a skeleton that is on the outside and encases all the muscles and organs of an organism. Read more on: Exoskeleton

A supporting structure secreted by ectoderm or epidermis; external, not enveloped by living tissue, as opposed to endoskeleton. experience

 the hard, external body shell of arthropods. It is made of a stiff material called the cuticle, which has many layers. The cuticle is the building material of the entire body surface, the joint membranes, tendons, apodemes, sensory hairs, and even the lining of the respiratory and reproductive organs. Apart from those structural functions, the cut [..]

(n) the exterior protective or supporting structure or shell of many animals (especially invertebrates) including bony or horny parts such as nails or scales or hoofs

the harder outer body layer of an insect or arthropod. Grit helps birds pulverize this part.

A skeletal structure outside the body, as in insects.

A skeleton external to the remainder of the body, the muscles attaching to its inner surface. Extrinsic:

rigid or articulated envelope that supports and protects the soft tissues of certain animals

outer hard part of an insect, including legs & wings

 (noun) - a tough, external covering made of chitin, which supports the body and protects the internal organs.

An external skeleton that supports and protects an animal's/insect's body.

Refers to the sclerotized integument which serves mechanically as a skeleton.

the outer portion of an insect body which may be relatively soft like a caterpillar or hardened like many beetles

  The hard outer shell that covers an insect’s body. Eyespots:

The supporting structure of an organism when it is on the outside of the body. Insects, crustaceans, and spiders all have exoskeletons. Birds, mammals, and reptiles have "endoskeletons," mea [..]

  The rigid external covering for the body of stag beetles, providing both support and protection.

a hard skeleton located on the outside of an invertebrate’s body (in contrast to the internal skeleton of vertebrates) that protects it and serves as a point for muscle attachment.

The segmented external skeleton (skin) of insects and other arthropods.

the hard, tough outer covering of insects and other arthropods

an ant's outer covering; a protective covering, like armor; it is the exoskeleton that is molted

an external skeleton, a tough structural body armour made of chitin. Arthropods such as insects, arachnids and crustaceans have segmented exoskeletons.

hard structure developed on the outside of, and giving support to, a body, such as the chitinous covering of an insect (Glossary of PM)

rigid or articulated envelope that supports and protects the soft tissues of certain animals, such as lobsters, crabs, spiders, and insects expressed genes

An external supportive covering of an animal such as a crab or insect (as an arthropod).

Hard outer shell that provides an invertebrate with support and protection. Blue crabs and other crustaceans have exoskeletons.

The outer support structure of an insect.

The covering of an arthropods body made of tough, protective and waterproof material.

The external skeleton that supports and protects an animal’s body in contrast to the bones of an internal skeleton. Rehabilitation engineers have used this design in nature to develop exoskeletons tha [..]

(anatomy) A hard outer structure that provides both structure and protection to creatures such as insects and Crustacea.

A hard encasement on the surface of an animal, such as the shells of mollusks or the cuticles of arthropods, that provides protection and points of attachment for muscles.

the hard external shell or covering of some animals.

n. An external, often hard, covering or integument that provides support and protection to the body.

The outer support structure of an insect.

An exoskeleton is a tough, structural body armor made of chitin. Arthropods (insects, arachnids, trilobites, crustaceans, etc.) have exoskeletons.

External skeleton; the shell of a crustacean

a skeleton covering the outside of the body, or lying in the skin, and supporting and protecting the soft body parts. Many invertebrates have exoskeletons (insects, starfish). Most higher organisms ha [..]

lightweight body covering that protects and supports an arthropod’s body, prevents it from drying out, and is shed by molting; a hard outer covering. exosphere -

A hard outer structure, such as the carapace of a lobster or crab, that provides protection or support for an organism (especially invertebrates).

A hard supporting structure on the outside of the body, enclosing all living cells (external skeleton).

Meaning 'outside skeleton,' it refers to certain animals' hard outer bodies. For example, many insects have a hard skin called an exoskeleton. The exoskeleton does not grow; it must be molted. Crabs, lobsters, and tarantulas have exoskeletons, too.
