The blue whale heart is the size of a small car, the major arteries leading from
the heart a small child can stand it! This is an example about amazing whale
fact. I focused about previous amazing facts on whales, dolphins, and porpoises
in this research paper. As we knows, whales are one of the most intelligent
mammal in the ocean. There are two kinds of whale, one is toothed whales and the
other one is baleen whale. The third largest whale in the world is the sperm
whale. It is the biggest toothed whale in the world. In Latin, physeter
macrocephalus means sperm whale. The sperm whale has the biggest forehead of the
whales. It has a long narrow jaw. The sperm whale smells through its blowhole.
The brain of the sperm whale is the biggest brain in the world. It weights
twenty pounds . It can be used like a computer. The sperm whale has ears but
very little hair. Sperm whale can dive a mile under the water. Two thousand feet
under the surface, a sperm whale might appear. The sperm whale can go underwater
for more than half an hour. In addition, many toothed whales are believed to use
their sonar capabilities to stun their prey with a gsonic pulseh. The narwhal,
an unusual toothed whale with a tooth piecing the upper lip, is believed to be
the basis of the legendary unicorn. Southern right whales have been seen to
raise their flukes in the air and use them as sails. Grey whales are able to
swim in water as shallow as 6 feet! There are four species of dolphins that
inhabit fresh water rivers. Some species of whale lice, small crustaceans
similar to terrestrial lice, can be found only on one type of whale. Whaling
still occurs today with Japan and Norway being the primary hunters. Fin whales
are the second largest animal ever to live on earth. They have been measured to
over 80 feet long in Antarctic waters. Fin whales are the only known mammal to
have regular asymmetrical coloration. The right side of their lower jaw and
baleen are white, while the left side is black. The tongue has the reverse
coloration. It is thought that they use the white color to startle and stun fish
schools when they feed. There is no known winter breeding ground for fin whales
anywhere in the world. Scientists think they may go offshore and disperse during
the winter. Reproduction is seasonal, but no concentration area is known. The
only natural predator of humpback whales is the killer whale (orcas), and
possibly sharks to very young calves or badly injured whales. Up to 15% of
humpback whales in an area may have scars from orca attacks that they have
survived. That`s what I researched about previous amazing facts on whales. I
enjoyed to researching about whales. I think they are very intelligent and cool
animals in the ocean!
