Depends on what you mean by live underwater.
Whales, manatees and dolphins are all mammals that live their whole life mostly underwater. They are still air-breathing though, so they have to surface veryregularly to breathe.
No animal mammal can live entirely underwater.
Us humans could potentially live entirely underwater by using technology to bring some surface conditions(=breathable air) with us into the depths.
Many kind of aquatic mammals can live under water for some time but they have to come on surface to breath as they are lungs breathers ,eg whales , otters , seals , walruses , sea lions , beavers etc.
Whales, dolphins, porpoise, seals, sea lions, walrus, dugong and manatee all live under water
