Apart from the odd adder or stinging insect, in Britain we aren't troubled much by animals with poison in their attack. In other parts of the world people are less fortunate: from South America to India venomous animals abound.
Australia has more than its fair share: lurking in Sydney back gardens are funnelweb spiders, tiny, but capable of giving a lethal bite; and the seas around Australia are filled with beautiful creatures with deadly habits.
