Antler comes from the Old French antoillier (see present French : "Andouiller", from ant-, meaning before, oeil, meaning eye and-ier, a suffix indicating an action or state of being) [3] [4] possibly from some form of an unattested Latin word *anteocularis, "before the eye" [5] (and applied to the word for "branch" or "horn" [4]).
Animals where this occurs include antelopes, musk-deer, camels, horses, wild boar, some apes, seals, narwhal, and walrus. [6] Male dogs have larger canines with different contour than do females. [7] Humans have the proportionately smallest male canine teeth among all anthropoids and exhibit relatively little sexual dimorphism in canine tooth size.
Musk deer can refer to any one, or all eight, of the species that make up Moschus, the only extant genus of the family Moschidae. [1] Despite being commonly called deer, they are not true deer belonging to the family Cervidae, but rather their family is closely related to Bovidae, the group that contains antelopes, bovines, sheep, and goats.
The spitting cobra has evolved to aim the venom that it spits into or as close as possible to the antagonist’s face and eyes. [1] The cobras can measure and adjust the venom dosage being delivered, based on the size and relative distance of their target, in order to ensure the highest envenomation potential possible.
Some animals – usually, but not always, prey animals – have their two eyes positioned on opposite sides of their heads to give the widest possible field of view. Examples include rabbits, buffalo, and antelopes. In such animals, the eyes often move independently to increase the field of view.
Tusks are thought to have adapted to the extra-oral environments, like dry or aquatic or arctic. [1] In most tusked species both the males and the females have tusks although the males' are larger. Most mammals with tusks have a pair of them growing out from either side of the mouth. Tusks are generally curved and have a smooth, continuous surface.
Paired, mobile, and segmented, they are located between the eyes on the forehead. Embryologically, they represent the appendages of the second head segment. [8] All insects have antennae, however they may be greatly reduced in the larval forms. Amongst the non-insect classes of the Hexapoda, both Collembola and Diplura have antenna, but Protura ...
Pit refers to special infrared-sensitive receptors located on either side of the head, between the nostrils and the eyes. In fact the pit looks like an extra pair of nostrils. All snakes have the ability to sense warmth with touch and heat receptors like other animals; however, the highly developed pit of the pit vipers is distinctive.
