Piranha (Razor Sharp Teeths)

While the threat this little teeth-with-gills poses to humans has been rather blown up in films – including its own self-titled horror B movie – the Piranha has a set of jaws to make any dentist nod with nervous approval. Its rows of razor-sharp gnashers are tightly packed and interlock with each other, teeth perfectly designed for the rapid piercing and shearing of meat – for which the Piranha has a rapacious appetite, as if you needed to know. The Piranha is also aggressive to its own kind and can become cannibalistic if underfed. Although the Piranha hunts in a lethal, highly organised fashion, in its defence it also eats vegetable matter such as seeds. Research also suggests its habit of forming into large groups is as much a defence against predators like caimans and river dolphins as it is a killing strategy. But despite its overblown menace – with the piranha more likely to end up as part of your dinner than vice versa – you wouldn’t want to spend too long in Amazonian waters with an open cut to whet this fish’s appetite. Feeding frenzies against larger animals do happen, and this fiend will bite and maim without a second invitation. Sounds Crazy!
