Do you know how many kinds of plants and animals there are in the world? Scientists believe there are over 8 million, but right now we only know about 1.8 million. 1.
In 2012, a team of researchers led by a university professor named Austin discovered a new kind of animal. They were in Papua, studying the wide kinds of life of the island. One day, the researchers were listening to the sounds of frogs at night. 2. At first, they couldn’t tell where the sounds were coming from, but after some time they found they were coming from the ground. They started to look carefully among the leaves. They were expecting to find an insect(昆虫). 3. It was a
really tiny frog...just about 7 mm long! “This frog has a sound that doesn’t sound like a frog at all. It sounds like an insect,” said Austin. The frog they discovered was the smallest frog in the world.
Researchers believe that frogs and insects are very important. They help to keep our environment clean. We can also use them to make new medicine.
Researchers all over the world are working very hard to look for new plants and animals every day. 4. This is because forests where those animals live are becoming smaller.
