10 Creatures That Are Terrifying Killers



Sea Lamprey

The Sea Lamprey is a truly disgusting creature. The highly primitive aquatic vertebrate looks something like a giant leech. These eel-like creatures do not have any limbs, but instead latch onto other aquatic creatures and feed off of them.

Candiru

The Candiru is truly terrifying, as these tiny fish have been known to swim up the urethra of a grown man and release their barbs into the flesh. They can even get into a human’s lungs, where they suck blood until the individual dies.
