There are many different types of fish in Antarctica
which you can find very interesting.
The ice fish is interesting
because it has antifreeze which keeps it's body from
freezing.
There is another fish called
cod. It is very big and can grow to the average size
of 18-39 inches. The cod weighs up to 10-11 pounds.
The cod is usually more on the grayer side. and
migrates usually to the Atlantic and Pacific oceans.
The cod also has antifreeze in it's body which keeps
it from freezing during the Antarctic
winters.
All fish have a very simple
structure with gills, a dorsal fin, pectoral fins, and
a tail fin. The color of fish is usually gray, red,
black, or silver. Most of the fish there eat krill.
Krill is a type of plankton which whales eat also. The
fish also eat plants and crabs.
Unlike whales and sharks, the
fish can go very deep down under water. Fish usually
swim in schools for protection. The fish stay in
Antarctica in the summer and the spring and migrate in
the fall and the winter. These fish migrate to almost
all of the oceans, but some fish just go farther away
from Antarctica. When they migrate to the other
oceans, they lay 5,000 to 5,000,000 eggs.
