If you were to look at
the ocean in layers different species would be on different
layers. One the top layer would be the Pilot whale and the
Killer whale. One the second layer there is the Right whale
and the Humpback whale. Going one layer lower would be the
Narwhal, the Fin whale, and the Beluga whale. Going even
lower than would be the Gray whale and the Blue whale. Then
finally at the bottom of the ocean are the Giant Bottlenose
whale and the Sperm whale.

The smallest out of all these
whales is the Beluga whale at the length of about 4.6m or fifteen
feet. The biggest whale out of all of the whales mentioned above is
the blue whale and it is at about 30.5m or one hundred
feet.
Whales are able to swim at
about 35 miles per hour. Whales stay up on the surface most of the
time but can dive down approximately a half a mile. By looking at
skeletons scientists discovered that the ancestors of whales once
lived on land.
Adult Beluga whales
travel in groups called pods. To communicate whales make two
different types of basic sounds. The low pitch sounds, such
as barks, whistles, screams, and moans. These are the sounds
as humans hear them but to whales they are a normal
way of communicating.
The Blue
whale is the largest mammal that ever lived. They
are one hundred feet long. The young born in April
or May, are about twenty-three feet long
at birth. They can reach to a
length of sixty feet by their first
summer.
