2. Porifera sponge Definition: A type of animal that filters the water it lives to get food Body systems: No symmetry-2 layers of cells Reproduction: mostly asexual- buds & branches grow from an adult sponge. These buds break off and grow into new sponges. A fertilized egg cell from a larva that leaves the parent sponge and travels through the ocean. Food: They filter the water for bacteria Habitat: Salty water in a coral reef predators/problems: Sea slugs Adaptions/fun facts: Even though they are alive they don’t move themselves AH

3. Flatworms flukes Definition: An animal such as a planarian that has flattened body a system with only one opening a simple nervous system Body systems: bilateral symmetry-each side of the body of one of these worms is mirror image of the other side. Reproduction: sexual-they reproduce by mating and laying eggs Asexual- they also can regenerate body parts that have been cut off Food: to eat a planarian extends a tube from it mouth the tube works like a straw sucking small particles and liquids into the animals stomach Habitat: freshwater environments predators/problems: crawfish Adaptions/fun facts: under a microscope they look cross eyed AH

4. Annelids earthworm  Definition: annelids such as the earthworm whose body is made up of connected sections or segments  Body systems: circulatory system-five enlarged tubes that act as hearts  Reproduction: sexual- every worm both male & female sex organs, after mating they both lay eggs  Food: soil-burrowing through the ground provides food for the worm  Habitat: ground/soil predators: birds, mostly robins  Adaptions: when they lay eggs they use a slimy covering to protect the egg AH

5. Arthropods butterfly  Definition: an animal that has an exoskeleton and jointed limbs  Body systems: butterflies do not have lungs  Reproduction: sexual-they have sex organs for reproducing  Food: butterflies do not eat anything really, but they drink liquids  Habitat: warm weather predators: birds, and monkeys  Adaptions: the butterfly’s wings are transparent AH

10. Annelids/Segmented worms Earthworm Definition: An animal, such as the earthworm whose body is made up of connected sections or segments. Body systems: Circulatory systems five enlarged tubes that act as hearts. Reproduction: Sexual, all round worms reproduce sexually with a female and a male. Food: Soil, the dig tunnels and eat the dirt as they go. Habitat: The ground in the soil. Predators: Birds, some types of beetles. Adaptations/Fun facts: when the eggs are laid the eggs have a slimy cover to protect them. JC

12. Echinoderans Sea urchins  Definition: An Invertebrate that has a exoskeleton and spines that are part of its skin.  Body system: Most Echinoderans have Exoskeletons the adults have Radio Symmetry.  Reproduction: Sexual, Echinoderans reproduce sexually with a male and female.  Food: Algae or bacteria they suck it up through tubes.  Predators: Starfish, Fish, Birds and Otters.  Fun facts: They tube feed and have spines, some spines have poison in them.

14. Porifera Sea Sponge  Definition: A type of animal that filters the water it lives in to get food.  Body system: They have no symmetry they are blobs with layers.  Reproduction: Mostly asexual, they have buds that break off into branches and grow into new sponges.  Food: They filter the water for food particles.  Habitat: They most live in salty water in a coral reef. JC

15. Porifera continued.  Predators: Sea slugs, they tear at them and feed on the pieces they break off.  Fun facts: Sponges do not move and do not have a brain but they are alive still. JC

19. Cnidarians Anemone  Definition/Description: An animal with tentacles that have the ability to sting their predators  Body Systems: Tentacles around the mouth and radial ( symmetry around its central axis) symmetry.  Reproduction: Both asexual and sexual.  Food: Meat. They only have a one-opening digestive system.  Habitat: Water/Sea/Lakes and Shorelines  Predators & Problems: Sea turtles, fish that eat coral, Echinoderms, and Crustaceans.  Adaptations & Facts: It has no organs in its body, and has cells that are organized into tissues. They’ve lived for over 650 years!

20. Nematodes Ascaris  Definition/Description: It is a group of slender, round worms.  Body Systems: The males are usually smaller than the females. They have a round, tube-like body.  Reproduction: Its only reproduction is sexual.  Food: Plants and bugs.  Habitat: Soil, water, humans and animals.  Predators & Problems: Fish eat nematodes, and hooks are man-made problems for them.  Adaptations & Facts: It is the only type of worm to have muscles in it. They can grow up to be 3ft long!

21. Mollusks Jellyfish  Definition/Description: An animal with a soft body and no bones.  Body Systems: They have a muscular foot that they use to burrow in the sand, and many other things.  Reproduction: They reproduce sexually. They release eggs and sperm into the water, which the eggs are fertilized.  Food: Snails have an organ called ‘radar’ and they use it to cut through hard surfaces like clam shells.  Habitat: Land or saltwater/freshwater.  Predators & Problems: Oysters, giant clams, other snails and people. People over-harvest the snails for their unique shells.  Adaptations & Facts: The giant African snail can grow up to be 6 inches long.

22. Echinoderms Sea Echinoderms Sea Urchins  Definition/Description: An invertebrate that has an internal skeleton and spines that are part of its skin.  Body Systems: They have radial symmetry and a two-opening digestive system.  Reproduction: They release sperm and eggs into the water.  Food: Bits of dead plants and animals that float down to the sea floor.  Habitat: Water and shorelines.  Predators & Problems: Crabs, sharks, eels, other fish, birds, octopi and bigger starfish.  Adaptations & Facts: The name comes from the Greek word ‘spiny skin’. When a predator or prey is near, they shoot out sticky fluids, or even toxins. They can eat prey that’s bigger than they are! A female can release one-hundred million eggs at once!
