The Cuvier's beaked whale is the undisputed champion of the long, deep dive. In a study released this week, Erin Falcone and her team recorded a record-shattering dive: one whale held its breath for an astounding two hours and 43 minutes.
"When I first saw the data, I thought 'is there any limit to what this animal can do'?" Falcone tells Axios. (When she recorded a two hours and 17 minute dive in 2014, she said, "it blew us out of the water.")
