2. Porifera Venus- Flower- Basket- Sponge
Definition: A type of animal that filters the water it lives in to get food. Body System: Sponges have asymmetrical- they don’t have a body system. Reproduction: Most often sponges reproduce asexually, buds and branches grow from a parent sponge. These buds break off and grow into new sponges. Some sponges also reproduce sexually. They form eggs and sperm cells. A fertilized egg cell forms and its in larva then travels out of the parent sponge to a hard surface where it will grow. SM

3. Food: Sponges eat the bacteria in water
Food: Sponges eat the bacteria in water. They filter water through the openings on them through canals which specialized cells with whip like structures that removes small food particles.
Habitat: They live in shallow ocean waters and sponges attach themselves to hard surfaces and human – made structures.
Predator and Problems: Sponges predators are fish, shrimp, sea turtles, etc.
Adaptations and Fun Facts: Scientists know of about 5000 species of sponges. SM

4. Platy Helminthes/Flatworms Planarian
Definitions: An animal, such as a planarian, that has a flattened body, a digestive system with only one opening, and a simple nervous system. Body System: They have a nervous system and a digestive system also bilateral system. Reproduction: Planarians have reproductive systems with sex organs and by mating and laying eggs. They can also regenerate body parts. That have been cut off. Food: Flatworms suck through a tube for food small particles and liquids. Habitat: They live in freshwater streams, lakes, and ponds. Predators and problems: They can become a deadly disease and can live in animals. Predators are aquatic insects, dragonflies, beetles, tadpoles, small fish, and crustaceans. Adaptations and Fun Facts: They are unique for being parasites that they can be a serious diseases that can affect more then 200million people. SM

5. Cindaria Jellyfish
Definitions: An animal with tentacles that have to ability to sting its prey or predators . Body Systems: Have radial symmetry invertebrates , no organs instead they have cells that are organize into tissue. Reproduction: They can reproduce sexually and asexual. Food: Meat eater. Habitat: In the ocean and grate barrier reef. Predators and Problems: Sea turtles and sun fish. Adaptations and Fun Facts: There tentacles help them survived. They have a small stomach and a large mouth. RJ

7. Nematodes Ansaris
Definition: An animal, with a round tube like body that has a digestive system with two openings. Body systems: Bilateral symmetry , digestive system with two openings. Reproduction: They can do it a sexually. Food: Soil, dirt, and leaves. Habitat: Ground, and soil. Predators and problems: People Adaptations and fun facts: Round worms are parasites about 65,000 have bad diseases. RJ

9. Annelids Earth worm
Definition: An animal, such as the earth worms, whose body is made up of connected sections or segments. Body systems: Circulatory systems- five enlarged tubes act as the hearts. Reproduction: Sexual- every earth worm has both male and female sex organs after both worms lay eggs. Food: Eat soil though there mouth when moving though dirt. Habitat: Soil, and earth ground. Predators and problems: Humans, fish, and birds. Adaptations and fun facts: When they lay eggs they cover them in a slime to protect them. RJ

11. Mollusks Squid
Definitions: An animal with a soft body and no bones. Body Systems: Squid have a nervous system. Reproduction: Squid reproduces sexually they release eggs and sperms into the water where the eggs are fertilized. Food: Squid prey on other marine animals. Squid get their food with tentacles. Habitat: Squid live in the ocean. Predators and Problems: Some people eat squid and use squid as bait. Adaptations and Fun Facts: They are most active most intelligent mollusks. They have ten tentacles. SM

12. Echinoderms Starfish
Definitions: An invertebrates that have internal skeletons and spines sticking out from their bodies.
Body Systems: Starfish have radial symmetry a digestive systems and nervous system.
Reproduction: A starfish can reproduce sexually because a female releases millions of eggs in to water and a male releases millions of sperms and then the eggs fertilized and the egg turns in to larvae.
Food: Starfish eat meat, they have small jaws that break through shells like mollusks, clams, mussels, oysters, and more rare tiny ocean bugs and parasites.
Habitat: Starfish live only in the ocean.
Predators and Problems: Their predators are sea otters, manta rays, sharks, seagulls, etc.
Adaptations and Fun Facts: Starfish get oxygen from sea water. SM
