Terms: Phylum Arthropoda – largest animal phylum, has a nervous system like the annelids, jointed appendages, has a 3-part digestive system. Consists of crayfish, scorpions, and spiders. Foregut – The digestive system portion that stores food. Midgut – The digestive system portion that makes enzymes and where digestion occurs. Hindgut – The digestive system portion that absorbs water. Tracheal System – A system of tubes that insects have. Has spiracles, tracheae, and tracheoles. Subphylum Chelicerata – No true mandibles or antennae are present in this subphylum. There are 2 body divisions and chelicerae. Class Merostomata – The horseshoe crab belongs to this class. It has 6 pairs of appendages, has pinchers, and they eat annelids. Class Arachnida – This class consists of scorpions, spiders, mites, and ticks. Scorpions – This creature has stinging and secretive features and they are carnivorous. Harvestman – An organism that has 2 body parts, also known as a daddy long leg. They do not produce silk, so they are not considered spiders. Subphylum Crustacea – The majority of these organisms are aquatic. They have 2 body parts, and the appendages are biramous. Compound eye is present. They are dioecious. Biramous – This means forked, with two branches. Class Copepdia – This serves as a class that has the most important food source for other organisms. Important portion of the food chain. Order Isopoda – Compound eye is present. They are dorsoventrally flat and have 8 segments. No carapace is present in these organisms. Order Amphipoda – Consists of mini shrimp and they are laterally compressed. Order Decapoda – Consists of lobster and crayfish. They have 10 pairs of legs and respire through gills. Compound eyes are present, and they are economically important.

Subphylum Uniramia – Organisms are primarily terrestrial. They have branched appendages, one pair of antennae, a tracheal system, mandibles, and are considered dioecious. Class Chilipoda – These have 1 pair of legs per segment and are considered to be centipedes. They can be poisonous predators. Class Diplopoda – These organisms have 2 pairs of legs per segment and are known as millipedes. Class Insecta – Organisms that have 3 body parts, a head, thorax, and abdomen. They have 3 pairs of legs, and the wings and legs are on the thorax. Pollination – About 2/3 of all flowering plants depend on insects to do this process. Complete Metamorphosis – This is when there is an egg, larvae, pupa, and adult stage. This process occurs in flies, wasps, and beetles. Incomplete Metamorphosis – Process where there is an egg, nymph, and adult stage. The organisms develop their wings over time. Gradual Metamorphosis – Process where there is an egg, immature, and adult stage. Hymenoptera – The class that is made up of insects, bees, wasps, and ants. Colony – Individual insects cannot live or exist outside of this Coleoptera – This is known as the largest group of insects, otherwise known as beetles. Hemiptera – These are known as true bugs. An example would be a stink bug. Diptera – Known as flies and mosquitoes. They have one pair of wings. Orthoptera – Known as grasshoppers, crickets, and cockroaches. Lepidoptera – Known as butterflies and moths....
