What special adaptations do manatees have that allow them to stay underwater longer than the average land-dwelling mammal?
Manatees are not land-dwelling, they are water-dwelling mammals therefore their lungs are bigger so they can stay underwater longer.
What special adaptations do manatees have that that allow them to stay under water longer than the average land-dwelling mammal?
. Manatees, like other aquatic mammals, do most of their feeding underwater and must be able to hold their breath long enough to feed efficiently. Aquatic mammals have a number of adaptations that allow them to stay under water longer than the average land-dwelling mammal. Both the lungs and diaphragm of a manatee extend the length of the body cavity and so are oriented in the same horizontal plane as the manatee in the water. This arrangement is important for buoyancy control. An unusual anatomical feature of sirenians is that each lung is in a separate cavity. Instead of one diaphragm like people, manatees have separate "hemi-diaphragms." Besides breathing, the lungs help the manatee with buoyancy control. Manatees replace a large percentage of air in their lungs with each breath and can therefore prolong intervals between breaths. In fact, studies have shown that manatees can renew about 90% of the air in their lungs in a single breath as compared to humans at rest who generally renew about 10%
How do manatees stay under water longer than any other mammal?
They don't stay underwater longer than whales.
Why do centaceans also known as manatees have useless tiny hips and legs?
You are mistaken there; cetaceans are dolphins and whales, not manatees; manatees are known as sirenians. They have useless hips and hind legs because they are so well adapted to a marine lifestyle and they no longer walk on land.
Is it true that the bigger the animal the longer it lives?
Yes that is true that the bigger the animal the longer it lives.
What is a balloon animal?

Do sea lions live longer in captivity or wild?
Sea Lions live longer in captivity. An average life span for a sea lion in the wild is 18 years and 23 in captivity. But, that does not mean an animal in the wild can't live longer than one in captivity.
Why can a horse live longer than a cow?
It is simply the nature of the individual species of animal. I am speaking here of "average" lifespan for that particular animal. For a horse, it is 22-25 years. For an elephant, about 60 years. For a dog, 12-14 years.
