This incredible, rare footage was uploaded by Ronald Raasch.

It shows a team of divers catching a rare glimpse of a gigantic transparent egg sac containing a large number of baby squid.

The stunning underwater video was captured by Ronald, 48, when he was diving with two colleagues from the research vessel REV ocean in the cold waters off Ørsta, Norway on October 5 2019.

the team of divers were making their way back to shore after visiting a World War II shipwreck about 200 metres from the coast, when they had the once-in-a-lifetime encounter with the mysterious object.

Floating 17 metres below the surface and around 15 metres above the sea bed, the giant, transparent orb was quickly identified by the professionals as a 10-armed squid's egg sac.

Truly brilliant!
