Source: Iconosquare
There are two species of tiger snake in Australia and come in yellow, orange and black. Some are totally black, and all of them are aggressive. They are very adaptable and can live in dry rocky areas, woodlands, and swamps. Their venom is made up of a cocktail of neurotoxins and anticoagulants which shuts down their victim’s vital functions while destroying blood cells causing uncontrollable bleeding.
