Gerbils are desert burrowing animals, so I would think (I am not a biologist) that they have small ears to help reduce sand getting in their ears. They originated in Mongolia, which is between China and Russia (the old Soviet Union for those of us who are older), so it is colder there, so smaller ears would reduce heat loss as well. They are desert animals, but not all deserts are cold. :)
Gerbils primarily chew their ears as a part of their grooming behavior. They use their front paws to scratch and clean their ears, but chewing is more common to help remove dirt and maintain hygiene. This behavior is typical for many small mammals, as it helps them keep their fur and skin healthy.
A rabbit with small ears has small ears and a rabbit with big ears has big ears.
Gerbils are small, furry rodents with long tails and tufted feet, while rats are larger rodents with longer bodies and smaller ears. Gerbils are generally more social and less likely to bite than rats. Gerbils have a more herbivorous diet, while rats are omnivorous.
gerbils mostly live in pairs or small groups so it depends on the size of the cage and if the gerbils know each other
not very big because i have 2 gerbils and my cage is small
no gerbils don't have feathers, they have fur
One reason is gerbils have furry tails unlike mice having naked tails. Mice are a little smaller than gerbils. Third gerbils are much more active then mice. And finally mice normaly have much bigger ears than gerbils. I hope this helps.
not unless you get a really small stall
no the ears are small
Small ears don't get scratched by brambles.
That's just the way God made them.
Polar bears have small ears because they are special.:)Polar bears have small ears because they are special.:)
