What is the tallest mammal in the world?

The tallest mammal in the world is the giraffe (scientific name: Giraffa camelopardalis), which is native to Africa. Giraffes are known for their long necks and legs, which allow them to browse for food high up in the trees. Adult giraffes can stand up to 18 feet tall (5.5 meters) and weigh up to 3,500 pounds (1,600 kg).

Giraffes have several adaptations that allow them to thrive in their unique environment. Their long necks contain only seven vertebrae, just like humans, but each vertebrae can be up to 10 inches long (25 cm). They also have a specialized cardiovascular system that allows them to pump blood up to their heads without fainting.

Giraffes are social animals and live in herds. They communicate with each other through a variety of vocalizations, including grunts, moans, and hisses. They also use their long necks to engage in a behavior called 'necking,' which is a way to establish dominance among males during the mating season.
