What is the classification for fish?
by
Fishes are typically divided into three groups: superclass Agnatha (jawless fishes), class Chondrichthyes (cartilaginous fishes), and superclass Osteichthyes (bony fishes). The latter two groups are included within the infraphylum Gnathostomata, a category containing all jawed vertebrates.
Fishes are a group of animals that are completely aquatic vertebrates that have gills, scales, swim bladders to float, most produce eggs, and are ectothermic.
Is a fish an animal or amphibian?
Amphibians are vertebrates (animals with backbones) which are able, when adult, to live both in water and on land. Unlike fish, they can breathe atmospheric oxygen through lungs, and they differ from reptiles in that they have soft, moist, usually scale-less skin, and have to breed in water.
Is a fish a reptile?
A fish is an animal that lives only in the water, whereas a reptile lives in both land and water. A fish is an aquatic vertebrate that is cold blooded or ectothermic. The reptile is also a cold blooded animal that is covered by scutes or scales. Fish also have scales, although they are absent in cartilaginous fish.

Is a snail a reptile?
Answer and Explanation: Snails are neither reptiles nor amphibians, they are gastropods. There is a significant evolutionary distance between snails, reptiles and amphibians. This is because snails are not even in the same phylum as the latter two as they are in the molluscan phylum alongside squids.
