Breathtaking pictures taken by Russian diver, zoologist and sea fauna researcher Alexander Semenov show us the spectacular underwater creatures, many of which are very rare and uncommon.

These ocean creatures are very creepy and more terrifying than sharks. They are deadly, incredibly large, and they all are very scary.

Giant Halibut

These underwater sea creatures are both unusual and beautiful. It is hard to imagine that something so incredible could live and thrive underwater. Some have names you won’t be able to pronounce and some are very common.

This Christmas tree worm

These are the weirdest creatures ever found by people. Most of them seem to be real.

Strange and amazing deep-sea creatures were discovered by scientists during their 6-week expedition in the Atlantic Ocean. They are stars that walk on their unusual network of arms, new species of sea cucumbers, electric worms and other most unbelievable sea inhabitants. The voyage was the last of the MAR-ECO project that consisted of several biological surveys of unexplored Mid-Atlantic Ridge.

Enjoy this interesting compilation of transparent creatures that look simply amazing on these photos.
