1. Piranhas: Aquatic Janitors & Veggie Lovers

While you might think piranhas are nature's equivalent of a chainsaw massacre, they're really just the unsung janitors of the aquatic world, picking up after the wild party that is the Amazon eco-system: Piranhas not only keep the South American waters tidy by devouring decaying matter as scavengers and predators but also surprise us with their leafy ambitions, as some species have a penchant for vegetarianism, munching on plants and fruits.

2. Steak Drop Food Fight

If a steak fell from a tree and into a river, who'd be the first to scream "food fight"? Why, piranhas, of course!: These razor-toothed fish are incredibly adaptable eaters, and will munch on anything from small fish, mollusks, insects, and crustaceans to birds, amphibians, and rodents - though they draw the line at seeds and fruits, keeping their taste buds primed for a mix of meaty morsels and the occasional plant-based nibble.

3. Misunderstood Human Bumpers

Who says you can't swim with the fishes without getting wet? Well, sharpen those teeth and prepare to be schooled: Piranhas are not inherently aggressive towards humans, and most encounters result in nothing more than a few bumps and bruises. They'd rather nibble on plants, seeds, and other fishy tidbits, only turning to humans in times of food scarcity or during their breeding season – and even then, serious injuries remain rare.

4. Piranha: The Waterproof Watch

Who needs a waterproof watch when you've got a piranha by your side? These fishy fellows can tolerate low oxygen levels and even some terrestrial shenanigans, so long as they're kept moist with a splash of water or a damp towel: Despite their terrifying Hollywood reputation, piranhas are actually quite the multidisciplinary gourmands, feasting on insects, mollusks, and crustaceans, with only a select few indulging in fish or taking on a scavenger role with larger carcasses.

5. Shy Nemos with a Sharp Bite

While piranhas may have a reputation as the schoolyard bullies of the aquatic world, it turns out they're less Jaws and more Nemo: Contrary to popular belief, piranhas are far from bloodthirsty killers, with attacks on humans proving extremely rare, as they are more shy and non-aggressive creatures, only demonstrating a sharper bite when hunting or defending their young.

6. Piranha's Teeth Top Hats

You might say that piranhas have a real flair for interior "molar" decorating – they prefer to dress their new teeth in fancy, "elder-teeth" top hats: Piranhas and pacus continuously lose and regrow all the teeth on one side of their face, with new teeth sporting the old ones as fashionable "hats" until they're ready to emerge, ensuring that these fishy fashionistas never go toothless.

8. Romantic, Doting Piranha Parents

Who says bloodthirsty can't be lovey-dovey too? Piranhas, nature's dentists with a wild side, are actually suckers for romance when spawning season comes-a-knockin': These ferocious fish morph into doting parents, building a cozy nest for their eggs, guarding them as they hatch, and keeping a watchful eye on their little munchkin-piranhas as they venture into the world.

12. Black Piranhas: Weightlifting Champs

What do piranhas and weightlifting champions have in common? They both pack a serious bite – but only one prefers their steak with a little extra splash: The black piranha's bite force is equivalent to 30 times its bodyweight, making it the strongest biter in comparison to its size in the natural world – outmatching even the bite force of legendary predators like Tyrannosaurus rex and megalodon.
