Why do Elephants have big ears? (hint: it goes beyond hearing)

For an elephant, their huge ears are crucial to their survival beyond only hearing.

The large size of the elephant ears allows them to regulate their body temperature, mainly to drop their body temperature during hot days.

Blood vessels in the ear are close to the surface, so when they need to cool down, they flap their ears to create airflow and release heat.

Read on to find out more reasons why the Elephants have such big ears as well as differences in ear size between the different species of Elephants.


Facts about the Elephant Ear

Here are the top 9 facts about the Elephants ears which you may find interesting:

  1. The elephant ear is made up of a thin layer of skin that is covered in hair.

  3. Elephants use their big ears to regulate their body heat, mainly because elephants have very few sweat glands.
  4. The large surface area of an elephant’s ear helps to dissipate heat and keep them cool in hot climates.
  5. To stay cool, elephants will flap their ears which creates airflow and releases heat from their body.
  6. The blood vessels in an elephant’s ear are close to the surface, so when they need to cool down, they can increase blood

  9. The African elephant’s ear has more blood vessels than the Asian elephant’s ear.

Elephants use their ears as fans

Elephants big ears not only help them to hear better, but they also use them as fans to keep cool. When it’s hot, elephants will flap their ears to create airflow and release heat from their body. The Elephant body can adjust its’ temperature by 3 to 5 degrees using their ears!

The big ears of an elephant are an important part of their anatomy, helping them to stay cool in hot climates and to pick up sounds over long distances.

There’s a distinct size difference between the Asian elephant and African elephant.

The African elephant’s ear is much larger than the Asian elephant’s ear. The African elephant’s ear also has more blood vessels than the Asian elephant’s ear.

This is likely because the African continent is generally hotter than Asia, so the African elephants need larger ears to help them stay cool in extreme temperature environments. The smaller ears of Asian elephants are more suited to the cooler climates of their geographical region.

In terms of looks, these are the main differences:

  • The African elephant’s ear is shaped like the continent of Africa (!)
  • The African elephant’s ear is darker in color than the Asian elephant’s ear.
  • The African elephant’s ear is more wrinkled than the Asian elephant’s ear.

Elephants have big ears because they need them to stay cool in hot climates and to communicate with each other over long distances. Their large ears also help them to hear better than most other animals.

The African elephants ears are larger than the Asian elephants ears, and the African elephant’s ear is darker in color than the Asian elephant’s ear. The African elephant’s ear is also more wrinkled than the Asian elephant’s ear.

Elephants use their big ears to regulate their body heat, mainly because elephants have very few sweat glands.

The large surface area of an elephant’s ear helps to dissipate heat and keep them cool in hot climates. To stay cool, elephants will flap their ears which creates airflow and releases heat from their body.

The blood vessels in an elephant’s ear are close to the surface, so when they need to cool down, they can increase blood flow to their ears which helps to dissipate heat.

Their large ears also help them to pick up sounds over long distances.
