Whales use a sound similar to Kim Kardashian's 'vocal fry' to hunt deep sea prey, say scientists

• Toothed whales can use vocal registers like humans to communicate and hunt. 
• Like Kim Kardashian, whales have a "vocal fry" which can be used to find prey in deep sea.
• At that depth, the whales' lungs collapse, so they use air trapped in their nose to communicate.

One of Kim Kardashian's trademarks is her vocal fry, a creaky voice affectation that studies have suggested is deeply polarising for humans.
