This Mesmerising Underwater Blob Is Actually A Huge, Rare Mass Of Squid Eggs

A team of divers filmed a rare glimpse of a huge transparent egg sac containing hundreds of thousands of baby squid. The stunning underwater video was filmed by Ronald Raasch, 48, as he was diving with two other team members from the research vessel REV Ocean in the cold waters outside Ørsta, Norway.

Humboldt squid (Dosidicus gigas) egg masses, on the other hand, are more like a transparent blob, as is that of Gould's squid (Nototodarus gouldi), the Japanese flying squid (Todarodes pacificus), and the neon flying squid (Ommastrephes bartramii), one of which measuring 4 metres (13 feet) across was filmed by National Geographic in 2015.
