Is the skeleton an organ?

Bones are rigid organs that form part of the endoskeleton of vertebrates. They function to move, support, and protect the various organs of the body, produce red and white blood cells and store minerals. Other types of tissue found in bones include marrow, endosteum and periosteum, nerves, blood vessels and cartilage.

How many bones does a fish have?

Some fish (sharks and rays) don't have any true bones—their skeletal elements are made of cartilage. The number of bones in other fish species varies widely. Most fish actually have fewer bones than most other vertebrates (animals with backbones), including humans (who have 206 bones as adults).

Do skeletons have teeth?

Sometimes when skeletons are unearthed that have been in the ground for say 2000 years and they have some teeth, the teeth usually look in very good condition. After death however, teeth become the most durable part of the body, which explains why they are often found with ancient skeletons.

Why do we have a skeleton?

The skeleton is the body's framework. It is made of bones, which provide a firm surface for muscles to attach to, so that they can move. Without a skeleton, we would not be able to move at all. The skeleton also supports the body and protects our internal organs.

Why do animals need to move?

Animals move for a variety of reasons, such as to find food, a mate, a suitable microhabitat, or to escape predators. For many animals, the ability to move is essential for survival and, as a result, natural selection has shaped the locomotion methods and mechanisms used by moving organisms.

Why are the largest animals only found in water?

This is because the surface area of their lungs, intestines, red blood cells and kidneys becomes relatively smaller with increasing total body size. This means that above a certain point, big animals cannot grow organs that are able to handle the metabolic requirements of their giant bodies.”
