Killer Whales Attack Pod of Narwhal
A group of 20 tagged killer whales traveling at fairly rapid speed is followed as they head straight toward the summer nursery grounds of a pod of narwhal and their young. The science team and film crew are stunned as they arrive to see the killer whales lunging at the beach, pinning the entire pod of narwhal in shallow water before devouring them all.

S33 E6 - 45s
A shift of power is taking place at the top of the world. The polar bear, once king of the North, needs ice to stalk its prey. Killer whales, or orca, on the other hand, are unable to hunt in an ocean locked in ice. As Arctic ice increasingly disappears, the tables have turned. Polar bears are struggling to survive while the now open ocean provides bountiful new hunting grounds for the whales.
Polar Bears Try to Catch Salmon
S33 E6 -
Polar bears need the ice to hunt and as it vanishes they can no longer reach their traditional prey. With each Arctic summer providing more water and less ice, some polar bears are forced to try their luck with seaweed, birds, and Arctic char, a type of salmon, as they migrate upstream to spawn. Their ability to find food and develop new hunting skills may prove crucial to their survival.
