Some simply grip the surface with the claws at the end of the legs. About 84 percent of all known species of animals are members of this phylum. Many insects hatch as grubs or caterpillars, which do not have segmented limbs or hardened cuticles, and metamorphose into adult forms by entering an inactive phase in which the larval tissues are broken down and re-used to build the adult body.

[13] Their cuticles vary in the details of their structure, but generally consist of three main layers: the epicuticle, a thin outer waxy coat that moisture-proofs the other layers and gives them some protection; the exocuticle, which consists of chitin and chemically hardened proteins; and the endocuticle, which consists of chitin and unhardened proteins.

Insects have wings as well as legs.
They develop into the adult form through a process called metamorphosis. Arachnids include spiders and mites. For example, the insect family Aphididae has mouthparts adapted for piercing vegetation and sucking out plant juices. [66] The Jurassic and Cretaceous periods provide a large number of fossil spiders, including representatives of many modern families. [17] In some segments of all known arthropods the appendages have been modified, for example to form gills, mouth-parts, antennae for collecting information,[16] or claws for grasping;[18] arthropods are "like Swiss Army knives, each equipped with a unique set of specialized tools. [29], Because arthropods are unprotected and nearly immobilized until the new cuticle has hardened, they are in danger both of being trapped in the old cuticle and of being attacked by predators.

[13], Originally it seems that each appendage-bearing segment had two separate pairs of appendages: an upper and a lower pair. Views expressed here do not necessarily reflect those of ScienceDaily, its staff, its contributors, or its partners. The word arthropod comes from the Greek ἄρθρον árthron, "joint", and πούς pous (gen. podos (ποδός)), i.e. Crustacea usually have gills that are modified appendages. Friends and foes, arthropods rule the world, Arthropods make up the most species-rich and diverse group of animals on Earth, with numerous adaptations over 500 million years of evolution that have allowed them to exploit all major ecosystems.

The new exoskeleton, when first produced, is soft and flexible, leaving the animal vulnerable to both predators and environmental changes.
