10. Remipede
Remipedes are tiny critters that resemble white centipedes. They have a long-segmented body with lots of swimming legs. This creature is found in the caves of Mexico and parts of Central America. They were first classified scientifically in the 1980s, but the details were still sketchy because their terrain is challenging to work in. We know that these blind predators feed on the shrimps that make their way to their underground pools. Scientists from the National History Museum discovered that this crustacean has a needle-like fang on each side of its head surrounded by muscles that can pump fluid out.
Deep inside their body is a gland that produces venom that is stored in their reservoir. These toxins are odd compared to other arthropods. While the poisons in other spiders have neurotoxic proteins, the Remipedes toxic cocktail is dominated by enzymes that break their prey's exoskeleton. Its efficacy is compared to that of a viper, and their lifestyle and environment pressured them into going toxic.

9. Japanese spider crab
The fear of spiders is one of the most common phobias in the world. The chances are that you or someone you know has it. This fear isn't entirely out of place, especially when you learn about a creature like the Japanese spider crab. Crabs aren't that dangerous or scary, but this species is in a world of its own. They are the largest of their kind and live longer than humans. There are confirmed cases where they chop off human fingers. Although they are not hunters, they feed on kelp, mollusks, slow-moving invertebrates, and the dead bodies of animals moving about in the water.
Legend has it that they drag sailors overboard and eat them alive in the ocean depths. While this may not be true, they're known to devour the bodies of dead sailors. Although they're found between 150 to 300 feet down, you should be worried because they can venture into shallow waters when it is time to mate. You may never see these decorator crabs coming your way as they are skilled in the business of disguise.

8. The mantis shrimp
The Mantis shrimp is an aggressive crustacean that lives in the subtropical and tropical waters of the Pacific oceans between East Africa and Hawaii. They are notorious for their striking force, which is likened to a 2.2 caliber rifle. Their fists are spring-loaded and can accelerate from their body at 50mph. The force is enough to smash through crab shells, and if humans had such powers, they would be able to punch through steel. There are over 450 species, with the most notorious one being the Peacock mantis shrimp. They grow to about 4 inches, with some recorded to be as large as 18 inches.
They are solitary and, as such, spend most of their time hiding in rocks and burrowing in the sea bed. They are violent predators whose diet depends mainly on the species. Generally, they eat snails, clams, crabs, fish, squid, and shrimp. Surprisingly, they even eat animals much more prominent than them. Their photoreceptors are three times more effective than humans, suggesting that they are great at differentiating colors.

7. Sand fleas
Sand fleas are known for names like suthis, juggers, picos, or niguas. The CDC says that females pose more health risks to humans. While the males feed on warm-blooded mammals like humans, their female counterparts burrow into the skin. What if I told you that humans help them reproduce? Here's how it works. When the female sand flea burrows into the skin, the males come there to mate with them briefly. After that, the eggs numbering about 100 drop to the ground, and both fleas join them.
You don't even notice when all these are happening because this creature is small. You start to develop symptoms hours later. It may result in lesions that may cause difficulty in walking. The opening caused by burrowing could expose the victim to infections, and in severe cases, the leg could be amputated. Treatment is based on the extent of the damage. They are found on beaches across the Caribbean, South America, and Africa.
