Arthropod Dissection Lab

Arthropod Dissection Vu- PAP BIO- 2


An arthropod is an invertebrate animal with an exoskeleton, jointed appendages, and body segments. Arthropods are members of the phylum Arthropoda which means "jointed" in Greek. These arthropods are characterized by their jointed limbs. They make up eighty percent of earth's known animals.

Arthropod Objectives

Students will learn about arthropod body parts, their digestive system, circulatory system, and other background info. They will learn this info from research and a dissection. This flyer will be over crawfish and grasshoppers.

Arthropod Respiratory System

Aquatic arthropods possess gills for respiration. However terrestrial arthropods possess trachea or book lungs for respiratory reasons. Tracheal systems are highly efficient in arthropods. Chitin linings prevent collapsing of the exoskeleton, and prevent the loss of water. Little gas exchange occurs because these creatures are so small.

Scientific Names
