Ears:
- Its large ears cover the whole shoulder.
- These ears can grow as large as 2 m × 1.5 m (6.6 ft × 4.9 ft).
- Large ears help to reduce body heat.
- By flapping them they create air currents.
- The ears' inner sides have large blood vessels that increase heat loss during hot weather.

- Its occipital plane slopes forward.
- Its back is shaped markedly concave.
Tusks of African bush elephant:
- The tusks erupt when elephants are 1–3 years old and grow throughout life.

Intelligence of Asian elephants :
- Several students of elephant cognition and neuroanatomy says that Asian elephants are highly intelligent and self-aware.
- Asian elephants have knowledge and cognitive abilities of tool use and tool-making similar to great apes.
Threats for Asian elephants :
- Asian elephants are poached for ivory and a variety of other products including meat and leather.
- Since 1986, the Asian elephant has been listed as Endangered on the IUCN Red List.
- { International Union for Conservation of Nature (Founded in 1964)
