Southern dolphins pay a rare visit, add to biologists' confusion http://apocadocs.com/s.pl?1309058165
Two dolphins that would be more at home frolicking in the warm bays of southern California or Mexico are cruising the chilly waters of Puget Sound and biologists are baffled by an apparent trend for tropical species to head north....
Victoria zoologist Anna Hall, who also skippers a boat for Prince of Whales whalewatching, said the only previously recorded sighting in local waters was in April 1953 when a longbeaked common dolphin stranded itself off Victoria.
"It's really, really unusual," she said....
Another Bryde's whale stranded and died in southern Puget Sound in January 2010. Bryde's whales usually prefer tropical or warm temperate waters.
It is a mystery why tropical species are coming north, Douglas said.
"It seems there is a significant change and it's probably temperature related, but we don't know much more than that," she said. "Maybe in a year or two we will be able to say that this was the beginning of a change."
