| Question | Answer |
|---|---|
| What do all insects have? | a head, thorax, and abdomen |
| What is something a horseshoe crab has that a spider does not? | 5 pairs of walking legs |
| How do terrestrial arthropods breath? | through a network of branching tracheal tubes |
| What are the functions of an arthopods exoskeleton? | helps prevent the loss of body water, protects internal organs, and supports the body |
| What do most adult echinoderms show? (type of symmetry) | five part radial symmetry |
| Who possesses unbranched appendages? | uniramians |
| The water vascular system carries out three main body functions in echinoderms. What are they? | feeding, respiration, circulation, and movement |
| What are the classes of echinoderms? | sea urchins and sand dollars, brittle stars, sea cucumbers, sea stars, sea lillies, feather stars |
| Know everything about crustaceans body makeup. | 2 pairs of antennae, 2 or 3 body sections, 1 mandible (mouth part) |
| complex carb that makes up the cell walls of fungi; also found in the external skeletons of anthropods | chitin |
| structure, such as a leg or antenna, that extends from the body wall | appendage |
| one of the many branching air filled tubes that extends throughout the bodies of many terrestrial anthropods | tracheal tube |
| small opening located along the side of the body through which air enters and leaves the body of many terrestrial anthropods | spiracle |
| organ thaat has layers of respiratory tissue stacked like the pages of a book; used by some terrestrial anthropods for the exchange of gases | book lung |
| saclike organ in most terrestrial anthropods that extract wastes from the blood, adding them to feces that move through the gut | malpighian tubule |
| process in which an anthropod sheds its exoskeleton | molting |
| region of a crustacean formed by the fusion of the head with the thorax | cephalothorax |
| body part of a crustacean that lies just behind the head and houses most of the internal organs | thorax |
| posterior part of an anthropods body | abdomen |
| in crustaceans, the part of the exoskeleton that covers the cephalothorax | carapace |
| mouthpart adapted for biting and grinding food | mandibles |
| one of the first pairs of legs of decapods | cheliped |
| swimmer like appendages used by decapods for swimming | swimmerets |
| pair of mouthparts in chelicerates that contain fangs and are used to stab and paralyze prey | chelicera |
| pair of mouthparts in chelicerates that are usually modified to grab prey | pendipalp |
| organs in spiders that contain silk glands | spinneret |
| type of insect development characterized by a similar appearance throughout all stages of life | incomplete metamorphosis |
| immature form that lacks functional sex organs and other adult structures | nymph |
| type of insect development in which the larvae look and act nothing like their parents and also feed in completely different ways | complete metamorphosis |
| stage of metamorphosis in which an insect changes from a larvae into an adult | pupa |
| specific chemical messenger that affects the behavior of development of other individuals of the same species | pheremone |
| group of closely related animals of the same species that work together for the benefit of the group | society |
| group of individual insects specialized to perform particular tasks or roles | caste |
| structural support located iside the body of an animal | endoskeleton |
| system of internal tubes in echinoderms that carry out essential functions such as feeding, respiration, circulation, and movement | water vascular system |
| sievelike structure through which the water vascular system of an echinoderm opens to the outside | madreporite |
| suction cup like structure attached to radial canals of echinoderms; used to walk and to open shells | tube foot |
