irdoparasites occur mainly in the stomach, intestines, kidneys,
liver, and other organs. Little study has been given to the diseases
of sperm whales. Instances of attacks on them by killer whales
have been re7x)rted..
The highest kill before World War II -- 2,585 sperm whales
-- mas recorded only in 1938-39. rrom 1945 to 1954 the kill varied
from 1,431 to 5,485 per season; since the 1954-55 season it has
remained within the range of 3,856 to 6,974.
During the second .decade of the 20th century hunting off the
coasts of Africa took from 486 to 594 sperm whales in the best years,
but by the end of the 1920's the take had risen to 1000 or more.
From 1957 (when the take was 1,232) the number of sperm whales
killed began to rise, reaching its highest level (3,006) in 1965,
after which a tendency for it to fall became evident (only 1,211
were taken in 1968).
Sperm whales are also taken in South .America and Australia.
Data on the take are given in Appendixes 10, 11, and 14.
The weights of males measuring 11.1, 13.7, 14.3, 14.8, and
1.6.1 metres were 15.5, 33.4, 35.6, 40.1, and 4i).5 tons respectively.
A medium•sized sperm whale yields nu to five or six tons,
and a larger one up to seven or eight tons, of oil. The total oil
yield is 2O%-22Ç of the weight of the carcass.
Frozen meat up to
5, and meat-meal up to 3, of the carcasS weight can be obtained.
From the liver, which weighs up to 350 kg, vitamin A is
obtained, one gram of liver containing about 5,800 international
units.
In additien the liver contains water-soluble vitamins of '
the B group ( 1 PP (niacin), and B It has been noted
1' ' 2' 12' 0'
that the livers of sperm whales in the northern part of the Pacific
Ocean contain more vitamins of the B group than the livers of those
living in the Antarctic. •
The flesh of sir; whales is used as food for fur-bearers,
and also goes into the preciaration of meat-meal.
The average yield of products is as much as 30 of the
wei,,,:ht of the whale.
Amberris is a •I•oduc -b of the life-processes of the sperm
whale and is formed, apParently, in the small intestine, from which
it passes into th v rectum, in the distal "part of which most of the
