The blue whale
Whales in the Museum
Blue whales are a type of baleen whale. This is a sample of the baleen from a humpback whale.
Baleen whales feed by filtering small animals called krill from the water around them. They do this by taking huge mouthfuls of water into their mouths. They then squeeze the water back and through a sieve of baleen plates, trapping the krill in their mouths.
Adult blue whales can take in about 70 000 litres of water in a single gulp, and eat up to 40 million individual krill a day!
