The
purpose of this study was to determine why a Pseudorca crassidens,
commonly known as a False Killer Whale, is attracted to boats
in the waters off English Bay, Roberts Bank, and Whytecliff Park,
Vancouver, Canada. This paper reviews reports of solitary sociable
cetaceans worldwide and the information in these documents was
compared to history and behaviour of the lone Pseudorca.
This study makes known why solitary sociable cetaceans repeatedly
follow certain vessels. Similar circumstances have left other
Delphinidae (dolphin family) alone and separated from their
family groups. The extreme sociality of dolphins lead them to
become attracted to other moving objects within their family loss
area. Vessels that frequent their territory become most familiar
to them. These animals can locate boats that emit repeated noises. |
