Moby Dick is the most famous whale who ever
lived. Herman Melville based his renowned novel on an actual sperm whale.
The real Moby Dick was not really an albino; only his forehead and hump
For all that has been written of the sperm whale, their life history is
still greatly unexplained. Their horrendously deep dives are known, not
from observation, but because of numerous instances where dead sperm whales
have been found entangled in deep-sea cables set at 3,000 plus feet. At
this depth, the water is totally black as no light penetrates from the
The dead whales, in many cases, were found with cable wrapped around their
lower jaw, indicating they were swimming with their lower jaw open while
trolling for food. It is believed that large males make these extreme
dives where they battle and consume giant squid. No person has ever seen
a struggle between a 60-70 foot whale and a giant squid which can reach
lengths of 60 feet. We know they exist from battle scars found on sperm
whale bodies and remains of giant squid found in the whales' stomachs.
The usual food of sperm whales are squid less than three feet in length
and the amount a whale consumes can be enormous. Thirty thousand beaks
have been found in a sperm whale stomach indicating they had eaten 15,000
squid as squid have upper and lower mandibles.
Ambergris is a valuable substance found in the lower intestine of a small
percentage of sperm whales and is believed to form around squid beaks.
This waxy substance, which is lighter than water and floats, was primarily
used as a perfume fixative. In whaling days, a whaler could make a fortune
from ambergris obtained from a single slaughtered sperm whale.
Spermaceti is another valuable substance found within the body of a sperm
whale. Within its head is an enormous lump of muscle and fatty tissue
weighing approximately 15 tons and filled with four tons of the clear
liquid, spermaceti. This liquid was the main reason sperm whales were
hunted as the liquid, when cooled, could be made into candles and other
items. Between 1835-1872, 292,714 whales were killed by the American whaling
fleet. The head of one sperm whale could yield 2,000 gallons of oil which
was used to illuminate 19th century homes.
The cavity containing this oil is called the spermaceti organ and accounts
for the large sperm whale head. It is believed the spermaceti organ is
involved with its deep-diving capabilities and also with the sperm whales'
echolocation facilities. Echolocation probably plays a role in its ability
to find giant squid in the dark depths of the ocean.
The sperm whale is a toothed whale -- the only one of the large whales
with teeth. Their teeth, only found in the lower jaw, are not used for
chewing, as their food is eaten whole.
The color of sperm whales varies. They can be grayish brown or black.
Their flukes are broad and triangular and deeply notched and straight
across on the margin.
Their single blowhole is located left and forward on the head. They are
the only whale with a 45° blow.
Males are larger than females and reach lengths of 60 feet or more; females
average 40 feet. Newborns weigh a ton at birth.
The life history of sperm whales is complex and not totally understood.
They are found in all the world's oceans. Migratory behavior between males
and females is different. Factory whaling of sperm whales was discontinued
in 1979, but they are still hunted from shore stations in various countries.
Their flesh is considered inedible by humans, but is used for animal food,
and their oil is used for industrial products. This is the animal with
the largest brain in the world.
