We all enjoy movies of Hollywood that are particularly focused on monsters, sea animals, unknown species of the earth and vampires, but it is time to know about most terrifying sea monsters that lived in oceans for many years. Below you can find the details of top 10 largest monsters that were very petrifying.

10. Shastasaurus

When you look at the picture of Shastasurus, you think it is similar to dolphins of this era. However, these marina predators were living in marine over 200 million year ago. They could grow to more than 60 feet. These largest creatures of pre-historic time weren’t very dreadful as they mainly consumed fish.

9. Megalodon

These largest creatures can be named as ancestors of modern era sharks. It is claimed that these monsters were existing 25 to 1.5 million years ago, at the same time when we were reading about the existence of dinosaur. They swam in the warm water oceans that were present before the last ice age.

8. Dakosaurus

If you want to see a beast of Jurassic period then you need to look at Dakosaurus. It was one of the top predators in the sea. Its fossil was first explored in the Germany. Fossil consists of a reptilian-cum-fish style body. It fossils also discovered in many other countries of World such as Russia, England and Argentina. The length of Dakosaurus was around 16 feet. The structure of its teeth clearly demonstrates that it was a terrifying monster of its time.

7. Basilosaurus

You can call them as ancestor of modern day whale. They could reach 50 to 85 feet in length. According to a study on Basilosaurus, they didn’t possess cognitive skills of modern sharks. So, it means that if the people dove on dry land of sea then they were not chasing them out. However, the body structure of this largest creature was terrifying and it would be a difficult experience for prehistoric swimmers to swim close to Basilosaurus region.

6. Thalassomedon

It belonged to Pliosaur species. Pliosaur is a Greek word and its meaning is “Lord of Sea”. When you look at the picture, you come to know that this name suits to Thalssomedon, the monsters that could reach to 40 feet in length. It had flippers that were more than 6 feet long. These long flippers allowed this predator to swim efficiently and to catch its target in no time.

5. Nothosaurus

You can call them aggressive hunters who were featured with sharp pointing teeth. They ate big fish and squid. Although they could reach to 13 feet in length only but they could catch prey very quickly and surprisingly.

These were among the top predators of Jurassic period as they had dominant position in food chain. This largest creature could reach to 20 feet in length and half length of its body was comprised of jaws with big and sharp teeth. Their fossils were discovered in the seas around Europe.

2.Livyatan Melvillei

This giant whale had 10 feet long head. It ate other whales and no doubt, it was a scary whale of its time. According to fossils evidence, it was found at the same time when Megaldon were present. That’s mean it had to face tough competition with a strong and largest predators of its time.


1. Mosasaurus

It was indeed the most dreadful organism of Cretaceous period. It could reach to 50 feet in length. The head of Mosausaurs was exactly matched with crocodile’s head; the main difference between both species was sharp razor form teeth.
