Detailed explanation-1: -An animal with an endoskeleton has its size determined by the amount of skeletal system it needs in order to support the other tissues and the amount of muscle it needs for movement. As the body size increases, both bone and muscle mass increase.

Detailed explanation-2: -Endoskeletons forms an internal frame, which is able to support greater body weights against the downward pull of gravity. This enables vertebrate organisms to grow much larger sizes than those with external skeletons, such as insects.

Detailed explanation-3: -Endoskeleton is an internal skeleton that provides support and protection to the body’s organs while Exoskeleton is an external skeleton which provides protection to the body from outside. Endoskeleton is found within the human body while Exoskeleton works external to the human body.

Detailed explanation-4: -Endoskeletons are lighter, grow with the animal and have stong weight bearing properties. These enable animals to grow to larger sizes. Endoskeletons allow for faster movement than exoskeletons but the muscles are less flexible than an animal with a hydrostatic skeleton.
