Horned gophers are extinct rodents from the genus Ceratogaulus, a member of the extinct fossorial rodent clade Mylagaulidae. Ceratogaulus is the only known rodent genus with horns, and is the smallest known horned mammal.
The royal antelope (Neotragus pygmaeus) is a West African antelope recognized as the world's smallest. It was first described by Swedish zoologist Carl Linnaeus in 1758. It stands up to merely 25 cm (10 in) at the shoulder and weighs 2.5–3 kg (5.5–6.6 lb).
True horns are found mainly among: Ruminant artiodactyls. Antilocapridae ; Bovidae (cattle, goats, antelopes etc.). 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.
The weight is reported to range from 500–1,000 kg (1,100–2,200 lb), averaging 700–800 kg (1,540–1,760 lb). Like both African species, it has two horns; the larger is the nasal horn, typically 15–25 cm (5.9–9.8 in), while the other horn is typically a stub. A coat of reddish-brown hair covers most of the Sumatran rhino's body.
A pair of horns on a male impala Anatomy of an animal's horn. A horn is a permanent pointed projection on the head of various animals that consists of a covering of keratin and other proteins surrounding a core of live bone. Horns are distinct from antlers, which are not permanent.
One pair of horns is located between the ears, and the other on the forehead. The posterior horns are always longer than the anterior horns, which might be mere fur-covered studs. While the posterior horns each measures 8–12 centimetres (3.1–4.7 in), the anterior ones measure 2–5 centimetres (0.79–1.97 in).
A dik-dik is the name for any of four species of small antelope in the genus Madoqua that live in the bushlands of eastern and southern Africa. [1]Dik-diks stand about 30–40 centimetres (12–15.5 in) at the shoulder, are 50–70 cm (19.5–27.5 in) long, weigh 3–6 kilograms (6.6–13.2 lb) and can live for up to 10 years.
Since the fur can only be removed from dead animals, and each animal yields very little of the downy fur, several antelope must be killed to make a single shawl. This unsustainable demand has led to enormous declines in the chiru population. [17] [18] The saiga is hunted for its horns, which are considered an aphrodisiac by some cultures. Only ...
