Grasshopper Lab
Comparative Structure and Functions:
Arthropods are the largest phylum in the animal kingdom. Approximately 84% of animals are in this phylum. Members of this phylum have exoskeletons, a protective external skeleton made of chitin. Organisms in this phylum have book lungs, spiracles, or gills. Interestingly, arthropods have open circulatory system despite their high degree of complexity. This complexity can be seen in the antennae and complex eyes of the arthropods' nervous system. All of these advanced features have helped arthropods become one of the most successful phyla in the domain Eukarya.
Taxonomy:
Members of the phylum Arthropoda, known as arthropods, are organisms with segmented bodies, tough exoskeletons, and jointed
appendages. This phylum includes spiders, butterflies, shrimp, caterpillars,and lobsters, as well as many other creatures. A major subphylum of Arthropoda is Crustacea. Crustaceans typically have two pairs of antennae, two or three body sections, and chewing mouthparts called mandibles. Examples of organisms in this phylum are lobsters, crayfish, and crabs. Another major subphylum of Arthropoda is Chelicerata. These organisms include spiders, horseshoe crabs, ticks, mites, and scorpions. All of these organisms have mouthparts called chelicerae and two body sections, and nearly all have four pairs of walking legs. Insects and their relatives are in the subphylum Uniramia. These organisms have jaws, one pair of antennae, and unbranched appendages. Examples of insects are centipedes, millipedes, flies, bees, and
Ecology:
Grasshoppers lay their eggs in late summer and over winter they incubate in the soil. The grasshoppers prefer warm weather because it helps with their survival. Sometimes a bacterial disease is contracted when the weather is warm and humid this cause the grasshopper to climb to a high point and die. Grasshoppers eat leaves and only leaves. They are strict herbivores.
