2. 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

3. 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.

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 there’s about a 1,000,000 roundworms per shovel full. Predators & Problems: pigs eat dirt, soil and roundworms. Tk

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

8. DDefinition : An animal with tentacles that have the ability to sting its prey. BBody Systems: Stomach, mouth, tentacle, no organs, cells that are organized into tissues. RReproduction: Cnidarians reproduce sexually and asexually. In jellyfish, the medusa releases sperm and egg cells into the water, where fertilization takes place. FFood: Cnidarians are carnivores, they eat meat and smaller fish. HHabitat: All cnidarians live in sea water. PPredators: Sea turtle, tunas, sharks, sword fish and some salmon. AAdaptations: 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. Cnidarians CH Box Jellyfish

9.  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

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 can’t see full images. They survive by finding mammal hosts and they start their life in freshwater. Flatworms Continued… CH

11. DDefinition – An animal with a soft body and no bones. BBody 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. RReproduction – 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. FFood – Mollusks eat bacteria and algae off of rocks and other surfaces. They also eat plants, soft leaves, fruits and vegetables. HHabitat – They burrow into the sand on the ocean floor. They can also live on land. PPredators – Mollusks have four main predators, starfish, otter, raccoons, and muskrats. AAdaptations – 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

12. DDefinition – An animal that has a jointed exoskeleton and jointed limbs. BBody Systems – Arthropods have a circulatory system, a brain and well developed organs for sight, sound and touch. RReproduction – Arthropods reproduce sexually, the female often lays fertilized eggs from which young hatch. FFood – 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. PPredators – Humankind is the main predator, and they can be kept in captivity (such as bees) for the production of their goods. AAdaptations – 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
