Megalodon, The Whale-Sized Shark
Measuring at more than 50 feet long, the megalodon was the largest known shark of all time. Their jaws alone were large enough for a full-grown person to walk through with ease, and they used those jaws to hunt whales. To put it in perspective, researcher Peter Klimey with the University of California at Davis said, "A great white is about the size of the clasper, or penis, of a male megalodon.”
Scientists believe that megalodons hunted whales by first ripping off their tails and fins - immobilizing their prey so they could more easily feast. It is also believed that the extinction of these giant sharks is what allowed whales to reach the enormous sizes that they are known for today. Researchers confirmed that the last megalodon died only 2.6 million years ago, right around the same time the evolution of the first humans began to take place.
Dunkleosteus, An Armored Death Machine
This ancient fish lived 400 million years ago, but its bite has stood the test of time. Scientists believe the Dunkleosteus had the strongest bite of any fish ever discovered - one that could be compared to the bite of a Tyrannosaurus rex. Scientists have crunched the numbers and determined that, just at the tip of its fang, this fish’s bite could measure at 8,000 pounds per square inch. They were absolute apex predators, preying on sharks and basically anything it could catch (everything). Dunkleosteus was also 33 feet long from tooth to tail and covered in thick armor-like plating, making it one of the ocean’s first giant predators.
Liopleurodon, A Reptilien Behemoth
The Liopleurodon was a giant marine reptile and one of the fiercest predators of the Jurassic period. These massive sea monsters could grow up to 30 feet in length (although some fossils suggest even larger sizes) and had sizeable teeth that would have made a quick meal out of most marine life.
Despite its size, scientists estimate this reptile probably swam surprisingly fast, and like many sharks, Liopleurodon had an excellent sense of smell, which it used to locate prey. While this all may sound intimidating, chances are Liopleurodon was not even the largest animal in its class; that title most likely goes to Kronosaurus.
Mosasaurus, A Ferocious Prehistoric Predator
The Mosasaurus became an international celebrity after its breakout performance in Jurassic World, and the real-life version is just as impressive. These giant reptiles could likely swallow most of their prey whole but preferred slicing meals into bite-sized morsels with their backward-bending teeth.
Paleontologists have been studying these animals for years, and a recent discovery has shed new light on the early lives of mosasaurs. Researchers examined two baby mosasaurs and learned that they actually spent their early lives in the open ocean. This discovery has led some scientists to believe that mosasaurs gave birth to live young.
Jaekelopterus, A Sea Scorpion Bigger Than You
Jaekelopterus reigned as an apex predator nearly 400 million years ago and was probably willing to eat anything smaller than itself - including members of its own species. These arthropods grew to over eight feet long and had huge, spiked claws that could ensnare fish with ease. Experts believe the Jaekelopterus ambushed prey with its claws before tearing the meal apart. Jaekelopterus is the largest discovered species of arthropod, a group that includes insects, arachnids, lobsters, and crabs.
Leedsichthys, The Largest Fish Ever
Even though scientists originally overestimated the size of this giant fish by whopping 40 feet, it is still considered to be the largest bony fish ever discovered. In fact, the Leedsichthys was so big that its gill bones have sometimes been mistaken for the bones of pterosaurs. Although they could grow up to 55 feet in length, their great size didn't make them great hunters. Like many sea giants, Leedsichthys survived by feeding on some of the smallest creatures in the sea: Plankton probably made up a majority of their diet, although it’s difficult to pinpoint the feeding habits of an extinct animal. Scientists believe that, even though the largest discovered specimen was around 55 feet, that these animals could likely have grown to be even bigger.
Livyatan Melvillei, The Whale That Ate Whales
Named after Herman Melville, the author of Moby Dick, Livyatan melvillei was a massive species of sperm whale that is believed to have preyed on primarily baleen whales. This creature lived only 12-13 million years ago, which is frighteningly recent when it comes to the span of geological time. And while it is estimated to have been about the size of a modern sperm whale, it had foot-long teeth that suggest its food of choice was quite a bit bigger than your average squid.
