Many whales head to Antarctic waters during the Antarctic summer because the sea is full of their favourite food: krill. A humpback whale eats about one ton of krill each day. They fatten up and head to warmer waters during other seasons for breeding purposes.
If the captain spots a whale, he stops the ship and positions it for good viewing. We also see whales from Zodiak cruises.
