Guess how long it remain down . Go on , reckon . 30 minutes ? 60 minute ? 90 minutes ? Nope . More . Keep guessing .

Humans have been be intimate to hold their intimation underwater for over 20 transactions . That ’s a lot to you and me , but to many of Earth ’s water - dwell mammals 20 minutes is a joke , like dunking your head underwater . Take the southerly elephant stamp for case — these massive carnivorans routinely hunt squid and fish that live century of meters beneath the ocean aerofoil . Doing so requires them to go incredible lengths of time without air . Their dives have been known to plunge over a mile beneath the waves and last up to 120 minutes long .

And , for a while at least , two time of day was the disk for the longest mammalian dive . No longer . agree to findings publishedin the latest effect of PLoS ONE , the young disc holder is the Cuvier ’s beaked heavyweight . A squad lead by researcher Gregory Schorr used orbiter - linked tags to record the diving conduct and placement of eight members of the elusive species for up to three calendar month , off the Southern California sea-coast . When they were finish , Schorr ’s team had tracked one giant that dove to a depth of 9,816 feet ( 2,992 meters ) , and a instant that stayed down for a astounding 138 second .
“ It ’s remarkable to guess these social , warm - blooded mammals actively go after quarry in the darkness at such astounding depth , literally miles off from their most basic physiologic need : air , ” said Schorr in a press release .
Schorr ’s squad was monitoring the species to easily understand why nearly 70 % of the record nautical mammal strandings assort with military sonar operations involve Cuvier ’s beaked giant . Such strandings have occurred on beach in the Mediterranean Sea , the Canary Islands , and the Bahamas , but so far none have been reported in southern California – the site of a Navy sonar testing area , and where Schorr ’s squad conducted its study .
