We really enjoyed watching lesson 2, these are the main facts we gathered.
Fish have been around for 500 million years.
The fish is the first animal to have a backbone (vertebrae)
You can tell how old a fish is by counting the rings on its stomach
They breathe through their gills instead of their mouths
They are dying 5 times faster than animals on land
Our oceans are around 3% fresh water, because of that there is not much habitat for the fish because most of the fish are fresh water.
