Nature and all her creatures, both great and small, are a constant marvel to scientists and everyone else. Nobody would argue with the claws of an Alaskan brown bear, or the thundering of a charging hippopotamus. But not all of natures creatures immediately strike you as aggressive or scary.

Some of them are downright cute and cuddly.

The river otter is playful and cute to boot, but when they feel threatened they don't hesitate to attack humans. Packed with muscle and weighing up to 30 pounds, you wouldn't want to be on the wrong end of their razor sharp claws and teeth.

The puffer fish with their big eyes and dopey looking expressions, you would think of them as cute and cuddly. But one prick from the spines of the fish can kill a man. They have a highly potent neurotoxin, known as tetrodoxin. These toxins deaden the tongue and lips, and induces dizziness and vomiting, followed by numbness and prickling over the body, decreased blood pressure and muscle paralysis.

So cute, yet so deadly.

Here are ten more of natures tiniest, but deadliest creatures.

10 Golden Poison Frog

Decked in brilliant red, yellow, blue and inky black, these tiny frogs are trippy to look at. They are quite tiny too, with adults reaching the size of a human thumb. But this is an example of the brighter the colors, the farther away you should stay from the creature.

This frog is native to tropical forests, from Brazil to Peru and has helped tribes here fight their enemies for centuries. Its skin secretions contain enough neurotoxin to kill two bull elephants or ten humans. By tipping their arrows in its skin secretions, the natives developed deadly weapons to kill their enemies with.

9 Irukandji jellyfish

Found in beaches from northern Australia to Florida, watching the box jellyfish is as dreamy as what you thought it would be.

Otherworldly. Ethereal. Dreamy. Deadly.

These creatures are extremely dangerous as their tentacles are loaded with toxin. The toxin is said to be 100 times more potent than a cobra and up to 1, 000 times worse than a tarantula. Impressive for a creature only about one cubic cm in size.

These tiny jellyfish have been known to fire their stingers at their victim. Due to their tiny size, their sting may not be felt immediately when they attack. But within 30 minutes, victims start to complain of severe headaches, nausea, abdominal pain, sweating. Without immediate treatment, victims experience tachycardia, increased blood pressure and go into cardiac arrest.

Leiurus quinquestriatus is a species of scorpion native to North Africa all the way to the Middle East. Displaying bright green and golden yellow coloration, they grow to about 80mm long; some even keep them as exotic pets.

Don't be fooled by the 50 blue shimmering rings that cover the yellow skin of this ocean dwellers dorsal and lateral surfaces. Dwelling in the shallow waters and coral reefs of the eastern Indo-Pacific Oceans, parts of Japan and South Australia, you are advised to swim the other way when you encounter this octopus.

Their brilliant colors and small size mean people tend to brush against them and even pick them up sometimes. But when agitated, they bite and release a neurotoxin, that is considered 1,200 times more toxic than cyanide.

6 Spiders

Did you know that some spiders eat birds and snakes? Trust me, you want to keep away from the Golden orb-weaver spider which grows up to 5 cm (not including the leg span).

But this list is about much smaller specimens such as the redback spider. Male redback spiders are about 4mm long, and females can grow up to 10mm. Native to Australia, the redback has found its way to New Zealand, Belgium, and Japan hiding in grape exports.

5 TseTse Fly

With their bulbous, prickly eyes, houseflies are some of the ugliest flies ever. But even they pale in comparison to the threat that is the tsetse fly. Armed with a long proboscis that it uses like a syringe, it spreads the disease across species through biological transmission and mechanical transmission.

This 10mm long insect has been around since prehistoric times and is the primary vector for sleeping sickness. The parasites it transmits cause confusion, severe lethargy, fever and anemia in humans and animals. Left untreated, this disease often proves fatal.

4 Fleas

If you have pets, you may have experienced having to deal with these at one point, but fleas are more destructive than making your corgi scratch. Historically, they were the primary vectors responsible for the spread of the bubonic plague. By feeding on the blood of infected rats and biting humans, they helped rapidly spread of the disease.

3 Pfeffer’s flamboyant cuttlefish

via:en.wikipedia.org

A cephalopod like the blue ringed octopus, Metasepia pfefferi is found in Australia, off the coasts of the Philippines, New Guinea, Indonesia and Malaysia. Despite its tiny (2 to 3 inch) frame, this fish is a bold predator who attracts its prey (other fish) with its ability to rapidly change color. They have absolute control over their complex nervous system, allowing them to change color and texture in the blink of an eye.

2 Cone Snail

You wouldn't normally associate snails with being poisonous, but this reef dwelling specie takes the cake. Hiding under the shell is a modified tooth that the snail shoots out like a harpoon to snare fish.

This tooth is hollow, barbed and lined with poison to instantly paralyze fish. However this poison is strong enough to kill a grown man. Members of the Conus specie have more than one harpoon, locked and ready to go at any one time. The harpoons fired by larger snails can pierce through gloves and wet suits, so humans are advised not to pick up these snails.

1 The Brain-Eating Amoeba

via:strangesounds.org

Naegleria fowleri is a free-living amoeba found in warm bodies of fresh water, soil and unchlorinated swimming pools. Known to cause primary amoebic meningoencephalitis (PAM), it is feared for its high mortality rate. Victims infected by PAM complain of a headache within the first two weeks of infection. As the amoeba continues to feed on nervous tissue, victims experience nausea, vomiting, and a stiff neck. Confusion and hallucinations follow until the victim drops dead after another five days.

This is a global killer as PAM has been reported in India, Iran, Taiwan, New Zealand, the UK, Venezuela.

In nature, bigger size, more teeth, sharpest claws don't necessarily make you the baddest. Humans should respect all creatures, great and small. You never know who is packing the biggest punch.
