_____organs__________, and segmented worms also have _____systems______.

e. Worms live in ______water________________, or _______land_________________.

f. Worms have __________bilateral___________ symmetry. Their right and left hand sides are

mirror images of each other.

g. Worms have two openings. Food comes in the ______mouth____________ and waste goes

out the _____anus_______________.

h. Worms breathe (oxygen in and carbon dioxide out) through ________moist skin______________.

If their skin dries out they will die.

i. Worms reproduce sexually with ______sperm____________ and _______egg____________.

Worm are hermaphroditic which means their bodies make both sperm and egg cells.

j. Worms can ____________regenerate_________________. If they are cut into half they will re-grow

the missing body parts.

k. Many worms are ______parasites___________. This means they feed off other living things for food.

Mollusk Phylum

a. The three mollusk classes are _________gastropod________, _________bivalve_____________,

and _________cephalopod______________________.

b. All mollusks have a mantle that makes a _______shell_______, a muscular foot, soft bodies,

a mouth and anus, and ______bilateral_________ symmetry.

c. Mollusks are made up of ______cells______________, _______tissues________,

______organs____________, and ________systems___________.

d. Gastropod mollusks, like _snail, slug, sea snail, neudrabranch_ have _1_ shell found on the outside of

their body (except all slugs with no shells). Gastropods move by __crawling___________ on

land or in water using their muscular stomach foot. They protect themselves by hiding in their shells or

with chemicals that _____taste bad______________.

e. Bivalve mollusks, like _clam, oyster, scallop, mussel_ have ___2_ shells found on the outside of

their bodies. They have a hatchet foot that allows them to dig themselves into the sand. Bivalves

don’t move far except for the ____scallop__________ that moves by clapping its shells

together. All bivalves live in ______water_________________. When sand

gets in one, it coats the sand with mucus until a ____pearl_______ is made. Bivalves are

_____filter_______ feeders and pull food and water in and across their gills. They protect

themselves by hiding in their shells and burying themselves in the sand.

f. Cephalopod mollusks, like _squid, octopus, nautilus, cuttlefish_ have ___1__ shell found on the inside

of their bodies except the octopus with no shell and nautilus with a shell on the outside. They have a

head foot that is broken up into ___tentacles_______________ that they use to move around and

capture food. Cephalopods can use _____jet propulsion__________ to move away from

predators very quickly. An octopus is able to change its body size, shape, and color to blend into its

surroundings. Many cephalopods also have ink to cloud up the water and let them escape. All

cephalopods live in ______water___________.

g. Mollusks reproduce sexually with ___sperm_________ and ______egg____________.

Mollusks are hermaphroditic which means their bodies make both sperm and egg cells.

Arthropod Phylum

a. The four arthropod classes are _____myriapod_______, _______crustacean____________,

________insect______________, and _______arachnid______________.

b. All arthropods have an ____exoskeleton___________ covering their body that they molt when it

gets too small for them, jointed appendages, segmented bodies, a mouth and anus, and __bilateral___

symmetry. Arthropods were the first to have separate ____genders______ and reproduce

sexually with sperm and egg. They also have a mandible (jaw) for chewing.

__3__ body segments. Most insects have wings and can fly, and many have claws or stingers.

All insects go through either complete metamorphosis or incomplete (gradual) metamorphosis. The

stages of complete metamorphosis are egg, ___larva____, ______pupa_____, and adult. The

animal goes through a complete change while in the cocoon. The stages of incomplete metamorphosis

are egg, ____nymph____, and adult. The animal gradually, or slowly gets larger and larger as it

molts. During the last molt, it grows wings, changes body color, and its sexual organs begin to work.

Echinoderm Phylum

a. An example of an Echinoderm is a __starfish, sand dollar, sea urchin, feather duster, sea cucumber_.

b. All echinoderms have __spiny_________ skin, a five part body, _____tube_______ feet,

a water vascular system to breathe and move with, and ____radial________ symmetry. They also

have a mouth and anus, and can ______regenerate_____ lost body parts. This allows them to

grow back what is missing or cut off.

c. Echinoderms are made up of _______cells_____________, ________tissues_____________,

_____organs____________, and _______systems____________.

d. Most Echinoderms use their ____tube feet________ to capture food and put it in their mouths.

Starfish eat by spitting their ____stomachs_____ out their mouths and digesting the mollusk in its
