The primary division of classification in the plant or animal kingdom based on common characteristics and assumed common ancestry.

A major group within a kingdom. Members of a phylum share a common structure and organization.

A major grouping of species with similar special characteristics. An example is the arthropods, a phylum that includes insects, spiders, scorpions, millipedes, crabs, and other jointed-leg animals.

Level of taxonomy below Kingdom and above Class. Birds are in the phylum Chordata. (Plural is Phyla.)

the primary taxonomic division of the animals and plants that have the same general plan and are considered to be related.

One of the major groups used in classifying animals, coming below kingdom and comprising one or more classes. Plural is phyla.

Classification level below Kingdom but higher than class. All vertebrate animals are in the phylum Chorodata. Note: In plants phyla are refered to as divisons.

a primary division of the animal kingdom.

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 group; see family

(pi., phyla) any of the broad, principal divisions of the animal kingdom

A division of plants and animals. It ranks below a kingdom and above a class. Its members are believed to have a common evolutionary ancestor. Also called subkingdom.

a major subdivision of classification in the animal kingdom

One of the large groups of organisms, just below the kingdom level.

A group in the classification system that includes many classes.

The second most general classification group of living things.

a category used in biological classification, below Kingdom level and above Class level.

Second largest group classification; smaller than kingdom, larger than class.

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).

(linguistics) a large group of languages that are historically related

(biology) the major taxonomic group of animals and plants; contains classes

a basic category of categorizing organisms within the five (or more) kingdoms

a group of animals which share the same basic body pattern, there is more information about the categories and grouping of animals on the taxonomy page

a group that scientists place animals in which share certain characteristics

a large group of organisms that shares the same general building plan

a major ranking of organisms, defined according to the most basic body-parts shared by that group

a primary taxonomic division of plants or animals which groups together organisms sharing a fundamental pattern of structural organization and presumably a common descent

a smaller group than kingdom but bigger than the next division called a class

a subdivision of a kingdom

a subgroup of a kingdom that has similar tissue and organ development

(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.

major taxonomic division of animals and plants that contains one or more classes.

' m) In the scientific system of classification (taxonomy), phylum is the division between kingdom and class.

FI-lum A major taxonomic group, just beneath kingdoms. 12

The second highest level of classification.

a taxonomic group of similar classes

A major level in the Linnaen taxonomic hierarchy, below that of Kingdom but higher than Class.

Level of scientific classification; below Kingdom and above Class

In taxonomy, a high-level category just beneath the kingdom and above the class; a group of related, similar classes.

In the taxonomy classification, the phylum is the category ranking below a kingdom and above a class.

(plural - phyla) In classification, a phylum is a group of related or similar organisms. A phylum contains one or more classes. A group of similar phyla forms a Kingdom.

A fundamental division or category of animals or plants.

In taxonomy and systematics, the highest level of classification below the kingdom. For instance, Mollusca (slugs, snails, clams, squids, etc.) constitute a phylum.

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.

an alternate name for division, the major taxonomic rank below Kingdom.

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 broadest taxonomic category within kingdoms.

See classification

A large group of supposedly monophyletic species - such as the Arthropods (spiders, insects, crustaceans and millipedes)

a taxonomic category within Kingdoms; e.g. sponges, arthropods, echinoderms within animals, phyla are divided into classes.

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 major taxonomic grouping in the animal kigdom, ranking just below kingdom and above class. In the plant kingdom, it is usually replaced by the division.

A class or group of plants. Phylum is a botanical term used by botanists to classify plants.

A major grouping in taxonomy.

The term for a group of closely related classes (pl. phyla).

a major group of animals, such as arthropods, molluscs and chordates (vertebrates)

n. A category in the hierarchy of animal classification between class and kingdom; phyla- pl.

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-largest major taxonomic classification rank, smaller than kingdom but larger than class.

In classification, a phylum is a group of related or similar organisms. A phylum contains one or more classes. A group of similar phyla (the plural of phylum) forms a Kingdom.

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.
