My name is Catriona Donohoe. I am in 4th class. I have chosen whales . I read a book about whales and also found infomation in The World Book, volume 21. Fish have gills and whales have to come up to blow out of thier blowholes.
Whales look like big fish but they are mammals like horses and cats.
When whales come up to breathe they make a spout of water. A baby whale is called a calf. The mother whale gives birth under water. She pushes her calf to the surface so that it can breathe. A baby whale sucks milk from its mothers body.
