"Their movements were very particular"

So far, that record goes to the Cuvier's beaked whale, a medium-sized whale that is known for its long, deep dives. There's a lot that is unknown about the oceans, but with developments in research technologies, we're learning more each day. One of the most useful developments in recent years has been the use of tags to track an animal's movements.

It was through using a satellite tag that researchers Schorr, et.al. (2014) discovered this beaked whale's amazing breath-holding capabilities. Of the coast of California, eight Cuvier's beaked whales were tagged. During the study, the longest dive recorded was 138 minutes. This was also the deepest dive recorded—the whale dove more than 9,800 feet.

Until this study, southern elephant seals were thought to be the big winners in the breath-holding Olympics. Female elephant seals have been recorded holding their breath for 2 hours and diving more than 4,000 feet.
