Striped Dolphin (Stenella coeruleoalbus)
Striped dolphins are distributed throughout the northern
part of the Pacific Ocean, up to and including the :Bering Sea.
Their biology has not been well studied. The females attain
sexual maturity at a length of about 215 cm. At the time of birth
the calf has attained almost half of the length of the mother's
body (approximately 100-110 cm).
Their behaviour has not been studied.
On the Pacific side of the island of Honshu striped dolphins
are hunted from September to January, rarely until February. It is
possible to hunt them at other times, but their flesh is most
palatable during that period.
Up to 10,000 are taken in a season. On a single day --
November 26, 1967 -- about 3,000 were taken, measuring from 184 cm
to 234 cm (females) and from 170 cm to 250 cm (males).
CHAPTER 4
CETACEA OF THE SOUTHERN HEMISPHERE
All the waters lying south of the Equator are classified as
being in the southern hemisphere; they are subdivided into Antarctic
waters proper (south of 40 0 S) and regions adjacent to the continents
of the southern hemisphere (north of 40 0 S), where whaling has been
carried on, or still is, by sea-going flotillas or from coastal
stations.
The first American whalers came to the warm zone of the
southern hemisphere in search of sperm whales from the North Atlantic
during the 18th century. Towards the end of the century whaling
began also for the more-easily-taken right whales in the temperate
