Phylum Arthropoda
Characteristics:
Symmetry bilateral
Jointed limbs, bodies are divided into sections,
exoskeleton, well-developed nervous system
Phylum Arthropoda
Class Arachnida:
 8 legs
 Examples: spiders, ticks
Drawing:
Class Insecta:
Class Crustacea:
 Gills for breathing in water
 Examples: crabs, lobster, shrimp
 3 body parts: head, thorax, abdomen
 6 legs
 Examples: butterflies, lady bugs, grasshoppers,
dragonflies, beetle

Drawing:
Phylum Echinodermata
Characteristics:
Symmetry Radial
 Live in the ocean, bodies have 5 equal segments
Phylum Mollusca
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
How they move: water vascular system and tube feet
Drawings:
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 Annelida
Characteristics:
Symmetry bilateral
Body is divided into identical divisions called
segments
Examples: earthworms, leeches
Drawings:
Benefits:

Phylum Echinodermata
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.
Drawings:
Phylum Porifera
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
Phylum Chordata Subphylum Vertebrata
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
