How do elephant seals stay underwater for so long?
Special properties of an oxygen-binding protein in the muscles of marine mammals, such as seals, whales and dolphins, are the reason these animals can hold their breath underwater for long periods of time, according to a new study.
Can elephants hold their breath underwater?
Just keep swimming.
Like most other mammals, elephants are natural-born swimmers. They can swim completely submerged underwater, using their trunks to breathe. If they do get tired, the elephants’ massive bodies allow them to easily float and rest—it’s nearly impossible for them to drown!
