A large division of Articulata, embracing all those that have jointed legs. It includes Insects, Arachnida, Pychnogonida, and Crustacea.
This phylum includes over 80% of the world's known organisms and includes animals which live in almost every habitat on earth. Arthropods all share the following in common: body segmentation, a hard exoskeleton (external skeleton), and jointed appendages. Phylum Arthropoda includes insects, crustaceans, and spiders.
phylum of animals noted for their hard exoskeleton composed of chitin, jointed appendages and including such organisms as insects, spiders and crustaceans
a large phylum of invertebrates that include crustaceans, arachnids, insects, diplopods, and chilopods. All arthropods have a segmented body, a thick exoskeleton that is moulted from time to time and a number of jointed appendages modified in various ways to form legs, antennae, jaws or cerci
The phylum Arthropoda includes invertebrate animals such as insects, crustaceans, and spiders. The name "arthropod" means 'jointed leg', and refers to the appearance of these animals, which are also caharacterized by their segmented bodies.
jointed-foot invertebrates: arachnids; crustaceans; insects; millipedes; centipedes
A phylum consisting of invertebrate animals. In the adult form, arthropods are characterized by paired, segmented legs, an exoskeleton, and segmented bodies. Certain immature and/or parasitic forms lack some or all of these characteristics.
