Endoskeleton
From wikipedia
An endoskeleton is an internal support structure of an animal, composed of mineralized tissue. Endoskeleton develops within the skin or in the deeper body tissues. The vertebrate is basically an endoskeleton made up of two types of tissues (bone and cartilage). During early embryonic development the endoskeleton is composed of notochord and cartilage. The notochord in most vertebrates is replaced by vertebral column and cartilage is replaced by bone in most adults.In three phyla and one subclass of animals, endoskeletons of various complexity are found: Chordata, Echinodermata, Porifera, and Coleoidea. An endoskeleton may function purely for support (as in the case of sponges), but often serves as an attachment site for muscle and a mechanism for transmitting muscular forces. A true endoskeleton is derived from mesodermal tissue. Such a skeleton is present in echinoderms and chordates.

∙ 13y agothere are two types of skeletons: endoskeleton, which is when the skeleton is on the inside, and there's exoskeleton, which is when the skeleton is on the outside.
some animals with endoskeletons are: cats, dogs, hippos, horses; pretty much any animal you can think of. some with exoskeletons are: crabs, lobsters, and scorpians.
