yes they do
Mammals, birds, reptiles, amphibians, and some fish have endoskeletons. An endoskeleton is an internal support structure made of bone or cartilage that provides structural support, protects internal organs, and allows for movement.
Vertebrates have endoskeletons. E.g. humans, birds, fish, etc...
The endoskeleton is an internal skeleton. Human beings and other mammals have endoskeletons. Basically, any animal with their bones on the inside has an endoskeleton.
Animals with endoskeletons include humans, fish, birds, and mammals. Endoskeletons provide internal support and protection for the body's soft tissues, muscles, and organs.
Endoskeletons are located inside an organism. Exoskeletons are located on the outside of an organism, like a shell. Both are used for structure and protection.
Yes
No. They have an endoskeleton just like us.

Some in the Precambrian Super Eon, but mostly hard parts came along in the Cambrian period at about 540 mya (Million Years Ago)
Yes, they have endoskeletons. Seahorses' skeleton are inside their bodies so they would have endoskeletons.
Lions have endoskeletons because they are mammals and we are mammals.

What materials make up the endoskeletons of most vertebrates
we need endoskeletons because they hold us up. if we had an exoskeleton we would be covered by a shell
