Giraffe Biology and Conservation

Giraffes are iconic African animals known for their height and long necks. Adult giraffes can reach up to 18 feet, allowing them to feed on treetops. Their strong hearts and high blood pressure help circulate blood to their brains. Despite having the same number of neck bones as humans, giraffes' necks are much longer. They sleep minimally, often standing, to avoid predators. Giraffe populations are vulnerable due to hunting for their coats, meat, and tails. Their unique characteristics make them stand out among animals.
