You will learn the usage of collecting nets.
After completing this tutorial, you will be able to complete the following:
Field biologists use a variety of tools, including nets, to collect animals for their research. The net that is used depends on the kind of animal that the researcher wants to collect, and where the animal lives. There are three main types of collecting nets. Nets designed especially for collecting flying insects, such as butterflies and moths, are called aerial nets. Both the bag and handle of an aerial net are relatively lightweight. Their light weight makes them easy to use, and also helps to avoid harming the insects. Nets used for sweeping through dense vegetation are similar to aerial nets, but are more durable, with a stronger bag. These nets, called sweeping nets, are used to collect insects that live in trees and shrubs. A third type of net is used for collecting animals that live in the water. These more durable nets, called aquatic nets, are usually made of metal screening or heavy woven fabric.
