Arthropods are found in all parts of the world in a wide variety of environments, from the deep sea to the frozen arctic regions. Classification of Phylum Arthropods: On the basis of body divisions and presence or absence of certain appendages, the phylum arthopoda is divided into seven classes. They include the classes Pycnogonida (sea spiders), Merostomata (horseshoe crabs), and Arachnida (scorpions, daddy-long-legs or harvestmen, spiders, and the mites and ticks of the order Acarina). Class 3: Crustacea 4. "animals with jointed legs".This represents approximately three-quarters of all known biological organisms, living or extinct.

These lines are represented by the extinct Trilobita and the three living- Chelicerata, Crustacea and Uniramia. This decision was based on DNA mapping and shared behavioral characteristics by some species. The below given classification is the most accepted one.

These comprise the most diverse phylum on our planet, and there are well over one million described species. Chelymorpha cribraria (Fabricius), tortoise beetle. Arthropoda is classified into five classes on the basis of body divisions, body appendages, habitat, organs of respiration and modes of excretion. Body is divided into three parts, head, thorax and abdomen - the distinguishing feature of insects: Head has one pair of antennae. Multicellular animals are sometimes known as metazoa which has been divided into two branches: Parazoa and Eumetazoa. Phylum Arthropoda . Class: Onychophora. Moulting is necessary for growth.

Arthropod Poetry - short riddles (poems) where students have to guess the associated vocab Arthropod Chart - students complete a chart outlining the characteristics of arthropod subphyla Crustacea: The body is divisible into cephalothorax (head + thorax) and abdomen. The Arthropoda (from the Greek Arthron, joint and podus, foot) are the largest group of organisms and they occur in all environments on earth. An arthropod is an invertebrate (an animal without a backbone) that has jointed legs and a segmented body. Another example of a Kingdom Animalia species is the Domestic Chicken. Phylum Eciton burchellii is in the Phylum Arthropoda because they are bilaterally symmetrical protostomes (symmetrical between one longitudinal plane of symmetry with the mouth forming first in growth) and strong, segmented bodies.

From tiny terrestrial insects to the aquatic king crab equipped with a 12 foot arm span, arthropods are evident in every habitat on Earth. o Number of extant species of class insecta: 6-10 million. The arthropods are traditionally divided into four subgroups or subphyla: trilobites (all are extinct, but the fossil record indicates that they were once the dominant subgroup), chelicerates, crustaceans, and uniramians. Fused segments - tagmata - Head, thorax, abdomen. They are bilaterally symmetrical, triploblastic, coelomate animals. Subphylum Chelicerata - horseshoe crabs, spiders, ticks, mites, and some extinct groups 3. Animal cells don't have cell partitions.
