In Florida in the US we call them coots. Not sure if this is a proper name or just local lingo.
Three 20-minute periods.
Hippos can't "breath" underwater but they can hold their breath for long periods of time.
no but they can hold their breathe for long periods of time
Some kinds can actually swim underwater, such as ducks and geese. Other kinds of birds bathe in water and can put their heads briefly under water.
Yes it is, as if you stay underwater for too long, your lungs can't take it, and you may choke/ faint. Only a few mammals (whales, dolphins, porpoises, etc.) can stay underwater for long periods of time.
Probably a member of the Cormorant family. These are fish eating birds well known for their underwater swimming abilities. Loons are a member of this family.

so it has a longer time of having air
Seals are correctly defined as aquatic mammals, in that they breathe air in the same way as we do, but spend at least half of their lives in water and are able to hold their breath for long periods of time whilst swimming underwater.
Myoglobin enables the marine mammals to be able to hold their breath for extended periods of time underwater. The beaver has been reported to hold its breath underwater for about 15 minutes.
First, if you see an animal go under and you know its a duck and he's been down for more than 10 seconds you get into that pond and get him out: he needs help! Second, a duck-like bird that can stay underwater long is a loon. The waterfowl that can stay underwater the longest has to be the cormorant. I've timed one who stayed underwater for a total of two minutes!
It's certainly possible. Staring at the small screen for long periods can bring on a headache.
