18 GLOSSARY Abdomen: Antenna: Behavior: Carapace: Cephalotharax: Claws: Contaminate: Crayfish: Crustacean: Diet: Dominant: Female: Habitat: Identify: Length: Male: the elongated portion of the body of an orthropod located behind the thorax. It is usually segmented. a sensory organ found in pairs on heads of organisms, including insects & crustaceans. the way an animal or object reacts under certain conditions. a thick hard case or shell that covers the body, especially the back of an animal such as the crayfish or crab. fused head and thorax of many crustaceans. an appendage used for grasping in crayfish, crabs and other invertebrates, pincers. to make impure, unclean, especially by mixing impurities into it. a freshwater crustacean with large claws. an anthropod with several pairs of jointed legs, hard protective outer shell, two pairs of antennas, and eyes at the end of stalks the food an animal consumes. relating to a single animal or animal species that is greater in number, power or importance within a community or over a specific period. belonging to the sex that produces eggs or young. a natural or controlled environment in which a plant or animal lives. to recognize something and name what it is. the distance along an object from end to end. belonging to the sex that produces sperm to fertilize female eggs. 17

19 Mass: Maxilliped: Observe: Observation: Pincer: Prediction: Preference: Research: Social: Swimmerets: Telson: Walking legs: Width: Uropod: the amount of matter an object contains. specialized feeding appendages located behind the maxillae on the heads of crustaceans. to watch someone or something attentively, especially for scientific purpose. the record of observing natural phenomenon and noting developments. front claws of some crustaceans used for grasping objects. forming an opinion of what will happen based on previous knowledge or experience. opportunity to choose a course of a time that is considered more desirable than another. investigation into a subject in order to discover facts. relating to the way animals in groups behave or interact. an abdominal appendage on some crustaceans that is adapted for swimming, and in females, for carrying eggs. the last segment of an arthropod. legs used by crayfish for movement. the distance from one side or edge to the other. either of a pair of flat appendages on the last abdominal segment of a crustacean. 18
