Fish have been on the Earth for over 500 million years – long before even the dinosaurs roamed the planet. There are over 25,000 species – more than all the species of amphibians, reptiles, birds and mammals combined.
A fish is an animal which lives and breathes in water. All fish are vertebrates (have a backbone) and most breathe through gills and have fins and scales.
Fish are cold-blooded, which means their internal body temperature changes as the surrounding temperature changes.
Fish have a specialized sense organ called the lateral line which works much like radar and helps them navigate in dark or murky water.
Fish have excellent senses of sight, touch, taste and many possess a good sense of smell and ‘hearing’. Fish feel pain and suffer stress just like mammals and birds.
Fish eat other fish, fish eggs, mollusks, aquatic plants, algae, zooplankton, terrestrial insects, water birds, turtles, frogs, snakes and mice
In some species the males and females have different shaped bodies or different coloring; in other species there is no visible difference.
Fish reproduce laying eggs.
