Yesterday a 45-second video clip of a True’s beaked whale (Mesoplodon mirus) was released to the world, along with a study published in the scientific journal PeerJ. This was the first underwater video ever recorded of this particular whale species, and one of only a handful of live sightings. True’s beaked whales can hold their breaths for hours and are believed to dive as deep as 10,000 feet.

The bodies of these elusive whales are extremely hydrodynamic and their sides contain pockets for them to tuck their flippers in for even more hydrodynamic.
