If you're looking for a feel-good story of the last year. Maybe this whale could help. Cuvier's beaked whale or the goose-beaked whale (Ziphius cavirostris).

Look at the picture, it looks like a swimming sausage and that whale is awesome!

In March scientists off the coast of California observed a pod of eight Cuvier whales plunging up to 2.9 kilometers beneath the surface of the sea and staying down there for up to 138 minutes.

These were the deepest and longest dives ever recorded among mammals!

How Experts Did the Research

Now, the 5 to 7 meter long Cuvier are notoriously hard to study. They stay far away from the shore and biologist can't get close enough to get tag with them, like what humans do with other whales.

So, from a distance scientists had air rifles to attach trackers with transmitters that record depth to the whales. They haven't quite figured out how the Cuvier's whales can stay so low, for so long.

Most marine mammals have a rib cages that can actually fold and claps the lungs reducing air pockets and allowing them to make the most of every breath.
Beat the Record!
The Cuvier's dive shattered a record previously held by the Southern elephant seal which lives off the coast of Antarctica and can descend 2.4 kilometers and stay there for 120 minutes.
