More about fish

• There are more species of fish than all the species of amphibians, reptiles, birds and mammals combined.

• 40% of all fish species inhabit fresh water, yet less than .01% of the earth's water is fresh water.

blowfish, developed their famous “inflatability” because their slow, somewhat clumsy swimming style makes them vulnerable to predators.

• In lieu of escape, puffer fish use their highly elastic stomachs and the ability to quickly ingest huge amounts of water (and even air when necessary) to turn themselves into a virtually inedible ball several times their normal size
