fish belong to the class chordata, which means they have a vertibrae.
whichever idiot said they were amphibians is wrong.
Chordata (e.g. fishes, amphibians, reptiles, birds, mammals)
look up the classification of species if you are still confusedSource(s): not being 12 years old not being an idiot

The cyprinid fish (8mm) and the whale shark (12m) are some of the smallest and largest fish in the sea.
At first, this might seem like an easy question to answer, but it is difficult to define what makes a fish a fish because there is so much diversity among animals that we consider to be fishes. There are more than 27,900 species of fishes alive today, living in marine and freshwaters, in environments as hot as 104°F/40°C and as cold as 28°F/-2°C, and ranging in length from 0.3 inches/8 mm to 39 feet/12 m. What characteristics unite such a diverse group of animals?

khahrosh - Fish are NOT amphibians.
And fish are not mammals or reptiles either! Fish are their own group.
Amphibians evolved FROM fish (and then of course reptiles evolved from amphibians, and birds and mammals evolved from reptiles).
Fish are aquatic, cold-blooded vertebrates with scales and usually two sets of paired fins and several unpaired fins. They are all members of the phylum chordata and make up the vast majority of all chordate species.

A fish is what's known as a "amphibian":
such are all creatures of the sea.
