Humans and crocodiles have endoskeletons
Yes, it is.
A endoskeleton is the internal skeleton of an animal. Since a cat's skeleton is on the inside of its body, it has a endoskeleton.
= an internal support structure of an animal = (got it from wikipedia)
A cheetah has an endoskeleton, which is an internal skeleton.
Sea Cucumbers.
The antonym of exoskeleton is endoskeleton. An endoskeleton is an internal skeleton found in vertebrates, whereas an exoskeleton is an external skeleton found in arthropods and some other invertebrates.
It is the calcium-rich system of bones that supports the animal's body.
Endoskeleton, it is a mammal, and no mammals have exoskeletons. You'll find that most animals in the insects and arachnids section of the animal groups, do however. the exoskeletons on insect are often mistaken for a "shell" of the animal.
It gives it support rather than protection.
Endoskeleton
Endoskeleton - their bones are inside their body
Amphibians have endoskeletons because their skeletons are inside their bodies. Exoskeleton animals have their skeletons on the outside: such as crabs, lobsters, insects, ect. (Basically an exoskeleton animal "crunches" when it is stepped on. Weird, I know but it will help you remember.) :)
