Organisms are first divided into Kingdoms such as Plants or Animals. After this, they are divided into phyla (the plural of phylum). An example of this is Chordata, which is the phylum that contains all living and extinct animals that have a notochord (the primitive beginnings of a spinal cord - even humans have one for a short while as the foetus develops in the womb).
taxonomic level in the Linnaean sequence that is above class but below kingdom. One, or usually more phyla are included in a kingdom. Plant 'phyla' are known as divisions. Eg Arthropoda (insects, crustaceans, spiders, millipedes etc).
(more than one = phyla) - The second largest group that scientists classify living things into. Each Kingdom (Animal, Plant, Fungi, Protist, Moneran) is split into phyla. Example: The Chordate Phylum (animals with backbones) is in the Animal Kingdom.
A group or category of those animals that share a similar basic body plan which differs essentially from the body plans of all other animals. Example: the animals of the phylum Cnidaria all possess stinging cells, radial symmetry, bodies composed of two layers of cells, and no anus, a combination not seen in other animals. Each phylum is subdivided into smaller categories (classes) which are furter subdivided.
phyla (pl.): the second biggest grouping in taxonomy. Phyla are groups of classes with shared characteristics. For example, the Chordate phylum is made up of classes of animals which have spines or notochords. The equivalent to phylum for plants is a division - for example, flowering plants are defined into the antrophyta division of the plant kingdom.
The segmentation of the animal kingdom into about 30 major groups collectively known as phyla. The members of each phylum share the same basic structure and organization. For instance, fish, birds, and human beings belong to one phylum - the Chordata - because all have spinal cords.
A group or category used in the taxonomic and/or phylogenic classification of organisms. A phylum is composed of one or more classes. In the classification of plants the category division is often used synonymously.
The second highest taxonomic classification for the kingdom Animalia (animals), between kingdom level and class level. The phylum Chordata includes all of the "higher" animals, including fish, amphibians, reptiles, birds, and mammals while Arthropoda picks up the insects, spiders, and crustaceans.
A phylum is a term in linguistics used for language classification which denotes the highest recognized level of hierarchy. Unlike a language family, the genetic relationship between members of a phylum does not have to be fully proven.
