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.

Puffer fish• Biologists think puffer fish, also known as

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
