Invertebrate Phylums/classes And Vertebrate Classes.

Front 1

Phylum Arthropoda
CLASS CRUSTACEA

Back 1

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

Front 2

PHYLUM ECHINODERMATA

Back 2

Echinoderms
-5 main types-- sea stars, bottle stars, sea urchins, sand dollars, and sea cucumbers
-echinoderm means "spiny skin"

Front 3

PHYLUM ANNELIDA

Back 3

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

Front 4

Phylum Mollusca
CLASS CEPHALOPODA

Back 4

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

Front 5

Phylum Mollusca
CLASS BIVALVIA

Back 5

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

Front 6
