Researchers on an expedition 300 kilometers west of Vancouver Island stumbled upon a group of 25-30 endangered sei whales.

As the group approached, there was a lot of splashing and porpoising. It was determined that the pod of whales was attacking a juvenile humpback whale.

A raucous crowd has moved into Cowichan Bay and the volume and odour coming from them is wafting for blocks around. Locals estimate over 300 sea lions have descended on the Cowichan community and their presence is proving a huge tourist draw.

Three new humpback whales have been identified off the East Coast of Vancouver Island as that species makes a massive comeback in our waters.

A dead male grey whale that was found floating between Sidney Island and James Island on Thursday has been towed to Fisheries and Oceans Canada's Institute of Ocean Sciences in Sidney for a necropsy.
