Fish have backbones and like all animals with backbones the phylum is chordata. There are further subclassifications in chordata; those with complete skulls are in the craniata subgroup.
The opposite of arthropods would be non-arthropods or invertebrates that do not belong to the phylum Arthropoda.
Actually, the classification of animals goes from broad to specific, starting with kingdom and descending down to species. The hierarchy is: kingdom, phylum, class, order, family, genus, and species. So, animals with a spine would be classified in the kingdom Animalia, phylum Chordata, class Mammalia (for mammals), and so on, down to the specific species.
Classifying all animals that swim in the same phylum is overly broad as swimming is a behavior rather than a specific shared evolutionary trait. Animals that swim can belong to different phyla based on their anatomical and genetic characteristics. Grouping them solely based on swimming behavior would lead to an inaccurate and misleading classification system.
Members of the same species would show the greatest similarity in terms of kingdom, phylum, genus, and species because they belong to the same biological classification group at all these levels.
A beaver would belong to the chordata phylum, same as you and me.

phylum chordata... :)
Butterflies belong in the Phylum Arthropoda, Class Insecta, etc., whereas polar bears belong in Phylum Chordata, Class Mammalia. This means that butterflies, though animals, are not vertebrates nor are they mammals: they are invertebrates and thus insects.
Bacteria without a cell wall would belong to the phylum Tenericutes. Tenericutes are a group of bacteria that have a unique cell membrane but lack a cell wall.
The opposite of arthropods would be non-arthropods or invertebrates that do not belong to the phylum Arthropoda.
Animals in the same class share more specific similarities than those in the same phylum, as class is a more refined classification that groups organisms with closer evolutionary relationships. For example, within the phylum Chordata, mammals (a class) have more in common with each other, such as characteristics like warm-bloodedness and mammary glands, than they would with reptiles or birds, which are also in Chordata but belong to different classes. Thus, comparing two animals in the same class is typically more relevant for understanding their similarities than comparing two animals in the same phylum.
No, an octopus would be an example of a mollusk (not a cnidarian).
Phylum Athropoda, ( The Arthropods) as they contain the insects of which there are 800 000 species and the insects are the most abundant animals on earth.
Most people would consider fish in the Animalia kingdom ( animal kingdom ), Fish, mammals, insects, animals of course would all belong to the Animalia kingdom. Unlike us we belong to god. But if you are Muslim or Islam or even Jewish and Sikh you would know what kingdom you belong to. -Top Contributor Hillary
Organisms belonging to the same family share the same order, class, phylum, and kingdom. For example, if two organisms are in the same family Felidae (cats), then they would also belong to the order Carnivora, class Mammalia, phylum Chordata, and kingdom Animalia.
There is no longer any difference in the classification system of plants and animals. Before, it was that you would use the term division for classifying plants instead of phylum,used to classify animals. Now, phylum can be used to classify plants and animals.
