Parifera/Sponge Venus Flower-basket Definition: A type of animal that filters the water that it lives in to get food. Body Systems: Not symmetrical, sponges don’t have nervous, digestive, or circulatory systems, they mostly rely on constant water flow through their bodies. Reproduction: Most often sponges reproduce asexually & sexually. Buds and Branches grow from a parent sponge. These buds break off and grow into new sponges. Food: Sponges don’t eat, a current flow through their bodies gives them food, water, and oxygen. The water also helps remove waste. Habitat: Lakes, ponds, streams, found on growing rocks or sticks under water. Predators/Problems: One problem that kills sponges is that humans use sponge skeletons to make loofahs and other household items. Adaptations/Fun Facts: Sponges can be anywhere in size from 1cm. to 2m. Water flowing inside of sponges is what keeps them alive. XM

Platyhelminthes Planarian Definition: An animal such as a planarian, that has a flattened body, a digestive system with one opening, and a simple nervous system. Body Systems: Usually 30 mm. 2 nerve cords run down the length of its body. It has a mouth and the end of a long tube. Body organs made of tissues. Reproduction: Have sex organs and can reproduce by mating and laying organs. They can regenerate body parts that have been cut off. Food: Planarians have a tube on their underside where they suck food into. Habitat: They live in freshwater streams, lakes, and ponds. They stay out of light by hiding under rocks. Predators & Problems: Some fish might eat planarians. Adaptations & Fun Facts: Their habitat structure helps them survive, they stay out of light, or under something during the day. XM

Annelids Earthworm Definition: An animal, such as the earthworm , whose body is made up of connected sections, or segments. Body Systems: Five enlarged tubes act as an earthworms heart. The tubes pump blood through the major vessels of its body. Reproduction: Earthworms have both male and female sex organs, after worms mate, both partners lay eggs and produce a slimy covering that forms a cocoon protecting the eggs. Food: Food is taken through the mouth, and stored in a sac. Habitat: earthworms live in rich soil and their “waste” enriches the soil. Predators & Problems: Humans use earthworms as fishing bait. Snakes, birds, and rodents eat worms. Adaptations & Fun Facts: Earthworms can grow up to 11 feet long. They breath through their skin. XM

Arthropods Arachnids XM Definition: An animal that has a jointed exoskeleton and jointed limbs. Body Syetems: two openings, has a circulatory system, and a brain. Has well-grown organs for sight, sound and touch. Reproduction: Arthropods reproduce sexually. Females lay fertalized eggs. Food: Arachnids get their food with their fangs or pinchers. Arachnids eat mostly anything. Habitat: Almost all arachnids live on land. There are a lot of Arachnids that live on land, than Arachnids that live any other place. Predators & Problems: Very little protection to predators. If they get threatned by an animal, they have sharp body parts that eject poison. Adaptations & Fun Facts: Spiders, scorpions, ticks, and mites are Arachnids. They have 8 legs and no antena. They have 1- 8 simple eyes. Some species are eyeless. XM

Cnidarian (ex: Jellyfish) Definition/Description: An animal with tentacles that have the ability to sting its prey or predators. (bowl shaped, tiny hooks, barbs) Body Systems: Symmetry: Yes, radial symmetry. Reproduction: Both sexual and asexual. Releases sperm into water. Egg cells develop into larvae that can move into water develop into polyps. Then break off away from parents. Food: They sting their prey with poison. They're carnivores. And they eat and poop out of their mouth. Habitat: They live in the water, most of them in sea water. Predators & Problems: The animal predators are sharks. The manmade predators are boats. Adaptations & Fun facts: Their poison protects them, The word cnidarian comes from a Greek word that means ‘sting’. HS

Nematodes (Ex: hookworm) Definition/Description: An animal, with a round tube-like body, that has a digestive system with two openings. Body Systems: Two openings. One end is the mouth the other is where it poops. They have muscles. Reproduction: They are sexual. They also have sex organs that enable it to reproduce sexually. Food: They feed on the animal that they live in. Habitat: They live in other animals and sometimes humans. They can also live in soil. Predators & Problems: Predators could be people who eat undercooked meat. Adaptations & Fun facts: People can eat hookworms. HS

Mollusks (Ex: clams) Definition/Description: An animal with a soft body and no bones. (Shell, soft body and gills) Body Systems: They’re filter feeders. They have kidneys , muscles, nerve chords, intestines, and gills. Reproduction: They are sexual. They release eggs and sperm into the water, where eggs are fertilized, then they develop into a larvae then they become an adult. Food: They eat food particles. Take them in and push out water through organs called siphons. Habitat: They live in the Southern Pacific Ocean. They can also live in the Coral Reef. Predators & Problems: Predators could be the people who eat clams, lobsters and starfish. Adaptations & Fun facts: The word mollusk means soft in Latin. HS

Echinoderms (ex: starfish) Definition/Description: An invertebrate that has in internal skeleton and spines that are part of its skin. (Suction cup, tubed feet) Body Systems: They have radial symmetry. They have no brain and they have a nerve system. Reproduction: They are sexual and asexual. Their arms have sex organs. The females release millions of egg cells, and males release millions of sperm. Eggs hatch into larvae. Food: They wrap their arms around it’s prey using their suction cups. Habitat: They live in the ocean. Predators & Problems: People eat starfish. Adaptations & Fun Facts: Echinoderms means ‘spiny’ and ‘skin’ in Latin. HS
