| Describe the animals in the arthropoda phylum. | invertebrates with segmented bodies, jointed legs, and an exoskeleton - grasshoppers, lobsters, insects, spiders, crabs |
| Describe the animals in the echinodermata phylum. | spiny, leathery-skinned invertebrates - starfish, sand dollars, sea urchins |
| What are invertebrates? | animals without a backbone. Most animals in this category. |
| What is bilateral symmetry? | a type of symmetry where the right and left sides match |
| What is radial symmetry? | the body radiates out in all directions from the center, like the spokes on a wheel - cnidarians - jellyfish, corals, sea anemones |
| What are tube feet? | the sucker-like structures on echinoderms used for movement and obtaining food |
| What is regeneration? | the ability to replace damaged or lost parts - Starfish |
| What is the pupa stage? | the resting stage during complete metamorphosis (cocoon stage) |
| What is a colony? | when social insects live in large groups it is called a _____ |
| Where is the thorax? | the middle section of an insect's body |
| What is a polyp? | the vase-shaped form of a cnidarian (tentacles on top - sea anemones) |
| name some mollusks | oysters, squids, octopuses |
| name some echinoderms | sand dollars, starfish, sea urchins |
| name some arthropods | insects, spiders, crabs |
| What are sponges? | simple pore-bearing animals |
| What is metamorphosis? | the changes during the life cycle (development) of an insect - butterfly |
| What is an endoskeleton? | a skeleton on the inside |
| number of legs | the way you can tell the difference between an insect and a spider |
| What are insects? | they have three body regions, legs, wings, exoskeleton |
| What are jointed appendages? | structures that grow from the body – jointed legs, claws, pincers, antennae |
| An arthropod's segmented body consisists of ____ | head, thorax, abdomen |
| What is an exoskeleton? | skeleton on the outside of body |
| What is chitin? | a hard waterproof surface, an exoskeleton |
| What is molting? | the process of shedding an exoskeleton to make room for growth |
| What is insecta? | the largest class of arthropods |
| Name some arachnids | spiders, mites, ticks, scorpions |
| Name some crustaceans | lobsters, shrimp, crabs, crayfish |
| Name some myriapods | centipedes, millipedes |
| What are insects | have three body regions, three pair of legs (6), antennae, wings |
| What are spiracles? | openings or air tubes for breathing |
| What is the tympanum? | structure under the wings for hearing |
| What are antennae used for? | detect air movement, vibration, smells |
| What are "simple eyes"? | They detect light & dark |
| What are compound eyes? | have many lenses that allow the insect to detect color & movement in all directions at once |
| What is a mandible? | the mouth part for chewing |
| maxilla | to push or suck food into the mouth |
| labium | acts as a lower lip to hold food |
| social animals | live in colonies - ex. bees |
| queen bee | bee that lays eggs |
| drone | bee that fertilizes the eggs |
| worker bee | bee that gathers honey and protects the hive |
| metamorphosis | change of body form and appearance |
| complete metamorphosis | four stages: egg, larva, pupa, adult – moths, beetles, bees, flies |
| caterpillar | a larva stage of a butterfly or moth |
| pupa | resting stage |
| cocoon | a web spun around the pupa |
| incomplete metamorphosis | three stages: egg, nymph, adult – grasshoppers, lice, crickets |
| nymph | the young stage resembles the adult stage |
| Arachnids | have two body parts, four pairs of legs (8), no antennae, poison glands, stingers, or fangs (scorpions, mites, ticks) |
| Cephalothorax | head and chest region that are fused together |
| Abdomen | stomach |
| Book lungs | a structure where oxygen and carbon dioxide are exchanged |
| Crustaceans | must molt their exoskeleton to grow, have one or two antennae, five pairs of legs (10), most live in water, can regenerate, (shrimp, crab, lobster) |
| What is a myriapod? | body is divided into many sections, an exoskeleton, jointed legs, antennae, simple eyes |
| An invertebrate that is a chilopods | centipedes |
| An invertebrate that is a diplopods | millipedes |
| Describe a centipede | has one pair of legs per body segment, a poison claw, and feeds on prey. Sometimes called the hundred-legged worm. |
| Describe a millipede | have two pair of legs per segment, feed on plants. Sometimes called the thousand-legged worm. |
| What does echinodermata | “spiny-skinned” – lives on ocean bottom – starfish, sea urchin, sea cucumber, brittle star, sand dollar |
| What is radial symmetry? | the body radiates out in all directions from the center, like the spokes on a wheel |
| What is an echinoderm's ray | arm |
| What are tube feet? | feet that act like suction cups to move about |
| What is a water vascular system? | a series of water-filled canals that moves in and out of the tube feet that allows the ecdhinodermata to move about |
| Which invertebrates can regenerate body parts? | crustaceans,sea stars, sea cucumbers, sponges |
