The ocean covers 70% of planet Earth, so it’s only natural that it’s home to millions of creatures. And from that percentage, we have only explored a mere 20%, leaving the rest of the 80% completely unexplored. This means that there is a large number of species that humans don’t know about and have never seen. So, each year, scientists keep discovering new creatures from the deep sea that make us feel smaller and smaller.

1. Atlantic sturgeon

This unique type of sturgeon belongs to the ancient family of Acipenseridae. What is truly amazing about this species is that it has 5 rows of bony plates instead of scales. These plates are there in order to protect the animal from possible attacks. And it’s the reason why this sturgeon wasn’t immediately devoured by a flock of seagulls after being washed up on the beach.

2. The tuna with huge bites

A professional fisherman caught this tuna only to discover these large bite marks all over the fish’s body. Some people rushed to say that these couldn’t be from another fish or shark, as they were too round. However, the man who caught the tuna, Trampman Bermagui, said that they were made by the cookiecutter shark. This specific shark takes large bites from its prey without killing it.

3. A transparent creature

Trapman Bermagui also discovered this deep sea rough skin shark that lives 650 meters below sea level. While many people confused it with a cookiecutter shark, the Australian man let everyone know that this was not the case. According to him, this shark is also known as an endeavour dog shark, and they catch them during wintertime.

5. Pacific viperfish
