I personally think that animals have big ears because they can hear carefully like if a predator is sneaking up to it's prey then they would be able to escape.
But, also, by Fennagirl:
Because Noddy wouldn't pay the ransom.
there are no animals that have ears on there sides unless they have a birth defect
listening to loud audio for a long period time can decibels your ears.
Because of the way we formed from our cousins. Which are primates which is scientifically proven.
Some animals have very large ears, such as the desert fox. Their ears have lots of blood-carrying capillaries close to the inner surface of the ear, which allows for their body temperature to be more easily regulated. Many animals escape the heat by going underground during the daylight hours, such as bobcats, hares, and/or rabbits. Others may just lie in shaded areas, like deer.
Tympanic membrane
because that's how god created them
They aren't long for any particular reason, they have adapted to being long to protect the inside of their ears

The genes of animals it originates from.
through their ears.
Some animals whose ears are bigger than human ears are horses, elephants, and some larger breeds of dogs.
Animals use their ears to hear sounds in their environment, communicate with each other, and detect potential dangers. Ears also help animals maintain balance and orient themselves. Some animals, like bats, use their ears for echolocation to navigate and find prey.
Depending on the breed of dog, the ears will be held in different positions. Boston terrier, have narrow pointy ears set far apart on their head. Malamutes have strait rounded ears. Labradors have triangluar drooping ears. Greyhounds have the rosebud/folded ears (usually). Jack Russels have button ears. It really all depends on the individual.
Some animals have unique ear adaptations that help them survive in their environments. For example, the large ears of elephants help them regulate body temperature in hot climates. Bats have large ears to help them navigate and locate prey using echolocation. The long ears of jackrabbits help them hear predators approaching in open habitats. These adaptations allow these animals to thrive in their respective environments.
animals can have holes for ears or can use smell if they don't have ears
The shape of an animal's ears can help determine how well it can hear. Large ears tend to collect and funnel more sound waves to the ear canal, improving hearing sensitivity. The distinctive shapes of some animals' ears can also help them detect the direction of a sound more accurately.
YES! i think that dolphins have 15 times the hearing we do
