Insects
Insects are invertebrates and are the most biodiverse life form on the planet. Insects have achieved the most success compared to other branches of life, being superbly adapted to their environment. Being located in a tropical zone Thailand is a biodiversity hotspot. At least 105,000 species of insects have been discovered, of which only 10% or 10,000 have been named and characterized. Therefore, Thailand still has many insect species which are undiscovered or as yet unnamed. This is also true of Khao Yai National Park, which still has many uncharacterized species as of present.
