A trio of divers off the western coast of Norway had a close encounter with a drifting gelatinous blob — a squid’s egg sac as big as an adult human.

A video captured shows a diver slowly circling a spherical blob surrounded by a transparent membrane, with a dark mass suspended inside.

As the diver swam around the blob, his flashlight lit up its interior. Inside were numerous tiny spheres — eggs holding baby squid, estimated to number in the hundreds of thousands.
