the bulk of their time yes
They don't! :P C.H.

Polar bears eat seals, and seals are found in the sea.
Seals do spend a lot of time in water, but they don't lay eggs.
Sea otters most of their time in the water. Here this should help- 65% in water 35% on land.
They dive in the water and catch fish with their sharp teeth! They can dive for a long time and they can go to deep depths!! I was thinking of this too and i learned that from some other webs
Harp seals spend most of their time in cold water oceans.
Seals spend a lot of time in the water hunting food. They come to land to bask and rest, mate and give birth. Probably, roughly, it is half in the water and half on land.
Antarctica is a continent and seals are sea mammals that live in liquid water. Around Antarctica in the Southern Ocean, you can find Weddell Seals and Leopard Seals. These animals carry a layer of fat under their skin which preserves their internal body heat regardless of where they swim.
Seals hunt fish, in the water, all the time
Harp seals live in northern Canada. Im not sure if that is considered tundra.
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.
