Answers
Answer:
Polar bears are strong swimmers; they swim across bays or wide leads without hesitation. They can swim for several hours at a time over long distances. They've been tracked swimming continuously for 100 km (62 mi.).
A polar bear's front paws propel them through the water dog-paddle style. The hind feet and legs are held flat and are used as rudders.
A thick layer of fat, up to 11 cm (4.3 in.) thick, keeps the polar bear warm while swimming in cold water.
Polar bears can obtain a swimming speed of 10 kph (6.2 mph).
A polar bear's nostrils close when under water.
Diving
Polar bears make shallow dives when stalking prey, navigating ice floes, or searching for kelp.
Polar bears usually swim under water at depths of only about 3-4.5 m (9.8-14.8 ft.). They can remain submerged
