Fish have been around longer than we have – since 450 million years ago. In fact, they were here before dinosaurs.


They come in huge variety – over 25,000 identified species. There are more species of fish than of amphibians, reptiles, birds and mammals combined. Scientists still think they may yet identify 15,000 more species.


Even though 60% of fish species live in the sea, 99.99% of the earth’s water is seawater, this means that 40% of all fish species live in less than .01% of the earth’s water.
