Cloven hooves of roe deer (Capreolus capreolus), with dewclaws. The hoof is the tip of the toe of an ungulate mammal, strengthened by a thick horny covering. The hoof consists of a hard or rubbery sole, and a hard wall formed by a thick nail rolled around the tip of the toe. Both the sole and the edge of the hoof wall normally bear the weight ...
Other cloven-hooved animals (such as giraffes and pronghorns) have no dewclaws. In some so-called "cloven-hooved" animals, such as camels, the "hoof" is not properly a hoof – it is not a hard or rubbery sole with a hard wall formed by a thick nail – instead it is a soft toe with little more than a nail merely having an appearance of a hoof.
Horns are projections from the top of the head. 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.
General characteristics include cloven hooves and usually at least one of the sexes of a species having true horns. The largest extant bovine is the gaur . In many countries, bovid milk and meat is used as food by humans.
Ungulates (meaning roughly "hoofed" or "hoofed animal") are several groups of mammals most of which use the tips of their toes, usually hoofed, to sustain their whole bodyweight whilst moving. The main article for this category is ungulate .
All bovids have four toes on each foot – they walk on the central two (the hooves), while the outer two (the dewclaws) are much smaller and rarely touch the ground. [ 3 ] The bovids show great variation in size: the gaur can weigh more than 1,500 kg (3,300 lb), and stand 2.2 m (87 in) high at the shoulder. [ 27 ]

Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
