its an adaptation it depends what biome & or ecosystem they live in. :)
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.
Rabbits are prey animals, meaning they are hunted by other animals. Therefore, they need large ears because they rely on their sense of hearing to detect predators. They also have great speed and agility to escape predators.
animals can have holes for ears or can use smell if they don't have ears
animals such as dogs/ canines also lose heat via panting (with their tongue sticking out) or some animals lose heat through large ears ( such as elephants, also by wafting their ears to cool their bodies)
Animals with big ears include elephants, fennec foxes, and African elephants. These animals have evolved large ears to help regulate body temperature and enhance their hearing abilities, crucial for survival in their habitats.
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.
Large ears help cool animals by increasing the surface area through which heat can be dissipated. The blood vessels in the ears can release heat when exposed to cooler air, effectively lowering the animal's body temperature. This adaptation is particularly beneficial in hot environments, as it allows the animal to regulate its internal temperature more efficiently. Species like elephants and rabbits use their large ears for thermoregulation, helping them survive in extreme heat.

there are no animals that have ears on there sides unless they have a birth defect
Some dessert animals have big ears to help regulate their body temperature in hot climates. The large surface area of their ears helps to dissipate heat and keep them cool. Additionally, the blood vessels in their ears can help release excess body heat.
Polar bears, like most animals that live in cold regions, have small ears so they don't dissipate heat through them rapidly.
They are adaptations to aid the animal in it's everyday life. African elephant ears are no more efficiant for hearing than Indian elephant's ears but they are much larger in external area. This is so that large blood vessels can circulate great quantities of blood through the ear flaps quickly to aid in cooling the blood and therefore the body. Aquatic animals, water-dogs, beaver etc have different ears best adapted for their environment. Other animals have ears that rotate to give them 360 degree hearing.
