exoskeleton usally only found in insects
Invertebrates are animals without backbones, such as worms, shellfish, and in almost all vertebrates, bone gives the skeleton its strength.

The name that is given to animals that cannot make their own body heat is called a warm blood animal.
An ant
An animal that has no internal skeleton is called an invertebrate. Invertebrates need to have other ways to propel them through the water, or on land. A worm, for example has to squirm or make an "S" shape to move.

What is my name?
Snake and earthworm are the 2 animals that move with their body.
Actually lobsters skeletons are do on the outside in order to fight off natural predators such as the hippopotamus (latin name unknown) whose mouths can open to 150 degree angles. The lobster has a very small mouth only opening to about three millimeters for to use their armored bodies to defend against such voracious attacks.
In animals with external testes, the sack is generally known as the scrotum. It holds the spermatozoa outside of the main carapace or thorax in order to maintain their optimum fertility temperature, often a few degrees lower than the body's optimal temperature, hence they are external.
If it is outside the female body, it is called in vitro fertilization. If it occurs outside the uterus it is called an ectopic pregnancy.

Cold blooded animals cannot regulate their own body temperature. Therefore, it changes with their environment.
warm animals Mammals
Endotherms or homeotherms are animals that can produce their own body heat through internal processes such as metabolism. They are able to regulate their body temperature independently of the external environment.
Semen
One obvious function of the skeleton is to provide stability. If people and animals didn't have skeletons, we'd all be quivering piles of skin, muscle, and hair.
