Animals in phylum Arthropoda generally have these characteristics in common: (select all that apply) - chitinous exoskeleton - segmented bodies - jointed legs _____ may possibly be the longest animal in the world. They are a very diverse group of animals that includes but is far from limited to insects, crustaceans, spiders, scorpions, and centipedes. There are far more species of arthropods than species in all other phyla combined, and the number of undescribed species in the largest assemblage of arthropods, the insects, probably numbers in the tens of millions. Arthropods form the phylum Arthropoda, and include the insects, arachnids, myriapods, ... which includes such familiar animals as crabs, lobsters, crayfish, shrimp, krill and barnacles. Radial symmetry is the arrangement of similar features around a center. All arthropods have a hard exoskeleton made of chiton, a type of protein. Through seven subphyla are included in this classification, only three subphyla namely Trilobita, Chelicerata and Mandibulata are definitively arthropods. 2.

Phylum Arthropoda includes animals that have been successful in colonizing terrestrial, aquatic, and aerial habitats. 43 Phylum Arthropoda Arthropoda. They have jointed legs. Phyla a major groups of organisms. Arthropods are organisms belonging to the kingdom Animalia and the phylum Arthropoda. They are mostly marine animals. They possess the ability to survive in every habitat. The arthropods include crustaceans crustacean, primarily aquatic arthropod of the subphylum Crustacea. Class Crustacea is the largest and the most economically important group of marine arthropods. Arthropoda is a phylum of animals that includes many well-known invertebrates such as insects, crustaceans, spiders, centipedes, millipedes and scorpions. Phylum Arthropoda includes animals that have been successful in colonizing terrestrial, aquatic, and aerial habitats. Answer (1 of 5): Arthropoda is a Greek word meaning JOINT FEET. Arthropoda is the largest phylum of all living organisms and having members with characteristic exoskeleton and segmented bodies. Bilateral Symmetry ; Observe the live and preserved specimens on display in the laboratory. About 6,000 species exist today. Phylum Arthropoda includes animals that have been successful in colonizing terrestrial, aquatic, and aerial habitats. Crabs, lobsters, shrimp, barnacles and many other animals belong to the phylum arthropods. e. have no true tissues. Arachnida (/ ə ˈ r æ k n ɪ d ə /) is a class of joint-legged invertebrate animals (), in the subphylum Chelicerata.Arachnida includes orders containing spiders (the largest order), scorpions, ticks, mites, harvestmen, and solifuges.

Chelicerata, which includes spiders (Figure below), mites, and scorpions. The Arthropod body plan consists of segments, each with a pair of appendages. b. exhibit primitive segmentation. All of the organisms in the phylum Arthropoda have jointed appendages (body extensions that give them a wide range of controlled motion). This phylum includes insects like butterflies and beetles, crustaceans like crabs and lobsters, and chelicerates like spiders and scorpions. Insects are a Class in the Phylum Arthropoda.
