Yeah, sperm whales can do 90 minutes and the longest recorded beaked whale dive is over two hours.

Heck, the human record is something like 20 minutes, by some free diver.

To clarify, the static apnea record breathing normal air beforehand is just under 12 minutes.

The record you are referring to involves breathing pure oxygen beforehand, is 24 minutes, and is nonetheless amazing.

I'd always thought the egg laying, electrolocating Platypus was the strangest mammal:

"The platypus feeds by neither sight nor smell, closing its eyes, ears, and nose each time it dives. Rather, when it digs in the bottom of streams with its bill, its electroreceptors detect tiny electric currents generated by muscular contractions of its prey"

FWIW geckos need quantum mechanics just to walk.

...and I, for one, welcome our new platypus-gecko hybrid overlords!

Don't sharks do this, too?

Yes, using the Ampullae of Lorenzini in their snout.

Too cool. Thanks!

Wales go without breathing, not without oxygen. I'm not sure which category this fits into but it soudns like they just about die but then revive:

> But naked mole-rats? Although they lose consciousness after 30 seconds, and their heart rates crash after two minutes, and they stop breathing entirely after seven minutes, they can survive for a ridiculous 18 minutes.
