Why are there the most unknown living creatures in tropical forests?

In tropical forests, the most comfortable conditions for the existence of most species. There the optimum temperature (not too hot, not too cold), humidity, etc. The rainforests are home to many unique plants that provide food and shelter for animals. Such conditions can lead to intense speciation.

Many new species have been discovered in these forests, some of which are unique to this climate, but most have yet to be discovered. Many of them are microscopic, making them difficult to detect. Also, there may be twin species that are mistaken for already open ones.

Most of the species unknown to science belong to insects or roundworms, because they are the most numerous of the animals. For insects, conditions in tropical forests are more than favorable, and according to scientists, each type of animal or plant has its own kind of roundworm.
