100, and in 1954 about 30, common dolphins were killed in the Ceylon
region by means of hand-wielded harPoons 4.8 metres long, of which
the metal tips accounted for 0.45 mette. '
Their flesh -- fresh, dried, or salted used for human
food; leather is made from tnir hides.; oil is processed from their
blubber; and meal is made from their heads and bones for use as
animal food and fertilizer.
Bottle-nosed Dolphin (Tursiops truncatus aduncus)
These dolphins are distributed in the Indian Ocean from
equatorial waters to Australia, also from hew Zealand on the west
to tho coast of South America on the east, and off the coasts of
ArGentina and Brazil.
Little is known of their biology.
They are not hunted commercially. In 1954 eighteen of
them were killed near Ceylon.
Common Dlackfish (Globicephala melaena melaena)
It is believed that common blackfish make seasonal migrations
in the waters from the equatorial zone to 70 0 S. They stay .
in small groups, but occasionally they form herds of several hundreds
or even thousands. In 1955, for instance, a herd of almost
200 was stranded on the coast of Tasmania. Strandins have also
been reported from the Falkland Islands, South Africa, Australia,
and Eew Zealand, the majority of them in summer,. -
They feed on cephalopods. Their reproduction has not been
studied. They are not hunted commercially.
• Killer Whale (Orcinus orca)
In the southern hemisphere killer whales are found from
equatorial to Antarctic waters. • A group of them was observed in
Ross Sea at almost 79 0 S. The nature of their migrations has not
been studied.
As in other regions, they feed on cephalopods, shoaling fish
species, and. marine mammals. In areas where whales are hunted,
killer -hales tear out tee torue and glso pieces of.blubber from '
