A signature feature of elephants is their trunks. Trunks are a proboscis (nose) that are long, mobile, and muscular. Their trunks are fused with the upper lip and used for eating, drinking, tools, defense, lifting, and making vocalizations.
Elephants are grayish in color with thick and slightly wrinkled skin. They have very little hair that is coarse and brown to black in color. Their ears are large and by flapping them, are used to lower the elephant's body heat.
There are two recognized species of African Elephant. The African bush elephant is the largest of the two species. Bulls can weigh 10,362–13,334 lbs (4,700–6,048 kg) and are 10–13ft (3.2–4 m) tall. Cows weigh 4,762–7,125 lbs (2,160–3,232 kg) and are 7.2–8.5ft (2.2–2.6 m) tall.
African forest elephant is the smaller of the two species and weigh up to 8,800 lb (4,000 kg). Cows are 5 ft11 in – 7 ft 10 in (1.8–2.4 m ) at shoulder height. Bulls are 2.4–3 m (7 ft 10in – 9 ft 10 in).
All African elephants, male and female, have tusks, which are elongated incisor teeth. Tusks are made out of ivory. The tusks of a Bush Elephant are outward facing, while those of a Forest Elephant are downward facing. In addition to tusks, elephants have 24 teeth. Elephants have six sets of teeth over the course of their lives, with the last set being used when elephants are in their 50's.
