The blue whale
Whales in the Museum
The blue whale is a baleen whale - it filters its food, and has no teeth. But not all whales are like this - some species have teeth they use to catch and eat fish and marine animals.
This picture shows the lower jaw of a sperm whale on display in the Museum. It is over five metres long and is covered in large peg-like teeth. Teeth like these were once carved by whalers and used to make decorative ornaments called scrimshaw.
