  2. Arthropod exoskeleton - Wikipedia

    en.wikipedia.org/wiki/Arthropod_exoskeleton

    The chemical and physical nature of the arthropod exoskeleton limits its ability to stretch or change shape as the animal grows. In some special cases, such as the abdomens of termite queens and honeypot ants means that continuous growth of arthropods is not possible.

    Discarded exoskeleton of dragonfly nymph Exoskeleton of cicada attached to a Tridax procumbens (colloquially known as the tridax daisy)An exoskeleton (from Greek έξω éxō "outer" [1] and σκελετός skeletós "skeleton" [2] [3]) is a skeleton that is on the exterior of an animal in the form of hardened integument, which both supports the body's shape and protects the internal organs ...

    en.wikipedia.org/wiki/Insect_morphology

    The insect's outer skeleton, the cuticle, consists of two layers; the epicuticle, which is a thin, waxy, water-resistant outer layer that lacks chitin, and the layer under it is called the procuticle. This is chitinous and much thicker than the epicuticle and has two layers, the outer is the exocuticle while the inner is the endocuticle.

    The name army ant (or legionary ant or marabunta [1]) is applied to over 200 ant species in different lineages. Because of their aggressive predatory foraging groups, known as "raids", a huge number of ants forage simultaneously over a limited area.

    en.wikipedia.org/wiki/Skeleton

    A skeleton is the structural frame that supports the body of most animals.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.

  8. Ant - Wikipedia

    en.wikipedia.org/wiki/Ant

    An ant's head contains many sensory organs. Like most insects, ants have compound eyes made from numerous tiny lenses attached together. Ant eyes are good for acute movement detection, but do not offer a high resolution image. They also have three small ocelli (simple eyes) on the top of the head that detect light levels and polarization. [43]

  9. Metapleural gland - Wikipedia

    en.wikipedia.org/wiki/Metapleural_gland

    From the bulla, ants can groom the secretion onto the surface of their exoskeleton. This helps to prevent the growth of bacteria and fungal spores [3] on the ants and inside their nest. [4] [5] Though considered an important component in an ant's immunity against parasites, some
