What types of whales and dolphins are susceptible?
Species that aren’t used to a lot of ice, such as grey whales and many dolphins, might have more difficulty getting out, Murison said. “They just don’t have the ability to find those ice leads [channels of open water] as easily as animals that normally are in ice conditions, like bowheads or narwhals or belugas.” Some species can’t swim that far underwater before they need to come up for air, she added. However, even species that are accustomed to the ice can sometimes become trapped.
