FAST SWIMMERS: SEALS
These cute animals, which most of you know from television and from
circuses, spend most of their lives in the water. They are very good
swimmers and divers. They are just as happy and comfortable in water
and on glaciers as we are on land. Even in spring, the temperature of
their habitat remains around –5 degrees Centigrade (23F). While we
have to put on clothes and take many precautions, they don't feel cold
at all. Because their fur and the fat they store in their body prevent them
from being cold.
