Exempel på hur man kan använda EXOSKELETON i en mening

• Since the cuticle of these animals typically forms a largely inelastic exoskeleton, it is shed during growth and a new, larger covering is formed.
• There are several types of skeletons, including the exoskeleton, which is a rigid outer shell that holds up an organism's shape; the endoskeleton, a rigid internal frame to which the organs and soft tissues attach; and the hydroskeleton, a flexible internal structure supported by the hydrostatic pressure of body fluids.
• Other animal coverings, such as the arthropod exoskeleton, have different developmental origin, structure and chemical composition.
• It has a cuticle (a strong outer covering, as an exoskeleton), four main epidermal cords, and a fluid-filled pseudocoelom (body cavity).
• Because trilobites had wide diversity and an easily fossilized mineralised exoskeleton, they left an extensive fossil record.
• Crabs are generally covered with a thick exoskeleton, composed primarily of highly mineralized chitin.
• Most redlichiids are rather flat (or have low dorso–ventral convexity) and their exoskeleton typically has an oval outline, about 1½× longer than wide.
• Some vertebrate animals, such as the turtle, have both an endoskeleton and a protective exoskeleton.
• Hermit crabs' soft (non-calcified) abdominal exoskeleton means they must occupy shelter produced by other organisms or risk being defenseless.
• The sexes are different, the male being brownish and well-sclerotized (armoured), while the female has a relatively soft exoskeleton and is usually whitish in colour, as are the juveniles.
• Atta ants have three pairs of spines and a smooth exoskeleton on the upper surface of the thorax, while Acromyrmex ants have four pairs and a rough exoskeleton.
• Membranipora membranacea colonies consist of individual organisms called zooids, each with a chitinous exoskeleton which is secreted by the epidermis.
• When Spyke returns in the fourth-season episode "Uprising", he has permanently manifested a spiky exoskeleton across his upper body and gained the ability to ignite his spikes.
• After shedding their exoskeleton (moulting), the juvenile arthropods continue in their life cycle until they either pupate or moult again.
• A carapace is a dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises.
• Crustaceans are a large class of arthropods classified by having a hard exoskeleton made of chitin or chitin and calcium, three body regions, and jointed, paired appendages.
• Like other crustaceans, lobsters have a hard exoskeleton which they must shed in order to grow, in a process called ecdysis (molting).
• Among them is a creature in a mechanical exoskeleton, named Sathanas, who kills all but one of the scientists, whom Sathanas uses to meet Senator Aldus Hilltop.
• The impetus for firepaste came from a failed fire test with the Ursus Mark VII where the metal exoskeleton heated up, popped the air bags and left Hurtubise with numerous burns.
• The iridescence common to these beetles is not due to pigments in the exoskeleton, but instead is caused by structural coloration, in which microscopic texture in their cuticle selectively reflects specific frequencies of light in particular directions.
