(hint: it goes beyond hearing)"},"content":{"rendered":"

For an elephant, their huge ears are crucial to their survival beyond only hearing.<\/strong><\/p>\n\n\n\n

The large size of the elephant ears allows them to regulate their body temperature, mainly to drop their body temperature during hot days. <\/p>\n\n\n\n

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.<\/p>\n\n\n\n

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<\/a>.<\/p>\n\n\n\n\n\n\n\n\n\n

Facts about the Elephant Ear<\/h2>\n\n\n\n

Here are the top 9 facts about the Elephants ears<\/strong> which you may find interesting:<\/p>\n\n\n\n

  1. The elephant ear is made up of a thin layer of skin that is covered in hair.<\/li>\n\n\n\n
  2. The average ear size of an adult elephant is about 0.6m (2ft) in length and 0.5m (1.6ft) in width.<\/li>\n\n\n\n
  3. Elephants use their big ears to regulate their body heat, mainly because elephants have very few sweat glands.<\/li>\n\n\n\n
  4. The large surface area of an elephant’s ear helps to dissipate heat and keep them cool in hot climates.<\/li>\n\n\n\n
  5. To stay cool, elephants will flap their ears<\/a> which creates airflow and releases heat from their body.<\/li>\n\n\n\n
  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<\/li>\n\n\n\n
  7. Their large ears also help them to pick up sounds over long distances.<\/li>\n\n\n\n
  8. The African elephant’s ear is larger than the Asian elephant’s ear.<\/li>\n\n\n\n
  9. The African elephant’s ear has more blood vessels than the Asian elephant’s ear.<\/li>\n<\/ol>\n\n\n\n

    Elephants use their ears as fans<\/h2>\n\n\n\n

    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!<\/p>\n\n\n\n

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

    Elephants also use their ears to signal their presence and to communicate<\/h2>\n\n\n\n

    Elephants also use their ears to communicate. They make a variety of sounds by flapping, folding, and wiggling their ears that can convey everything from aggression to subtle emotional states. <\/p>\n\n\n\n

    The size and shape of an elephant’s ears are unique to each individual, much like human fingerprints, which helps other elephants identify one another.<\/p>\n\n\n\n

    \n\n\n\n

    Elephants have excellent hearing<\/h2>\n\n\n\n

    Elephants have excellent hearing and can pick up low-frequency sounds that are below the range of human hearing. <\/p>\n\n\n\n

    They use their hearing to communicate with each other over long distances. Being able to hear long distances also has it perks when listening for threats.<\/p>\n\n\n\n

    \n\n\n\n

    Different elephant species have different sized ears<\/h2>\n\n\n\n

    There’s a distinct size difference between the Asian elephant and African elephant. <\/p>\n\n\n\n

    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. <\/p>\n\n\n\n

    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.<\/p>\n\n\n\n

    In terms of looks, these are the main differences:<\/p>\n\n\n\n
