In fact, crocodilians can spend hours underwater without coming up for a breath of air. I have personally observed a female saltwater crocodile spend nearly two hours submerged. After a short period of time underwater, the oxygen in the lungs is gone (crocodilians will typically expel air in order to sink, anyways).
How long can a crocodile stay under water?
CROCODILES can hold their breath underwater for more than an hour. Researchers in Cambridge have now shown that this ability depends on a tiny fragment of the animal’s haemoglobin the protein that carries oxygen from the lungs to the rest of the body.
Crocodiles cannot breathe underwater: they breathe air, just like people. When they are not active, they can hold their breath for a maximum of about two hours underwater before drowning. Normally, when underwater, they are active and can hold their breath for a maximum of 20 minutes to one hour.
How long does a crocodile stay under water?

Crocodiles can submerge and remain underwater for a variety of reasons. In most voluntary dives, crocodiles stay underwater for between 10 to 15 minutes. If the crocodile is trying to hide from a threat, dive length may be longer, up to 30 minutes or more.
Can a alligator or crocodile bite while under water?
YES. While it is widely believed that crocodilians cannot open their mouths — and therefore cannot attack — underwater, this is most emphatically not true. They have a palatal valve in their throat that prevents water from entering. Most crocodilian attacks occur underwater. Definitely yes.

Crocodiles use a waste product of metabolism – the bicarbonate ions formed … CROCODILES can hold their breath underwater for more than an hour.
