We can see here that the statement is false. While these animals mentioned—toucans, spider monkeys, tree snails, sloths, and poison-arrow frogs—are indeed inhabitants of rainforests, they do not constitute more than half of the world's animal population within rainforest environments.
Rainforests are incredibly diverse ecosystems that host an immense variety of flora and fauna. The statement exaggerates the significance of these specific animals by suggesting they make up over 50% of all rainforest-dwelling creatures, which is not accurate.
The complete question is:
Some types of fauna, such as the toucan, the spider monkey, the tree snail, the sloth, and the poison-arrow frog, comprise more than half of the world's animals that live in the rainforest. True or False.
