Rare Dolphin Sighting Reported in Northwest Vancouver Island
MERS says two sightings this month involved the same juvenile dolphin, a rare species that usually lives farther south.
On Wednesday, the Marine Education and Research Society reported rare sightings of Long-beaked common dolphins near North Island, a species typically found in warmer waters.
Marine mammal researcher John Ford suggests warmer ocean temperatures may explain these unusual visits, noting that sightings in 2002 and 2003 coincided with shifts in ocean conditions.
A juvenile was identified in Esperanza Inlet, while Seasmoke Whale Watching captured images of a different individual in Knight Inlet on July 4, with another documented off Malcolm Island.
While Pacific white-sided dolphins are common in British Columbia, Long-beaked common dolphins are rarely documented this far north, as the species generally prefers tropical or subtropical climates.
These Long-beaked dolphins can reach 8.5 feet, weigh between 160 to 500 pounds, and live in social groups of about 100 to 500.
