Answer:

Giraffes are the world's tallest mammals, thanks to their towering legs and long necks. A giraffe's legs alone are taller than many humans—about 6 feet . These long legs allow giraffes to run as fast as 35 miles an hour over short distances and cruise comfortably at 10 miles an hour over longer distances.

Giraffes grow to nearly their full height by four years of age but gain weight until they are seven or eight. Males weigh up to 1,930 kg (4,250 pounds), females up to 1,180 kg (2,600 pounds). The tail may be a meter in length and has a long black tuft on the end; there is also a short black mane. Both sexes have a pair of horns, though males possess other bony protuberances on the skull. The back slopes downward to the hindquarters, a silhouette explained mainly by large muscles that support the neck; these muscles are attached to long spines on the vertebrae of the upper back. There are only seven neck (cervical) vertebrae, but they are elongated. Thick-walled arteries in the neck have extra valves to counteract gravity when the head is up; when the giraffe lowers its head to the ground, special vessels at the base of the brain control blood pressure.

The gait of the giraffe is a pace (both legs on one side move together). In a gallop, it pushes off with the hind legs, and the front legs come down almost together, but no two hooves touch the ground at the same time. The neck flexes so that balance is maintained. Speeds of 50 km (31 miles) per hour can be maintained for several kilometers, but 60 km (37 miles) per hour can be attained over short distances. Arabs say of a good horse that it can “outpace a giraffe.”

Giraffes live in nonterritorial groups of up to 20. Home ranges are as small as 85 square km (33 square miles) in wetter areas but up to 1,500 square km (580 square miles) in dry regions. The animals are gregarious, a behavior that apparently allows for increased vigilance against predators. They have excellent eyesight, and when one giraffe stares, for example, at a lion a kilometer away, the others look in that direction too. Giraffes live up to 26 years in the wild and slightly longer in captivity.

Hope it helps you :)

  • The giraffe (Giraffa) is the tallest living terrestrial animal and the biggest ruminant in Africa.
  • Giraffa camelopardalis, a single species with nine subspecies, has long been thought to exist.
  • Based on studies into the mitochondrial and nuclear DNA as well as morphological measurements of Giraffa, the existence of up to nine living giraffe species has been identified.
  • Seven more fossil-based ancient species are now extinct.
  • The giraffe's long neck and legs, horn-like ossicones, and unusual coat patterns are its most identifying features.
  • It belongs to the Giraffidae family, which also includes the okapi, its closest living cousin.
  • Its fragmented range stretches from Chad to South Africa in the north, and from Niger to Somalia in the east.
  • Giraffes like savannahs and woods as their natural habitats. Leaves, fruits, and flowers of woody plants, particularly acacia species, serve as their primary source of nutrition.
