Are there any animals that have small ears?
But I can’t think of many cold-weather animals with especially large ears, and even those that do have smaller ears than their desert counterparts. Compare the jackrabbit to this snowshoe hare (source: Snowshoe hare ): Arctic fox. It has incredibly small ears to mininise the rate of heat loss in the permafrost of arctic.
Is it adaptive for animals to have small external ears?
On the other hand, if you’re a cold-weather animal, it’s not adaptive to radiate heat; an animal that retains its body heat and cools slowly has better odds of surviving and reproducing. In that case, small external ears are adaptive.
Why are the ears of different animals different?
Animals have different ear shapes because the ears of each animal group are adapted for their specific environment and needs. For example, predators have ears that face forward to allow them to focus on their prey. Prey animals often have ears that can be moved around.
Why does an elephant have a large ear?
Elephants, fennec foxes and many desert animals have large ears to help them stay cool. Blood travels through the animals’ ears and releases heat into the air. Bats use hearing to find their way around and catch prey by bouncing sound waves off objects in their environment.

Which is the animal with the longest ears?
The long-eared jerboa (rhymes with Samoa) measures about 4 inches (10 centimeters) from head to rump (not counting its long tail). Its ears, measuring 1.5 to 2 inches (3.8 to 5 cm) long, are 40% to 50% the length of its body. “It has the longest ears relative to its body size in the entire animal kingdom,” Holden told Live Science.
