The Most Horrifying Sea Monsters To Ever Terrorize The Ocean

The ocean is massive - and the creatures lurking beneath its surface can grow to sizes that would be impossible on land. Whales are the largest living creatures in the sea, but these gentle giants were preceded by some of the scariest sea monsters of all time. The fossil record is full of scary sea animals that would make Jaws look like a little guppy in comparison - so many that it’s a miracle that none of them are alive today (maybe). 

Giant fish, sharks, and reptiles dominated the oceans for millions of years, becoming the apex predators of one of the craziest and most diverse environments on our planet. Sea scorpions the size of crocodiles swam in the same waters as massive armored fish who could bite a great white in half. The oldest sea creatures were more terrifying than anything cartographers ever doodled onto their maps. These are some of the deadliest creatures of all time, the ones who epitomize the phrase “there’s always a bigger fish.”
