The Process

Megabat
Megabats
There are over 900 different kinds of bats in the world, most are found in the tropics.
The megabats are large and found in tropical rain forests (like Australia and Africa). These bats are also called flying foxes because they look like foxes or dogs.
They either eat fruit or drink nectar from flowers, and sometimes look for food during the day instead of at night. They can see well. They have large eyes, simple ears, and simple noses. Stellaluna is a megabat.
>The biggest bat in the world is the gigantic flying fox and it is found in Asia. It weighs over 2 pounds and has a wingspan of about 6 feet. Take a look at some different types of megabats, which one do you like the most?
Microbat
Information
Microbatshttp://projects.edtech.sandi.net/chavez/batquest/images/brazilian_bat.gif
The majority of bats are microbats. Microbats (microchiropterans) are small bats found all over the world, including the U.S. There are at least 4 types of bats in California. The biggest population of bats are the red bats.
Most microbats eat insects. A red bat can eat up to 600 mosquitoes in one night. Some types of microbats eat bigger animals like rodents, other bats, reptiles, birds and even fish.
Microbats have very poor eyesight and use highly sophisticated echolocation, or radar, to find their food. That is why their ears are very large and their eyes are small.
Microbats live in different places. It is important that a bat's home is warm, the temperature needs to be between 80 and 90 degrees farenheit. That is why many bats live together in caves. Microbats also can live in trees, buildings and houses if the temperature is between 80 and 90 degrees.
