Why are there so many posionious animals in Australia compared to everywhere else?

Answer 1

There are very few poisonous animals but many venomous one. There is a difference. A puffer fish is poisonous if you eat it, a stone fish is venomous if it sticks its spines in you.

Australia is detached from much of the rest of the world and its animals have had a chance to evolve in isolation. The venomous snakes have developed lethal venoms but they affect different species in different ways. Humans are one species that is killed quite easily by the venom.

Our snakes are shy and very few people are bitten, even fewer die from bites. Nealy everyone bitten by a snake was either trying to kill it or catch it. We also have some nasty spiders and an alarming collection of venomous sea creatures - but we share those with many of the other countries of the South Pacific and Indian Oceans.

While we are proud of our venomous creatures, most Australians have never seen any of them outside a zoo.

It's an environmental adaptation, like the fish at the bottom of the ocean who produce their own light.
