Phylum Arthropoda
CLASS CRUSTACEA |
Crustaceans
-two examples are crabs and crayfish -one or two pairs of antennae -5 or more pairs of legs -crawfish use a chileped or claw used to capture food |
|
PHYLUM ECHINODERMATA
|
Echinoderms
-5 main types-- sea stars, bottle stars, sea urchins, sand dollars, and sea cucumbers -echinoderm means "spiny skin" -move and capture prey with arms and tube feet -can regenerate broken off body parts |
|
PHYLUM ANNELIDA
|
Segmented Worms
-tube shaped bodies of all segmented worms divided into little segments -two example--earthworm and leech -on the outside of each segment are bristle-like structures called chaetae, helps them move through soil -earthworms are the simplest organisms to have a well-developed nervous system with a very simple brain |
|
Phylum Mollusca
CLASS CEPHALOPODA |
Cephalopods
-four examples--squid, octopus, cuttlefish, and nautilus -squid and octopus have well developed nervous systems, and large eyes, similar to human eyes -cephalopods have a closed circulatory system--blood moves through vessels -cephalopods swim with jet propulsion--moving water in one direction while being forced in the other |
|
Phylum Mollusca
CLASS BIVALVIA |
Bivalves
-four examples--clams, oysters, mussels, sand scallops -bivalve means two shells -bivalves are mostly filter feeders; they strain their food from the water -sessile-do not move |
|
Phylum Mollusca
CLASS GASTROPODA |
Gastropods
-two examples--snails and slugs -three main characteristics-soft bodies, mantle, and foot -gastropod means "stomach-foot" |

PHYLUM NEMATODA
|
Roundworms
-two examples--whipworm and hookworm -many are parasitic -cylindrical bodies -covered by hard oute layer called cuticle |
|
PHYLUM PORIFERA
|
Sponges
-bodies are covered in pores -sponges feed by straining food from water -sessile-attached to hard underwater surfaces |
|
PHYLUM CNIDARIA
|
Cnidarians
-three examples--pacific elk coral, pipe organ coral, and flower coral -use stinging cells to catch prey -two basic body forms--Polyp and Medusa |
|
Phylum Chordata
CLASS AMPHIBIA |
Amphibians
-three examples--spotted salamander, crocodile newt, and yosemite toad -name of class means 2 lives -all go through larvae and adult stages of life -all lay eggs in water -3 chambered heart -all have moist skin so they can breathe in oxygen from air -none have claws -all ectothermic |
|
Phylum Chordata
CLASS AVES |
Birds
-three examples--purple martin, ostritch, and mandarin duck -all lay eggs to reproduce -all have hollow bones, lungs, and a 4-chambered heart -all endothremic -all have feathers to help keep body temperature high |
|
Phylum Chordata
FISH CLASSES |
Three Groups Of Fish
-three examples--mako shark, green oray eel, and sea lamprey -three classes of fish -all members of this phylum have gills for breathing -many have scales covering their bones -all lay eggs underwater -all have fins for swimming -all ectothermic -three groups are jawless, cartilaginous, and bony |
|
Phylum Chordata
CLASS MAMMALIA |
Mammals
-three examples--vampire bat, killer whale, and duck-billed platypus -all have hair and teeth -all have lungs they use for breathing -all have mammary gland--produce milk for the mother to nurse her young -animals in this class give birth to live young -all endothermic |

Reptiles
-three examples--rattlesnake, green sea turtles, and tokay gecko -all have scales to cover their bodies -all have claws on the ends of their legs -most have a 3-chambered heart -all lay eggs on land -all ectothermic which is why you can see some members of this class warming themselves on rocks dring sunny days |
|
ENDOTHERMIC
|
can regulate their own body temperature; warm-blooded
|
|
ECTOTHERMIC
|
can't regulate their own body tempereature, body temperature matches that of enviroment; cold-blooded
