In only one week, the corpses of four humpback whales have been found along Canada's west coast, fueling questions of whether their deaths are connected to a recent uptick of whale and other marine animal deaths in Alaskan waters. So far scientists don't know what's causing the deaths, but some believe they could be connected to warmer than average ocean temperatures that have caused unusual and potentially poisonous algae blooms.

Of those, 18 are believed to be linked to a single event, although there is no direct cause known at this time.
