Water Monitor
Just wait until you hear this amazing but horrifying fun fact about the water monitor. This creature is actually capable of smelling underwater or underground with the use of its tongues! After that, this animal will do whatever it takes to catch its prey. It will swim, climb, and run if that is what it takes.
Anaconda
There have been anaconda snakes that grew as long as 30 feet! This is a huge animal whose size and weight make it even more dangerous than it already is. These creatures will catch and bite prey, but that is not the worst part just yet. Once it does that, it will then crush them to death! Ouch.
