Brazil and Australia. However, Australia is known to have the most dangereous species of animals and insects in the whole world. e.g -8/10 of the worlds most deadliest snakes live in Australia -Australia is the only country where its venomous snakes out-number non-venmous snakes. -Stonefish (otherwise known as the Rockfish). where a single drop of venom can kill up to 3 adults. -The top marine preditors 1) Bull Shark 2)Tiger Shark 3) Great White (otherwise known as the White Pointer or Noah) -Box Jellyfish (most venomous jellyfish in the world) -Closely followed by the Irukandji jellyfish that occupies Northern areas of Australia such as Queensland. This jellyfish is one of the worlds smallest jellyfish, 1/4 of the size of your pinky nail, but contains a lethal venom. -Blue Ring Octopus. Though no bigger that your palm, a sting can result in death in mere minutes without proper treatment. -The Funnel Web Spider, (worlds deadliest spider) no bigger than a 20c piece, it carries a lethal venom with fangs measuring up to just under a cm. The list just goes on and on. So if you go camping in Australia, make sure you prepared! Hope this helps.

Its India, and not Brazil or Australia. The fact that non-venoms out number Venoms in Australia just shows the fact that there are only a few which survive there. In India you have the leapords that you find in Brazil to Tigers, and Lions that are found in Africa to King Cobras to Gharials that are found no-where else. There is not a genus that is not found in India in one form or the other. Sadly they are not doing well in India and like the Cheetah, which last roamed in India some 150+ years they will be no more.

Its the Philippines. According to United Nations Redbook this country has a high endemicity rate and it has a lot of species there.

No doubt, it's India! In India there are more number of species than any other part of the world. Ironically the Indian Government doesn't takes any action to preserve these Jewels.

idk how the conversation got converted to venomous animals but I do believe it's Brazil, that is if you're counting insects. The rainforest of Brazil and surrounding areas.
