Porifera Venus- Flower- Basket- SpongeDefinition: 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.

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.

Platy Helminthes/Flatworms PlanarianDefinitions: 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.

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.

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. S

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.
