Ex: earthworms Annelids Definition: An animal such as the
earthworm whose body is made of connected sections or segments.
Body Systems: earthworms have a heart. They also have a brain.
Reproduction: All earthworms have both male and female sex organs.
After they mate they produce eggs. Food: Two sets of muscles move
through the soil. That way, soil gets to the feeding tube of the
earthworm. Habitat: They live in soil that is moist.
Predators/Problems: Birds, Snakes, Pigs, and other animals eat
Earthworms. Adaptations/Fun Facts: To get oxygen Earthworms breathe
through their skin. Tk

Echinoderms Ex: Starfish Definition: An invertebrate that has
an eternal skeleton and spines that are part of its strand. Body
Systems: They have no brain. But it does have nerves. It also has
radial symmetry. Reproduction: They reproduce sexually and
asexually. Food: The mouth of the animal is at the center of its
body. They have powerful jaws and poison glands. Habitat: They
mostly live in oceans. Predators & Problems: Crabs, octopuses
and humans. Adaptions & Fun Facts: The starfish have suction
cups.
Slide 4
Nematodes Ex: a pin worm Definition: A roundworm has a round
tube-like body. Body Systems: there digestive system has two
openings. The worms nervous system has a brain and other simple
sense organs. Food: they eat by harming other organs. Habitat: they
live in soil because it said theres about a 1,000,000 roundworms
per shovel full. Predators & Problems: pigs eat dirt, soil and
roundworms. Tk
Slide 5
Example: Flower basket Sponge Definition: Is one type of animal
that filters with water it lives in to get food. Body systems: the
beating motion of the long, whip like structures of the cells force
water through the sponge. Reproduction: it can reproduce sexually
and asexually. Food: a living sponge filters the water it lives in
to get food. Habitat: sponges live under water because it collects
crumbs at the bottom of the water. Adaptations & fun facts:
there are over 5000 species of poriferas/sponges. Tk

DDefinition : An animal with tentacles that have the ability to
sting its prey. BBody Systems: Stomach, mouth, tentacle, no organs,
cells that are organized into tissues. RReproduction: Cnidarians
reproduce sexually and asexually. In jellyfish, the medusa releases
sperm and egg cells into the water, where fertilization takes
place. FFood: Cnidarians are carnivores, they eat meat and smaller
fish. HHabitat: All cnidarians live in sea water. PPredators: Sea
turtle, tunas, sharks, sword fish and some salmon. AAdaptations:
They survive because their bodies are squishy and their tentacles
contain poison that allows them to kill or paralyze prey or
predators. A box jellyfish is the deadliest sea critter on earth.

Definition: An animal, such as a planarian, that has a flat
body, a digestive system with only one opening, and a simple
nervous system. Body Systems: Flatworms have bilateral symmetry.
Flatworms have a simpler organization. Flatworms differ from
sponges. Nerve cords extend the length of a planarians body.
Reproduction: Flatworms have reproductive systems with sex organs
and can reproduce by mating and laying eggs. Food: A flatworms
digestive system has only one opening. A planarian has at the end
of a long tube. It is used to take in food and to push out waste.
Flatworms eat sea slugs and they feed on animals. Habitat:
Flatworms live in freshwater streams, lakes and ponds. Predators:
The flatworm eating sea slug, peppermint shrimp, caribbean cleaner
shrimp. Flatworms CH Sheep Liver Fluke
Slide 10
Adaptations: Flatworms are about 1 inch long. Flatworms eyes
are on top of its body. Flatworms mouth is under its body. They
sense light and darkness but they cant see full images. They
survive by finding mammal hosts and they start their life in
freshwater. Flatworms Continued CH

DDefinition An animal with a soft body and no bones. BBody
Systems Mollusks have complex body systems, they have circulatory
systems, they have an organ called the mantle which lies between
the animal and its shell. RReproduction Mollusks reproduce
sexually. They release eggs and sperm into the water, where the
eggs are fertilized. The fertilized eggs turn into larvae. The
larvae are covered with hair like structures and move like spinning
tops. Each larvae can turn into adults. FFood Mollusks eat bacteria
and algae off of rocks and other surfaces. They also eat plants,
soft leaves, fruits and vegetables. HHabitat They burrow into the
sand on the ocean floor. They can also live on land. PPredators
Mollusks have four main predators, starfish, otter, raccoons, and
muskrats. AAdaptations Sea snails have gills that let them breathe
under water. They have hard shells that protect their bodies.
Mollusks can sting and bite, they also can be venomous, they use
their defense against their predators. Mollusks Sea Snail

DDefinition An animal that has a jointed exoskeleton and
jointed limbs. BBody Systems Arthropods have a circulatory system,
a brain and well developed organs for sight, sound and touch.
RReproduction Arthropods reproduce sexually, the female often lays
fertilized eggs from which young hatch. FFood Most arthropods eat
other animals. They use poison, pincers and/or fangs to capture
prey. They have a digestive system with 2 openings. Some crush
their food, others may pierce, suck or slice. Habitat Almost all
arthropods live on land, however crustaceans, like the lobster, can
live in water. PPredators Humankind is the main predator, and they
can be kept in captivity (such as bees) for the production of their
goods. AAdaptations Arthropods are the largest Phylum of animals.
Some arthropods are venomous, and some carry diseases. A lot of
them have many useful purposes. Arthropods CH Scorpions
