An exoskeleton is a hard external skeleton that protects the outer surface of an organism and enables movement through muscles attached on the inside. An endoskeleton is an internal skeleton composed of hard, mineralized tissue that also enables movement by attachment to muscles.

What skeleton is an external skeleton?
Exoskeletons are external skeletal systems that are made up of chitin and calcium carbonate. Organisms with an endoskeleton are supported by a hard, mineralized skeletal system that resides inside the body. In vertebrates, the endoskeleton system is further divided into the axial skeleton and appendicular skeleton.
What are internal skeletons called?
An endoskeleton (From Greek ἔνδον, éndon = "within", "inner" + σκελετός, skeletos = "skeleton") is an internal support structure of an animal, composed of mineralized tissue.
What is endoskeleton and exoskeleton?
An exoskeleton is a hard external skeleton that protects the outer surface of an organism and enables movement through muscles attached on the inside. An endoskeleton is an internal skeleton composed of hard, mineralized tissue that also enables movement by attachment to muscles.
Which animal has both endoskeleton and exoskeleton?
Tortoises have an adaptation called a shell which is modified into a rib cage, sternum. The shell is the outer layer which protects them from the predators. The shell acts as an exoskeleton for tortoises. So the tortoise contains both exoskeleton and endoskeleton.
What type of skeleton do worms have internal or external?
Earthworms do not have an internal skeleton as we do, and they do not have a protective hard exoskeleton as does an insect. They are flexible, long bundles of muscle, especially designed for life underground.
Is a prawn endoskeleton or exoskeleton?
Exoskeleton: The stable chitinous or mineralised outer shell of an organism, for example, the shell of a grasshopper or prawn. Endoskeleton: A cartilaginous or mineralized support structure inside the body, for example, in humans and other vertebrates.
Do amphibians have an endoskeleton or exoskeleton?
Mammals, reptiles, birds, fish and amphibians are vertebrates with endoskeletons (skeletons inside their bodies). Their skeletons provide support and protection and help them to move. Insects, spiders and shellfish are some of the invertebrates that have exoskeletons.
What are the roles of the endoskeleton?
Endoskeletons provide support for the body, protect internal organs, and allow for movement through contraction of muscles attached to the skeleton.
Which of the following animal is supported by endoskeleton?
Answer: Deer is the answer. Explanation: Hope this helps you.
Which of the following has a cartilaginous endoskeleton?
Thus, we can say that the endoskeleton which is made up of cartilaginous is present in the group of Elasmobranchii. So, the correct answer is Elasmobranchii.
What is endoskeleton and examples?
The definition of an endoskeleton is the internal bone or cartilage structure of animals which have a vertebra and some animals without vertebra. An example of an endoskeleton is the skeleton inside a human body. ... Certain invertebrates, such as sponges and echinoderms, also have endoskeletons.
What is the difference between hydrostatic skeleton exoskeleton and endoskeleton?
An endoskeleton is a hardened internal skeleton. An exoskeleton is a hard external framework. A hydrostatic skeleton, or hydroskeleton, is a kind of skeleton that is composed of soft tissue filled with an incompressible fluid or gel-like substance. Along with insects, mollusks and crustaceans have exoskeletons as well.
What are the 2 basic types of skeletons?
The adult human skeleton usually consists of 206 named bones. These bones can be grouped in two divisions: axial skeleton and appendicular skeleton.
