Alaskan
sealife.
In
the frigidly cold environment of Alaska you would think that very little
sealife would survive here. In fact, the very opposite is true. The primary
reason for this is oxygen.
Cold
water holds more oxygen than warm water. This oxygen is the foundation
for life in this ecosystem. Oxygen makes these waters phenomenally rich
with nutrients that allow bait fish and other food animals to flourish.
This literally feeds the waters off Alaska and all of the West Coast of
the United States as these nutrient rich waters move south with the ocean
currents. A good example of how rich these waters are is to consider the
Gray whale. The Gray whale migrates over a 1,000 miles each year to the
comparatively warm and protected calving areas found in Baja California.
They don't eat for months on this journey, preferring to wait for the
abundant food sources found in Alaska to eat again.
