[Protected Status: ENDANGERED] The American crocodile is considered an endangered species in nearly all parts of its North, Central, and South American range. Survey data, except in the United States, is poor or nonexistent, but conservationists agree that illegal hunting and habitat depletion has reduced populations of this wide-ranging reptile to critical levels.
Number 6 on Australia's deadliest animals list - The Salt-water Crocodile - Crocodiles are highly publicised for viciousness and aggression, along with looking scary, it is probably a surprise they are further down the list than you may have thought, this is because there are very few deaths per year - The longest croc ever measured and verified was 6.4m (21ft). It could have weighed more than 1000kg. In Australia, there are unverified reports of crocs up to 8m.
