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.
A penguin can stay underwater for about 15 minutes and go to a depth of 1700 feet.
I think a seventh grader should study at least thirty minutes a day.
Yes. They do spend most of their life underwater as nympths.
only half their life
As long as they want!! Children love to be outdoors the longer the better! At least have them spend a half an hour to forty-five minutes a day.
You should exercise at least 30 minutes a day. But if you don't have time to exercise for 30 minutes altogether you can split the time into intervals. But make sure they are at least 10 minutes long because if you exercise for less than 10 minutes it will not effect you.
