A team of divers that were in the ocean to explore a sunken World War II ship off the Norweigian, coast, but what they found was something that was really mysterious.

As the divers were making their way back to the shore, Ronald Raasch, Nils Baadness and Brynjar Aarnseth came face to face with a giant floating mysterious egg.

The mysterious egg was around 17 meters big and was found below the surface and appeared to be see-through.

The divers turned their flashlights on and realized that the sphere was filled with hundreds of thousands of little animals.

Nils Baadness, a diver, said, “At first I thought it was a giant jellyfish, but when we came a bit closer, we saw that this was [like] nothing else we had seen before.”

He added, “It was amazing.”

Baadness recognized the sphere as a giant squid egg, which he only had seen on the TV.

He said, “To see it in person was a once-in-a-lifetime moment.”

Ronald Raasch, who is part of the REV Ocean Research Team, filmed the entire incident and posted it on social media.

The team has been researching these mysterious egg sacs.

The REV Ocean Research Team has collected 4 samples from Norwegian waters so far this year.

Halldis Ringvold, a researcher with Sea Snack Norway’s Gelatinous Sphere Project, said, “They were genetically tested, and turned out to match the 10-armed squid Illex coindetii (southern shortfin squid).”

He added, “The jelly ball from the video … has not been genetically tested, but is similar to the other jelly balls which have been tested.”

The Southern Shortfin Squid, which is usually found in the North Atlantic Ocean and the Mediterranean Sea, which is around 8 and 16 inches long, which doesn’t include their legs.

The squid is capable of laying a giant sphere, which is around one meter in diameter. The eggs are filled with eggs.

Baadness said, “We were very lucky to be there at the right place at the right time. We will probably not experience this ever again.”

The divers said the experience is something they will never forget in their lives.
