Cartilage
Animal parts that are soft and don't have a skeleton leave the worst imprints. Fossils are made with animal parts that are hard and durable.
A splanchnic bone is a bone that develops in soft tissue and is unattached to the rest of the skeleton. Ex. In cats and dogs: Os penis (a bone in the penis) In cattle: Os cordis (a bone in the heart)
the koalas skeleton is soft.
Yes. All soft body parts do. Eventually, only the skeleton remains.
the calcium in it protacts the soft part of the shell and its light weght like the spongy in a bone
The human skeleton is primarily made of bone tissue. Bones are composed of collagen, a protein that provides flexibility and strength, and mineral deposits such as calcium and phosphorus that make them hard and rigid. The skeletal system plays a crucial role in providing support, protection for vital organs, and facilitating movement.
they don't have skin, their body is made mostly of water. It is basically a thin layer of cells and that's it.
The exoskeleton. See the related link for more information.
Pigs do not have a soft skeleton. Like other mammals, they have an internal skeleton of calcified bones for support.
Humans have endoskeletons, which means their skeletons are contained within their bodies, and mostly made of bones. This is in contrast to exoskeletons, which are the outer shelling of the creature and made of more flexible material.

Not exactly. They have what is called an exoskeleton, which means a skeleton on the outside. The shell or carapaceof a bug is its skeleton.
