What is an cold blooded animal?

Answer 1

Cold Blooded just means that the animal is unable to maintain a constant body heat. Reptiles and other cold blooded animals need to be given some type of heat in order to maintain proper body function

Answer 2

Cold-blooded creatures take on the temperature of their surroundings. They are hot when their environment is hot and cold when their environment is cold. In hot environments, cold-blooded animals can have blood that is much warmer than warmblooded animals.

Cold-blooded animals are much more active in warm environments and are very sluggish in cold environments. This is because their muscle activity depends on chemical reactions which run quickly when it is hot and slowly when it is cold.

A cold-blooded animal can convert much more of its food into body mass compared with a warmblooded animal.

Cold-blooded animals often like to bask in the sun to warm up and increase their metabolism. While basking, reptiles will lie perpendicular to the direction of the sun to maximize the amount of sunlight falling on their skin. They will also expand their rib cage to increase their surface area and will darken their skin to absorb more heat. When a reptile is too hot, it will lie parallel to the sun's rays, go into a shady area, open its mouth wide, lighten its skin color or burrow into cool soil.

Some cold-blooded animals, such as bees or dragonflies, shiver to stay warm when in a cold environment. Fish who live in areas where the winters are cold move to deeper waters during the colder months or migrate to warmer waters. Some fish have a special protein in their blood which acts like anti-freeze to help them survive very cold water temperatures.

Snakes, lizards, toads, frogs, salamanders and most turtles will hibernate during cool winters. Some insects die when it gets too cold, however others survive by migrating to warmer areas or moving underground.

Honeybees stay warm by crowding together and moving their wings to generate heat.

A cold-blooded animal's level of activity depends upon the temperature of its surroundings. A reptile, for example, will increase its body temperature before hunting and is better able to escape predators when it is warm. Cold-blooded animals also need to be warm and active to find a mate and reproduce.

Cold-blooded animals require much less energy to survive than warmblooded animals do.

Some animals do not fall neatly into the categories of being warm or cold-blooded. Bats, for example, are mammals who cannot maintain a constant body temperature and cool off when they are not active. Echidnas maintain a range of body temperatures which usually lies between 77 and 98.6 degrees Fahrenheit and have difficulty cooling down. Mole Rats are another group of mammals who are unable to regulate their body temperature, however, since they live underground, the temperature of their environment does not change much. Some warmblooded animals, such as bears, groundhogs, gophers and bats hibernate during the cold winter. During hibernation these animals live off of stored body fat and can drop their body temperatures by as much as 50 degrees Fahrenheit. The Hawk Moth is an insect which can raise its body temperature well above the temperature of its surroundings when it is flying because of its huge wing muscles which generate heat when in use. Bees are another example of insects that can raise their body temperatures above that of their environment by moving their wings rapidly to generate heat.

Answer 3

A "cold-blooded" organism (really called an endotherm) is any organism that requires the environment to provide it with body heat. Lizards are a great example (when they bask in the sun on rock in the morning, they are heating up).

Answer 4

It means that they don't have thermogenic cells un-like mammals they don't have the abality to keep warm ergo if you put a snake in a freezer it won't die but it will go into hibernation then if you put it in a pot of hot water it will wake from its sleep

Answer 5

the definition for cold blooded is that you are evil and lonely and don't like people.
cold blood is a idiom which means " In a cruel way"

Answer 6

Reptiles, such as snakes and lizards, are cold blooded.

Answer 7

It means body temperature that changes according to the temperature of the surroundings like fish, lizards, turtles, and reptiles.

Answer 8
