Giraffidae: Giraffids have a pair of skin covered bony bumps on their heads, called ossicones. Cervidae: Most deer have antlers, which are not true horns due to lacking a bone core and made of keratin. Rhinocerotidae ...
The horns can be lethal: oryxes have been known to kill lions with them, and they are thus sometimes called sabre antelopes (not to be confused with the sable antelope). The horns also make the animals a prized game trophy, which has led to the near-extinction of the two northern species.
The narwhal was scientifically described by Carl Linnaeus in his 1758 Systema Naturae. [5] The word "narwhal" comes from the Old Norse nárhval, meaning 'corpse-whale', which possibly refers to the animal's grey, mottled skin [6] [7] and its habit of remaining motionless when at the water's surface, a behaviour known as "logging" that usually happens in the summer.

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" [6] or "horn" [4]).
Pecora is an infraorder of even-toed hoofed mammals with ruminant digestion. Most members of Pecora have cranial appendages projecting from their frontal bones; only two extant genera lack them, Hydropotes and Moschus. [2] The name "Pecora" comes from the Latin word pecus, which means "cattle". [3] Although most pecorans have cranial appendages ...
