The lionfish is beautifully hypnotizing, with its fiery red-orange color and intricate rays for fins. Those beautiful bright colors and the fan-like fins might tempt first-time snorkelers into reaching for one, but that would be one dumb move to make.
These exotic-looking fishies are incredibly poisonous. When they sense a threat they can use their beautiful stingers to inject lethal poison, which comes down to an excruciatingly painful experience.
Plenty of people love dogs, and for good reason. They're cuddly, they love to play, and they're great for exercise. However, you're probably aware that there are plenty of dogs out there that aren't too friendly. Fatal dog attacks end up with somewhere from thirty to fifty deaths per year, and for some reason, the number is increasing.
Whether this is wild dogs who are protecting themselves or poorly trained dogs that escape their leash, dogs aren't all cuddly, furry friends. However, it's important to remember that even the dogs with the highest number of fatalities – pit bulls – are often perfectly well-trained and like to chase sticks just like the rest of them.
What could this tiny fly do to hurt anybody? Lots – far too much, if you're talking to some people. These little flies can transmit a parasitic disease called leishmaniasis, which has a number of forms, the worst of which is quite deadly.
While most of the forms are treatable if still dangerous, visceral leishmaniasis is ninety-five percent fatal in untreated cases. Thanks to this disease, the humble sandfly ends up being responsible for more than twenty thousand deaths per year, mainly in regions such as Afghanistan and surrounding areas. A major outbreak in 2009 was just the beginning of this disease's reign of terror.
Anyone in their right mind would steer clear of sharks. Any kind of shark, not just the great white one. Similar to the great white, the tiger shark is huge and doesn't normally attack humans, but that doesn't mean it can't.
Most of the tiger shark attacks happen during the night. If you do have a tiger shark coming across your path while in the ocean, you do not need to panic, just try to keep calm (as much as you can, you are still a short distance away from an apex predator) and swim away to safety.
Poison Dart Frogs
Living in the tropical, humid regions of South and Central America, these poisonous frogs can kill 10 people with their poison. They get their poison from their diet of ants, termites, and mites. Small, but deadly, these frogs can be as small as 1.5 cm in adult length and weigh on average a slight 1 oz.
Why are they called Poison Dart frogs? Indigenous tribes used their poison to make poisonous arrows when hunting for food. While their bright colors are stunning, they are a sign of the toxicity of the species and a way to warn potential predators to stay away.
