An exoskeleton, in contrast to an endoskeleton, is an external anatomical feature that supports and protects an animal's body. All arthropods (such as insects, spiders and crustaceans) and many other invertebrate animals (such as shelled mollusks) have exoskeletons.

What is an example of an animal with an exoskeleton?
Examples. Woodlice, Ants and Crabs are common examples of animals with exoskeletons, and exoskeleton animals can vary greatly across these species.
What is exoskeleton and endoskeleton?
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.
Is there a mammal with an exoskeleton?
Armadillos are terrestrial mammals and, therefore, have an endoskeleton inside their body. However, these animals are also characterized by having an outer shell formed of bony plates, which serves as a means of protection.
Is a turtle an exoskeleton?
The turtle shell isn't like any other protective element of any living animal: it's not an exoskeleton, like some invertebrates have, nor is it made of ossified scales like armadillos, pangolins, or some snake and reptile species. ... The turtle shell is actually a peculiar evolution of a turtle's bone structure.
How do you explain exoskeleton to a child?
An exoskeleton is a hard covering that supports and protects the bodies of some types of animals. The word exoskeleton means “outside skeleton.” Many invertebrates, or animals without backbones, have exoskeletons. Insects are the largest group of animals that have an exoskeleton.
Where would you find an exoskeleton?
An exoskeleton is the rigid covering found on the exterior of many animals, particularly invertebrates such as arthropods and mollusks. Much like the internal endoskeleton of vertebrates, the exoskeleton is responsible for supporting the structure of an animal's body.
Are crabs exoskeleton?
Crabs, lobsters, shrimp, barnacles and many other animals belong to the phylum arthropods. ... All arthropods have a hard exoskeleton made of chiton, a type of protein. This shell provides protection for the animals, and gives support for the attachment of the arthropod's muscles.
What is exoskeleton explain with example?
Exoskeletons are the hard coatings on the outside of some animals, mostly arthropods. They are nonliving, made of chitin and calcium carbonate. ... Examples of animals with exoskeletons are grasshoppers, cockroaches, ants, bees, scorpions, cicadas, lobsters, shrimp, black widows, snails, and crabs.
What is exoskeleton made up of?
The exoskeleton is composed of a thin, outer protein layer, the epicuticle, and a thick, inner, chitin–protein layer, the procuticle. In most terrestrial arthropods, such as insects and spiders, the epicuticle contains waxes that aid in reducing evaporative water loss.
Do all invertebrates have an exoskeleton?
Invertebrates can have a skeleton outside their bodies called an exoskeleton, while some invertebrates have no skeleton at all! In fact, the majority of animals on Earth are invertebrates. ... Insects, spiders and shellfish are some of the invertebrates that have exoskeletons.
How does exoskeleton give the animal shape?
Terrestrial animals tend to have body shapes that are adapted to deal with gravity. Exoskeletons are hard protective coverings or shells that also provide attachments for muscles. ... The exoskeleton must increase thickness as the animal becomes larger, which limits body size.
Does a spider have an exoskeleton?
Spiders are invertebrates. That means that they don't have a skeleton like we do. Instead they have an exoskeleton. This is a hard, protective outer layer made of overlapping layers of chitin (a natural polymer) and protein.
What is the purpose of exoskeleton?
The exoskeleton (shared with other arthropods) provides protection against predation and desiccation or waterlogging (necessary for small organisms) and innumerable points of muscle attachment (for flexibility). However, the exoskeleton also limits the size attainable by arthropods.
