The giraffe (Giraffa camelopardalis, ssp. tippelskirchi shown here) is the tallest living terrestrial animal and the largest ruminant. There are nine subspecies, which are distinguished by their coat patterns. Fully grown giraffes stand 5–6 m (16–20 ft) tall, with males taller than and weighing nearly twice as much as females. The giraffe's scattered range extends from Chad in the north to South Africa in the south, and from Niger in the west to Somalia in the east. Giraffes usually inhabit savannas, grasslands, and open woodlands. Their primary food source is acacia leaves, which they can browse at heights which most other herbivores cannot reach.
