Usually more of an irritation than a source of death, flea bites can sometimes become infected, in which case they can be deadly. You mostly need to worry about the diseases they carry with them. As external parasites of mammals and birds, they live by consuming the blood of their hosts using mouthparts fitted for penetrating the skin and sucking blood.
They don’t have wings, but they have hind legs adapted for jumping, which allow them to jump a crazy distance 50 times their body length. They are one of the best-known jumpers out of the entire animal kingdom, relative to their body size.
Death Stalker
Do you know how sometimes scientists go with a Latin name for a new species they discover? Well, when faced with this deadly critter and its hellish stinger, they went with something a lot simpler. With a creepy name like that, you can't ignore the fact that this venomous scorpion is super dangerous.
Causing horrible pain in adults, and fever, coma, convulsions, and paralysis in children, this scorpion is found in areas of North Africa and the Middle East, and it is responsible for 75% of scorpion-related deaths every year.
Black Spitting Thick Tail Scorpion
This nocturnal scorpion poisons its victims by stinging or spraying them. They are characterized by their super thick tail. The name is a dead giveaway (pun intended), so you could probably guess it yourself.
They are found in dry parts of southern Africa and are also known as the thick-tailed scorpion, dark scorpion, or giant deathstalker (all fantastic names that sound just as cuddly as they should). Be careful because they are easily frightened and cause many deaths every year.
Cone Snail
Also known as the “cigarette snail,” this little thing can kill 20 people with one drop of its venom. A sting by this animal leaves you just enough time to smoke one cigarette before dying. They are usually found in warm and tropical seas and oceans.
People are often attracted to their color and may want to pick them up. However, their sting will occur at random and is capable of penetrating the skin, gloves, or wetsuits. Plus, there is no antivenom, so it is best that you avoid this lethal critter.
Deer Ticks
Just like many other tick species, this tick is known to spread diseases. With these guys, you need to worry about Lyme disease. They are mostly found in forests in North America, so watch out for them.
Fortunately, their preferred host is, of course, deer, which is just one reason why you should just pet random deer. You are not a Disney princess. They are also known to feed on small rodents, so don't go around petting those either.
