can also cool off by moving into a shaded area or by getting wet. Only mammals can sweat. Primates, such as humans, apes and monkeys, have sweat glands all over their bodies. Dogs and cats have sweat glands only on their feet. Elephants
Whales are mammals who have no sweat glands, but then since they live in the water, they don’t really need them. Large mammals have difficulty cooling down if they get over heated. This is why elephants, for example, have large, thin ears which loose heat quickly. Mammals have hair, fur or blubber, and birds have feathers to keep it warm. Whales Many mammals have thick layers of fur, which keep them warm in the winter.
