- Elephant ears have thick bases with thin tips and contain numerous blood vessels called capillaries
- Elephant eyes lack a lacrimal apparatus and the field of vision is compromised by the location and limited mobility of the eyes
- Several species of proboscideans lived on islands and experienced insular dwarfism
- Dwarf elephants are known to have lived in Indonesia, the Channel Islands of California, and several islands of the Mediterranean.
- Elephant tusks are continuously growing teeth made of ivory and serve multiple purposes.
- African elephants have tusks in both sexes while Asian males have large tusks and females have small ones or none at all.

- Elephants are capable swimmers and have been recorded swimming for up to six hours without touching the bottom.
- Hunting for elephant ivory has led to natural selection for shorter tusks and tusklessness.
- Elephants are homeotherms and maintain an average body temperature of 36°C.
- They do not have sweat glands but can cool down through water diffusion and other behaviors.
- Elephants are herbivorous and consume up to 150kg of food and 40L of water per day.
- They have a huge impact on their environment and are considered keystone species.
- Female elephants live in tight-knit matrilineal family groups led by the matriarch.
