Are you one of those intrigued by the question, “Is a fish an animal?” If so, you’re in the right place. This article will delve into the world of fishes and explore their classification in the animal kingdom.
The Basics: Understanding Animal Classification
Before we tackle the main question, let’s break down the basics of animal classification. The science of classifying living things is called taxonomy. It helps us understand how different creatures are related by grouping them based on shared characteristics.
Where Do Fishes Fit In?
So, where do fishes fit into this classification? Fishes belong in the animal kingdom, and they are considered vertebrates. Let’s dive into the reasons why.
The Animal Kingdom and Fishes
Biologists classify fishes as animals because they meet all the criteria for the animal kingdom. They are multicellular, eukaryotic organisms, which means their cells have a nucleus enclosed within membranes.

Moreover, fishes are heterotrophs, meaning they obtain nutrients by consuming other organisms. They reproduce sexually, have sensory organs, and exhibit complex behaviors, all of which are characteristics of animals.
Vertebrates: Fishes Make the List
Vertebrates are a subgroup of animals that have a backbone or spinal column. Fishes are included in this list because they have a bony or cartilaginous skeleton that supports their body and allows for movement.
Conclusion: Yes, a Fish is an Animal!
So, to answer the question, “Is a fish an animal?” – the answer is a resounding yes! Fishes are not only animals but are also classified as vertebrates. They share many common characteristics with other animals, including complex behaviors, the ability to reproduce sexually, and the presence of a backbone.
