An external supportive covering of an animal (as an arthropod).
external skeleton; the hard skeleton that forms the external surface of some animals. The exoskeleton protects, supports, and provides a place for muscles to attach. Some mollusks, tortoises, and arthropods (such as crabs, lobsters, barnacles, and shrimp) have exoskeletons.
in Arthropods, the hardened cuticular covering of the body serving for protection of soft parts and as sites for muscle attachments.
the hard, protective, outer covering of arthropods and mollusks.
the protective or supporting structure covering the outside of some animals, such as crustaccans.
an external covering or integument, esp. when hard, as the shell of crustaceans (Stein 1966).
Some insects, arachnids, and crustaceans have a hard external 'shell' protecting their soft insides. This shell is called an exoskeleton.
a hard, external body covering that provides support for tissues and organs and protects the organism from predators. Arthropods have exoskeletons.
The hard external supporting skeleton of insects and other arthropods. It is secreted by epidermal cells.
the hard outer covering of an insect or other animal that has no bones inside. Exoskeletons don't grow, so ladybug larvae must shed old ones and grow new ones as they get bigger.
the external hardened skeleton of invertebrates.
(eks´ oh skel´ e ton) [Gr. exos: outside + skleros: hard] • A hard covering on the outside of the body to which muscles are attached. (Contrast with endoskeleton.)
a hard encasement on the surface of an animal such as an insect
A rigid, chitinous protective structure that surrounds the bodies of arthropods and provides support.
rigid or articulated envelope that supports and protects the soft tissues of certain animals, such as lobsters, crabs, spiders, and insects
Literally 'having the skeleton on the outside'. Organisms like insects do not have bones inside their bodies; instead their support structures are plates of tough materials like chitin or calcium carbonates that act like a 'suit of armour' on the outside. Inside, the muscles and organs are protected from any impact or damage. One problem with this is that the material of the exoskeleton is often so rigid, that as the animal grows it has to moult off the old exoskeleton and quickly grow a new - and larger - one to protect itself.
The outer covering of the insect that provides support.
n. An external, often hard, covering or integument that provides support and protection to the body.
an outside covering that protects the soft bodies of some invertebrates.

ex-o-SKEL-eh-ten A braced framework skeleton on the outside of an organism. 683
n. A hard external covering of various animals, including arthropods, that provides attachment for muscles and protects the animal from drying out and/or mechanical injury.
The hard outer covering that makes up the skeleton of insects and some other animals.
The hardened outer body layer of insects and other arthropods that functions both as a protective covering and as a skeletal attachment for muscles. For grit, Purple Martins feed their nestlings broken glass, metal fragments, quartz, sand, eggshell, and oystershell. This grit enables the nestling's gizzard to pulverize the armor-like exoskeletons of the beetles and other hard-bodied insects they are fed.
A skeleton on the outside of a creature's body (invertebrates, like insects & crayfish have exoskeletons)
a hard covering of a crustacean's body
The outer body covering that is made up of protein, chitin, and calcium. A crab that has molted will ingest it's exoskeleton as a source of calcium. EXO
The external body wall of arthropods.
An external supportive covering of an animal, which may be composed of any or a variety of different materials. Exoskeletons are most often found in animals that lack an internal skeleton.
An exoskeleton is a hard outer structure, such as the shell of an insect or crustacean, that provides protection or support for the organism.
an external, supportive covering on the outside of an animal, as in all arthropods including insects.
a tough protective outer body covering, as found in the crustaceans like our hermit crab.
An external skeleton of an animal, serving as a protective and supportive covering for its softer parts; e.g. the outer shell of a brachiopod or pelecypod, the system of sclerites covering the body of an arthropod, or the bony plates covering an armadillo.
A hard, jointed, external covering that encloses the muscles and organs of an organism; typical of many arthropods including insects.
Any hard outer covering that protects or supports the body of an animal. (SS)
Hard external shell covering the pupa or adult
a skeleton on the outside of the body
(noun) - a tough, external covering made of chitin, which supports the body and protects the internal organs.
The external protective or supporting structure of many invertebrates, such as insects or crustaceans.
external, outside protective or supporting structure of many invertebrates; typically a hardened skin that must be shed to grow
eK-Soh-skell-eh-ton) An exterior skeleton. The human skeleton, our bones, for example, are within our bodies. Whereas many insects, carry their structure externally, which affords them physical protection.| Menu
the hardened integument of the insect that provides support for the muscles and body; literally an outer skeleton.
An external skeleton. The hard body covering or shell of most invertebrate animals, including insects, crayfish, and mil-lipedes.
outer covering of arthropods."shell".
Chitinous external skeleton of insects and other arthropods.
External skeleton of the body of an insect.
a hard body covering found on the outside of many invertebrates. The term is most often applied to the body covering on arthropods. This is made of a protein compound which is secreted by a layer of cells underneath it. Because it is not stretchy, the creature has to moult regularly to accommodate growth.
A skeleton present on the outside of an organism, as in Arthropods or Mollusks.
external, outside protective or supporting structure of invertebrate
(ek - soh - skel - i - ton) An external protective or supportive covering of many invertebrates, including horseshoe crabs. The carapace forms part of the horseshoe crabís exoskeleton.
outer hard part of an insect, including legs & wings
a hard protective covering, serving the purpose of a skeleton on the outside of an animal's body; such as insects, spiders, ticks, centipedes, millipedes, crayfish, lobsters, mites, scorpions, etc.

An exoskeleton is a tough, structural body armor made of chitin. Crustacean s have exoskeletons.
The protective outer shell belonging to creatures such as insects, crustaceans and spiders.
An external skeleton, such as the shell of a mollusk or arthropod.
The hard outer surface of some animals, which is the skeleton.
An exoskeleton is a tough, structural body armor made of chitin. Arthropods (insects, arachnids, trilobites, crustaceans, etc.) have exoskeletons.
A hard supporting structure on the outside of the body, enclosing all living cells ("external skeleton").
(1.) A rigid framework inside which an organism's other components are contained. Examples include mollusks and insects, who are invertebrates (literally, spineless). Mammals and reptiles are vertebrates with interior skeletons. (2.) A mechanical device that amplifies the strength of the user, who stands or sits in an open cabin. Such devices typically have two arms and/or two legs so that their operation is more intuitive.
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. Lobsters, for example, have tough outer shell systems which provide rigidity and shape to their bodies, in addition to an endoskeleton.
