Endoskeleton:
- It forms an internal body framework.
- This is a type of skeleton characteristic of all vertebrates.
- The endoskeleton is made of cartilage, bone or both.
- It is made up of living tissues and grows steadily as animal grows.
- Muscles are attached on the skeleton.
- The muscles are connected to bones by ligaments.
Functions
- The functions of endoskeleton include support, protection and movement.
- Locomotion in a finned fish e.g. tilapia.
- Most of the fishes are streamlined and have backward directed fins to reduce resistance due to water.
