Arthropods By:Chipper Brockman, Andy Hwang, Di'en Jenkins, and Maddie Wade Arachnids A class of jointed-leg invertebrate animals in the subphylum Chelicerata.
All arachnids have 8 legs Drill What is an Arthropod? Arthropods are insects, crabs, centipedes, or spiders that have a segmented body, a tough exoskeleton, and appendages.
Vocab Appendages- structures such as a leg, or antenna,that extends from the body of the wall Chelicerates-special mouthparts called checlirae in two body sections used to stab and paralyze prey
Vocab cont. Chitin- complex carbohydrate that makes up the cell walls of fungi; also found in the external skeleton in arthropods Crustaceans-primarily aquatic that includes organisms such as crabs,
shrimp, lobster, crayfish, barnacles; range in size from small terrestrial pill bugs to spider crabs; typically have two pairs of branched antenna, two or three body sections, and mouthparts called mandibles Vocab cont.
Exoskeleton- external skeleton; tough external covering that protects and supports the body of many invertebrates Molting- process in which an Arthropod sheds its exoskeleton and manufactures a larger one to take its place
Vocab cont. Spiracles- small opening located along the side of the body through which air enters and leaves the body of many terrestrial Arthropods Uniramians- Centipedes, millipedes, and insects; have jaw, one pair of antenna, and unbranched appendages
Arthropods are segmented animals They also have appendages, which are jointed extensions from the body Exoskeleton is made out of three layers Have compound eyes (eyes composed of many light detectors and they each have their own lens)
3 Major Groups Crustacea: Crustacea includes shrimps, lobsters, crabs, crayfish, barnacles, isopods, and copepods. Members of this subphylum, known as crustaceans, have branched antennae and a pair of chewing mouthparts called mandibles.
Chelicerata: Chelicerata includes spiders, scorpions, mites, ticks, sea spiders, and horseshoe crabs. This group is distinguished from other groups by the absence of antennae and the presence of pincerlike mouthparts called chelicerae.
Uniramia: Uniramia includes centipedes, millipedes, and insects. Members from this group have their appendages unbranched. They are the only group to have evolved on land.

Arthropods use gills to breathe Use teeth to grind down food to eat The abdomen and cephalothorax are the two main sections of the arthropods Activity
