What are the classes of arthropod?
- Arachnid. the Class of Arthropods that includes spiders, mites, ticks, scorpions, pseudoscorpions and harvestmen.
- Chilopoda. the Chilopoda are a group of predatory arthropods more commonly known as centipedes.
- Non-insect hexapods.
How many types of arthropods are there?
Diversity. Estimates of the number of arthropod species vary between 1,170,000 and 5 to 10 million and account for over 80 percent of all known living animal species.
What are the 4 types of arthropods?
Arthropods are divided into four major groups:
- myriapods (including centipedes and millipedes);
- arachnids (including spiders, mites and scorpions);
- crustaceans (including slaters, prawn and crabs).

Which arthropods have 2 pairs of antennae?
Crustaceans have two pair of antennae. Another set of anterior appendages are modified as mandibles, which function in grasping, biting, and chewing food. Male crayfish also use one pair of legs as a copulatory organ. All crustaceans share a common type of larva called a nauplius larva.
What is arthropod group?
arthropod, (phylum Arthropoda), any member of the phylum Arthropoda, the largest phylum in the animal kingdom, which includes such familiar forms as lobsters, crabs, spiders, mites, insects, centipedes, and millipedes. About 84 percent of all known species of animals are members of this phylum.
What are the 7 classes of arthropods?
Phylum Arthropoda is Classified in to 7 classes.
- Onychophora (claw bearing) e.g. Peripatus.
- Crustacea (Crusta – shell) e.g. Prawn, crab, wood louse.
- Arachnida (Arachne – spider) e.g. Scorpion, spider, tick, mite.
- Chilopoda (Chilo – lip; poda – appendage) e.g. Centipedes.

What are the 3 main body parts that all arthropods have?
Arthropod segments have also fused together into functional units called tagma. This process of segment fusion, or tagmosis, usually results in an arthropod body that consists of three major sections, a head, thorax, and abdomen. Sometimes the head and thorax are fused together into a cephalothorax.
Which arthropods have 4 pairs of legs?
Arachnids. The arachnids, which include spiders, mites, ticks, scorpions, and horseshoe crabs, have only four pairs of walking legs and no compound eyes. Their bodies have two main regions. Most live on land and feed on insects and other small animals.
