Yesterday we were a bit confused about some animal facts: do whales have teeth and can ducks fly?
1. Do whales have teeth?
Well, some whales have teeth and others have a baleen, which is a filter-feeder system. Don't worry, we will explain both systems in class. Meanwhile, have a look at these images.
