Taxon Definition
A taxon is a group of organisms that share a common ancestor and are therefore related. The taxon classification system is a way of organizing these groups of organisms. The categories of classification are: kingdom, phylum, class, order, family, genus, and species. Taxon – Definition Categories.
Taxonomic Categories
A taxonomic category is a group of organisms that share a certain characteristic, such as a common ancestor. Taxonomic categories can be divided into five levels: domain, kingdom, phylum, class, and order.
Domain is the broadest level, and includes all living things.
Each taxonomic category is more specific than the one below it. For example, a family is more specific than a class, and a genus is more specific than a species.
Taxa in Biology
- A taxon is a group of biological organisms consisting of one or more species.
- A taxon can be a rank, a taxonomic unit at any level in the system of classification, above the species level.
- Taxonomical Aids
Taxonomical aids are tools used to help identify and classify organisms. These tools can include a variety of techniques, such as using a microscope to look at the structure of an organism, using a DNA sequencer to sequence an organism’s DNA, or using a taxonomic key to determine an organism’s classification.

Domain: Eukarya
The domain Eukarya is composed of organisms that have a cell nucleus. This domain is divided into four kingdoms: Animalia, Plantae, Fungi, and Protista.
-
Kingdom: Animalia
The kingdom Animalia is composed of organisms that are multicellular and heterotrophic. They are able to move and respond to their environment. This kingdom is divided into six phyla: Porifera, Cnidaria, Platyhelminthes, Nematoda, Annelida, and Arthropoda.
-
Phylum: Chordata
The phylum Chordata is composed of organisms that have a notochord. This phylum is divided into four subphyla: Cephalochordata, Urochordata, Vertebrata, and Gnathostomata.
-
Class: Mammalia
The class Mammalia is composed of organisms that are viviparous, have hair, and produce milk. This class is divided into nine orders: Xenarthra, Pilosa, Primates, Scandentia, Dermoptera, Insectivora, Chiroptera,
Phylum:
Arthropoda, Class: Insecta
There are over a million different species of insects, which makes up over half of all the animal species on Earth. Insects are a phylum of arthropods, which are invertebrates with segmented bodies and jointed limbs. Insects are the largest and most diverse group of arthropods, and the only one that is visible to the naked eye.
They are incredibly adaptable, and can survive in a wide range of habitats, from deserts to rainforests.
Insects are a vital part of the food web, and play a crucial role in the health of ecosystems. They are prey for many other animals, and are also responsible for pollinating plants and breaking down dead organic matter. Taxon – Definition Categories.

Genus:
Lactarius
Species:
Lactarius tabidus
Binomial name:
Lactarius tabidus
Lactarius tabidus, commonly known as the bitter milkcap, is a species of fungus in the family Russulaceae. The fruit body is initially a white to creamy-white, somewhat flattened mushroom, but it soon discolors and becomes brown. The cap is up to in diameter, and has a prominent, flattened, nipple-like depression in the center. The gills are white, and initially close together, but later become more spaced out. The spore print is white. The taste of the mushroom is bitter, and it contains the toxin lactarius necator.
