There are more than 1,200 species of bats worldwide, comprising a fifth of all the mammal species in the world. Bats are grouped with primates in the superorder Archonta.
The smallest bat, the bumblebee bat, weighs less than a penny, while the flying fox bat can weigh up to 2.4 pounds and can have a wing span of 5 to 6 feet. The diet of bats can range from insects, fruits or nectar to frogs, rodents and fish. Bats have been around since the age of the dinosaur. Bats are extremely adaptable and can live almost anywhere, except polar caps and deserts. Bats also play an important part to the ecosystem and agriculture by eating destructive insects, pollinating important flowers and fruits, and transporting seeds.
