While on an educational trip in the Azores back in 2013, students captured footage of one of the most rarely seen animals on Earth. Years later, the True’s beaked whale is making its film debut  in the journal PeerJ, along with a detailed study of the whale. The goal is to get a better idea of the threat humans pose to deep sea diving mammals. These whales reach up to 17 feet long and can likely dive thousands of feet underwater for several hours at a time without a single breath. Before the footage surfaced, most scientists got their information from carcasses, so this is a big development in understanding the True’s beaked whale.
