Armour, although all used for the sole intent to ward off attackers, can be split into defensive and offensive armour. Examples of offensive armour are horns, hooves, antlers, claws and beaks, clubs and pincers, as developed in some mammals, birds, reptiles (including dinosaurs, such as the dromaeosaurid claw and the ceratopsian horn) and arthropods.
Bioinspired armor are materials that were inspired by the composition, and most importantly, the microstructures commonly found in nature’s natural defense mechanisms. . These microstructures have been evolved by organisms to protect themselves from exterior forces, such as predatory atta
The word armadillo means ' little armored one ' in Spanish; [2] [3] it is derived from armadura ' armor ', with the diminutive suffix -illo attached. While the phrase little armored one would translate to armadito normally, the suffix -illo can be used in place of -ito when the diminutive is used in an approximative tense. [4]
The genus Tolypeutes contains the two species of three-banded armadillos.They are restricted to open and semi-open habitats in South America.. Of the several armadillo genera, only Tolypeutes rely heavily on their armor for protection.
Further, other lineages have produced tough outer coatings, such as some mammals, that are analogous to an exoskeleton. This coating is constructed from bone in the armadillo, and hair in the pangolin. The armour of reptiles like turtles and dinosaurs like Ankylosaurs is constructed of bone; crocodiles have bony scutes and horny scales.
Dermal scutes are also found in the feet of birds and tails of some mammals, and are believed to be the primitive form of dermal armour in reptiles. The term is also used to describe the heavy armour of the armadillo and the extinct Glyptodon , and is occasionally used as an alternative to scales in describing snakes or certain fishes, such as ...
Many animals are protected against predators with armour in the form of hard shells (such as most molluscs and turtles), leathery or scaly skin (as in reptiles), or tough chitinous exoskeletons (as in arthropods). [25] A spine is a sharp, needle-like structure used to inflict pain on predators.
The hairy long-nosed armadillo is poorly known. Like other species of Dasypus, it has a hard armour-like shell, called a carapace. The armour consists of ossified dermal plates composed of a number of movable bands covered by leathery skin. The rostrum is long and slender and is more than half the length of the head. There are long, hairless ...
