Tagma (biology)

Index Tagma (biology)

In biology a tagma (Greek: τάγμα, plural tagmata – τάγματα) is a specialized grouping of multiple segments or metameres into a coherently functional morphological unit. [1]

Abdomen

The abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates.

Alessandro Minelli

Alessandro Minelli (born December 20, 1948 in Treviso, Italy) is an Italian biologist and a professor emeritus of Zoology in the Faculty of Mathematical, Physical and Natural Sciences of the University of Padova mainly working on evo-devo subjects.

Analogy

Analogy (from Greek ἀναλογία, analogia, "proportion", from ana- "upon, according to" + logos "ratio") is a cognitive process of transferring information or meaning from a particular subject (the analog, or source) to another (the target), or a linguistic expression corresponding to such a process.

Arachnid

Arachnids are a class (Arachnida) of joint-legged invertebrate animals (arthropods), in the subphylum Chelicerata.

Arthropod

An arthropod (from Greek ἄρθρον arthron, "joint" and πούς pous, "foot") is an invertebrate animal having an exoskeleton (external skeleton), a segmented body, and paired jointed appendages.

Cephalon (arthropod head)

The cephalon is the head section of an arthropod.

Cephalothorax

The cephalothorax, also called prosoma in some groups, is a tagma of various arthropods, comprising the head and the thorax fused together, as distinct from the abdomen behind.

Chordate

A chordate is an animal belonging to the phylum Chordata; chordates possess a notochord, a hollow dorsal nerve cord, pharyngeal slits, an endostyle, and a post-anal tail, for at least some period of their life cycle.

Copepod

Copepods (meaning "oar-feet") are a group of small crustaceans found in the sea and nearly every freshwater habitat.

Crustacean

Crustaceans (Crustacea) form a large, diverse arthropod taxon which includes such familiar animals as crabs, lobsters, crayfish, shrimp, krill, woodlice, and barnacles.

Gill

A gill is a respiratory organ found in many aquatic organisms that extracts dissolved oxygen from water and excretes carbon dioxide.

Harpacticoida

Harpacticoida is an order of copepods, in the subphylum Crustacea.

Hexapoda

The subphylum Hexapoda (from the Greek for six legs) constitutes the largest number of species of arthropods and includes the insects as well as three much smaller groups of wingless arthropods: Collembola, Protura, and Diplura (all of these were once considered insects).

Homology (biology)

In biology, homology is the existence of shared ancestry between a pair of structures, or genes, in different taxa.

Hox gene

Hox genes, a subset of homeotic genes, are a group of related genes that control the body plan of an embryo along the head-tail axis.

Metamerism (biology)

In biology, metamerism is the phenomenon of having a linear series of body segments fundamentally similar in structure, though not all such structures are entirely alike in any single life form because some of them perform special functions.

Mite

Mites are small arthropods belonging to the class Arachnida and the subclass Acari (also known as Acarina).

Morphology (biology)

Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features.

Opisthosoma

The opisthosoma is the posterior part of the body in some arthropods, behind the prosoma (cephalothorax).

Phylum

In biology, a phylum (plural: phyla) is a level of classification or taxonomic rank below Kingdom and above Class.

Segmentation (biology)

Segmentation in biology is the division of some animal and plant body plans into a series of repetitive segments.

Somite

Somites (outdated: primitive segments) are divisions of the body of an animal or embryo.

Spider

Spiders (order Araneae) are air-breathing arthropods that have eight legs and chelicerae with fangs that inject venom.

Taxon

In biology, a taxon (plural taxa; back-formation from taxonomy) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit.

Thorax

The thorax or chest (from the Greek θώραξ thorax "breastplate, cuirass, corslet" via thorax) is a part of the anatomy of humans and various other animals located between the neck and the abdomen.
