The external skeleton of arthropods is a highly efficient system for small animals. The exoskeleton provides a large surface area for the attachment of muscles and, in addition to functioning in support and movement, also provides protection from the external environment.

What are the benefits of an exoskeleton?
Having a hard covering on the outside in the form of an exoskeleton is a great defense against predators; it helps to support the body and it's like wearing a portable raincoat that keeps the creature from getting wet or drying out. It also protects the animal's soft, inner organs and muscles from injury.
What are 3 functions of an arthropod exoskeleton?
The Exoskeleton. An insect's exoskeleton (integument) serves not only as a protective covering over the body, but also as a surface for muscle attachment, a water-tight barrier against desiccation, and a sensory interface with the environment.
What is the exoskeleton in arthropods?
Arthropods are covered with a tough, resilient integument or exoskeleton of chitin. Generally the exoskeleton will have thickened areas in which the chitin is reinforced or stiffened by materials such as minerals or hardened proteins. This happens in parts of the body where there is a need for rigidity or elasticity.
What are the advantages of arthropods?
But arthropods are also responsible for a suite of activities that are beneficial to humans: pollinating crops, producing honey, eating or parasitizing insect pests, decomposing waste, and being food for a variety of birds, fish, and mammals. Farmland abounds with beneficial arthropods.
Why the arthropod exoskeleton is often cited as the major reason for arthropod success?
EXOSKELETON MADE OF CHITIN: ... The chitinous exoskeleton is frequently cited as the major reason for arthropod success because it provides (1) structural support, (2) an impermeable surface for prevention of water loss, and (3) a system of levers for muscle attachment for movement/locomotion.
What is the exoskeleton of arthropods made from and what is its purpose?
In arthropods, the nonliving exoskeleton is like a form-fitting suit of armor. It is produced by the “skin” and then hardens into a protective outer-covering. This exoskeleton is handy in some ways (it provides protection and prevents water loss), but is limiting in others.
Do arthropods have exoskeletons?
All arthropods have a hard exoskeleton made of chiton, a type of protein. ... Although arthropods grow, their exoskeletons do not grow with them. So they must periodically shed, or "molt" their exoskeletons in favor of a new one. Arthropods ("arthro" meaning joint, and "pod" meaning leg) also have jointed appendages.
What is the function of exoskeleton in animals?
Exoskeletons contain rigid and resistant components that fulfill a set of functional roles in many animals including protection, excretion, sensing, support, feeding and acting as a barrier against desiccation in terrestrial organisms.
Why do some animals have exoskeletons?
The exoskeleton provides them with strength and support, as well as protecting the organs inside their bodies. To grow, animals with exoskeletons need to shed their old skeleton and grow a new one.
What are the advantages and disadvantages of the arthropod exoskeleton?
This is a disadvantage to the whole system, since arthropods have very little protection after they shed their old shell, until the new one hardens completely. However, there are advantages, such as the many layers that provide protection from predators and dehydration, and which completely protect organs and muscles.
What are the economic importance of arthropods?
Arthropods contribute to human food supply, pollinate crops, help maintain ecosystem sustainability by biologically suppressing destructive arthropods, but cause and transmit diseases to humans and livestock and incur crop losses.
What is unique about arthropods?
The distinguishing feature of arthropods is the presence of a jointed skeletal covering composed of chitin (a complex sugar) bound to protein. This nonliving exoskeleton is secreted by the underlying epidermis (which corresponds to the skin of other animals).
What is the advantage of Ecdysis molting in arthropods such as crustaceans?
What is the advantage of ecdysis (molting) in arthropods such as crustaceans? Molting is initiated hormonally when inhibiting hormones are decreased and molting hormones are increased. During the pre-molt phase, the old cuticle thins and separates from the epidermis.
Do arachnids have exoskeletons?
Like all arthropods, arachnids have segmented bodies, tough exoskeletons, and jointed appendages.
Do exoskeletons have backbones?
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.
