fact 1
The blue whale is the largest animal that has ever
lived on Earth -- it's longer than six elephants
and weighs more than a Seismosaurus,
one of the most gigantic dinosaurs ever know.
fact 2
Most fish lay eggs. Whales like all mammals,
give birth to live young
and feed their babies milk.
fact 3
Fish have organs called gills that help them
get oxygen out of the water. Whales have lungs
and need to breathe oxygen from the air.
