• The black skin helps to absorb heat from the sun.• Small ears reduce heat loss• Toes which are joined by skin (webbed feet) allow the bears to swim more
easily without getting tired. The waterproof coat also helps with swimming by keeping the bear dry.
• Strong curved claws are used to catch prey and tear up food as well as grip the ice.
• Hair on the soles of their feet and between their toes help the bear to grip the ice when they are walking or running without slipping.
• Large feet help to spread their weight, so that they do not fall through thin ice.
