Phylum Arthropoda
Characteristics: Symmetry bilateral Class Arachnida: Jointed limbs, bodies are divided into sections, exoskeleton, well‐developed nervous system  8 legs  Examples: spiders, ticks Drawing: Class Insecta:  3 body parts: head, thorax, abdomen  6 legs  Examples: butterflies, lady bugs, grasshoppers, dragonflies, beetle Class Crustacea:  Gills for breathing in water  Examples: crabs, lobster, shrimp Drawing: Drawing: Phylum Echinodermata
Phylum Mollusca
Characteristics: Symmetry Radial Characteristics: Symmetry bilateral Muscular foot used to move, secretes mucus to help with movement, visceral mass contains organs, mantle covers visceral mass, shell secreted by mantle protects body Examples: snails, octopus, slug, clam Classes: How they move: water vascular system and tube feet Bivalves – clams, oysters Gastropods – snails Cephalopods – octopi, squid Drawings:  Live in the ocean, bodies have 5 equal segments How they eat: sea stars push their stomach outside of themselves into a clam for example, and dissolve the prey with their digestive juices. Examples: sand dollar, sea star, sea urchin Phylum Echinodermata
Phylum Annelida
Characteristics: Symmetry bilateral Body is divided into identical divisions called segments Drawings: Examples: earthworms, leeches Drawings: Benefits: 
Earthworms helpful because they decompose dead matter and make tunnels in soil.  Leeches helpful for medical use because they keep blood from clotting and reduce swelling. Phylum
Porifera
Phylum Chordata Subphylum Vertebrata
Characteristics: Symmetry asymmetrical  multicellular, few tissues, no organs  Cells and tissues surround a water filled space but there is no true body cavity.  All are sessile, (live attached to something as an adult).  Has no nervous system.  Lives in aquatic environments, mostly marine.  All are filter feeders  Often have a skeleton of spicules Class Amphibia: Amphibians  Examples: frogs, toads, salamanders Class Reptilia: reptiles  Examples: turtles, snakes, lizards Examples: Class Aves: birds Barrel sponge, branching tube sponge  Examples: eagle, blue jay, flamingo, penguin Drawings: Class Mammalia: mammals  Examples: lion, humans, mouse, platypus Phylum Chordata Subphylum Vertebrata
Characteristics: Symmetry bilateral  Subphylum vertebrata have a backbone to support body  Nerve cord surrounded by vertebrae  Well‐developed brain  Skeletons made of bones or cartilage Phylum Cnidarian
Characteristics: Tentacles, stinging cells (nematocysts) Two body shapes:  Polyp  Symmetry: Radial  Example: Sea anemone Class Chondrichthyes: Cartilaginous Fish  Drawing:  Skeletons of cartilage  Examples: sharks, rays Class Osteichthyes: Bony Fish  Skeletons of bone  Examples: trout, bass, puffer fish Class Agnatha: Jawless Fish  Medusa  Symmetry: Radial  Example: jelly fish  Skeletons of cartilage  Examples: hagfish, lamprey  Drawing: Name ____________________________________________ Date ____________________ Block ____________________ The Animal
