Detailed explanation-1: -The hard part which is the internal support of the structure is called an endoskeleton. It is developed from endoderm and is called a living structure. Some examples of endoskeleton are cartilage, bone, etc. The hard part present outside the body which protects the soft tissues and muscles is called the exoskeleton.

Detailed explanation-2: -Organisms like tortoise and crocodile posses both exoskeleton and endoskeleton. Tortoise has an outer hard shell and a skeleton inside the body. The crocodile has a tough leathery skin/hide on the outside and then a skeleton inside the body.

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: -An exoskeleton is a key feature of arthropods, a category of animals that includes insects, spiders, and crustaceans. Grasshoppers, cockroaches, ants, bees, cicadas, scorpions, lobsters, shrimp, black widows, snails and crabs are all examples of animals with exoskeletons.

Detailed explanation-5: -Explanation: Endo and exo skeletons are both skeletal structures that have a similar purpose: to 1) support the organism that it’s in 2) provide protection to important organs or body parts and 3) give the organism structure so it can preform the tasks it needs to survive.
