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.
Brachiopods, phylum Brachiopoda, are a group of lophotrochozoan animals that have hard "valves" (shells) on the upper and lower surfaces, unlike the left and right arrangement in bivalve molluscs.
The subphylum Chelicerata (New Latin, from French chélicère, from Greek khēlē "claw, chela" and kéras "horn") constitutes one of the major subdivisions of the phylum Arthropoda.
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.
Craniata (formerly Craniforma) is a class of Brachiopod originating in the Cambrian period and still extant today.
Crustaceans (Crustacea) form a large, diverse arthropod taxon which includes such familiar animals as crabs, lobsters, crayfish, shrimp, krill, woodlice, and barnacles.
A fungus (plural: fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms.
Gnathostomata are the jawed vertebrates.
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).
A hierarchy (from the Greek hierarchia, "rule of a high priest", from hierarkhes, "leader of sacred rites") is an arrangement of items (objects, names, values, categories, etc.) in which the items are represented as being "above", "below", or "at the same level as" one another A hierarchy can link entities either directly or indirectly, and either vertically or diagonally.
The International Code of Zoological Nomenclature (ICZN) is a widely accepted convention in zoology that rules the formal scientific naming of organisms treated as animals.
The lancelets — also known as amphioxi (singular, amphioxus) consist of about 32 species of fish-like marine chordates in the order Amphioxiformes.
Linguliformea is a subphylum of inarticulate brachiopods.
Mycetozoa is a grouping of slime molds.
Myriapoda is a subphylum of arthropods containing millipedes, centipedes, and others.
In biology, a phylum (plural: phyla) is a level of classification or taxonomic rank below Kingdom and above Class.
Plant taxonomy is the science that finds, identifies, describes, classifies, and names plants.
Rhynchonelliformea is the name now given to the articulate brachiopods, Class Articulata, revised as a subphylum.
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in a taxonomic hierarchy.
Trilobites (meaning "three lobes") are a fossil group of extinct marine arachnomorph arthropods that form the class Trilobita.
A tunicate is a marine invertebrate animal, a member of the subphylum Tunicata, which is part of the Chordata, a phylum which includes all animals with dorsal nerve cords and notochords.
Vertebrates comprise all species of animals within the subphylum Vertebrata (chordates with backbones).
