a hydrostatic skeleton
A grasshopper's skeleton is external and is called an exoskeleton. It is made of a substance called chitin and does not contain bones. A human's skeleton is internal and in an adult contains 206 bones.
A pigeon has an endoskeleton, which is an internal skeleton made of bones.
spongin!
they don't have skin, their body is made mostly of water. It is basically a thin layer of cells and that's it.
In an embryo, the skeleton is originally made of cartilage. This cartilage gradually mineralizes and ossifies into bone in a process called endochondral ossification.
A skeleton made of fluid is called a hydrostatic skeleton. This type of skeleton is found in many soft-bodied invertebrates, such as jellyfish and earthworms, where the body is supported by fluid pressure within a closed body cavity. The hydrostatic pressure allows these organisms to maintain their shape and facilitate movement through muscle contractions.
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.

Dolphin skeletons are not made of bones like most mammals. Instead their skeleton is made of a tough, flexible tissue called cartilage. It is the same thing that human ears are made of.

Blood contains the most water, comprising about 90% of its composition. The brain is also largely composed of water, with around 75% of its weight being water. In contrast, the skeleton is made up of bone, which contains only about 20% water. Therefore, blood has the highest water content, followed by the brain, and then the skeleton.
