Poison Dart Frog
The sprightly and brightly colored frog may look enchanting, but it can produce enough poison to kill 10 humans. Thriving in humid, tropical environments of Central and Latin America, the poison dart frog oozes black slime from its back, which is actually a neurotoxin used to ward off predators.
Australian Box Jellyfish
Found across the northern half of Australia – particularly in Queensland – the box jellyfish washes up on the shores after heavy rain and high tide. If stung, the venom contained in their tentacles attacks a human’s cardiac and nervous system – even when the tentacles aren’t attached to the jellyfish’s body. Immediate treatment is necessary to prevent death.
While extremely irritating, mosquitoes are also extremely dangerous. Mosquito-borne diseases include yellow fever, dengue fever and malaria, which account for the death of two million people every year.
The deathstalker scorpion is the deadliest of all scorpions, accounting for 75 percent of scorpion-related deaths. Filled with neurotoxins, the poison is most likely to kill children and the elderly. Accordingly, scorpion poisoning accounts for more than five thousand deaths every year.
Dwelling deep in the oceans of Australia, New Guinea, Indonesia and the Philippines, the blue-ringed octopus is the size of a golf ball. But don’t let its size fool you: the venom in the octopus can cause motor paralysis and lead to cardiac arrest. Worse still, there is no known antidote to its poison.
Another Aussie killer, the stone fish dwells in the Great Barrier Reef as well as the Tropic of Capricorn. Camouflaged as a rock, the fish has enough sting to cause shock, paralysis and tissue death. Its venom is located in the 13-spined dorsal area and the pain from the sting is sometimes so severe that amputation may be necessary.
