The depths of the ocean are a mysterious place where you cannot predict when and where you will meet unusual creatures. A few days ago, near the coast of Cornwall, England, there was a strange collision between a huge jellyfish and a human.

Diving under the water biologist Lizzie Daly came face to face with this never-before-seen creature. This barrel-shaped jellyfish was the size of a human. This type of jellyfish is the largest.

“It is known that these jellyfish can reach this size, but it is one thing to hear about these underwater creatures, and completely another to meet them face to face,” Daily told CBS News.

Incredible! Yesterday our underwater group dived in Falmouth to finish the project #WildOceanWeek. You won’t believe it, but having descended into the water, we stumbled upon an unusual jellyfish – it was huge. Jellyfish of this species are called barrel-shaped! — wrote the diver on Twitter.

Lizzy was diving with marine photographer Dan Abbott and he managed to capture the jellyfish on camera. Lizzy admitted that the expedition exceeded all her expectations.

WildOceanWeek is a demonstration of the real underwater world. Divers diving into the water try to convey the atmosphere of this world as much as possible. Sometimes divers have to swim even with sharks and see various strange creatures.
