CNIDARIANS EXAMPLE: JELLYFISH Definition- An animal with tentacles to sting prey or predators Body systems- Cnidarians halve radial symmetry Reproduction- Cnidarians reproduce asexually, and sexually. Cnidarians hatch from larvae Food- Cnidarians eat meat, Cnidarians sting their prey with tentacles Habitat- Cnidarians live in freshwater (hydras), and saltwater Predators- Turtles eat Cnidarians Adaptations- Cnidarians have special tissues that digest food sc

NEMATODES/ROUNDWORMS EXAMPLE: HOOK WORM Definition- An animal with a round tube like body with a digestive system with two openings Body systems- Nematodes have bilateral symmetry, nematodes also have no circulatory system Reproduction- Nematodes reproduce sexually Food- Food goes in a hole at the front end of the nematode and goes out the back end of the nematode Habitat- Nematodes live in dirt, soil, water, and mud Predators- Insects, mites, and birds eat nematodes Adaptations- Nematodes survive by getting eaten and mature inside a human sc

MOLLUSKS EXAMPLE: OCTOPUS Definition- An animal with a soft body and no bones Body Systems- Mollusks have complete body systems, and a circulatory system Reproduction- Mollusks reproduce sexually, they release eggs into the water, and sperm into the water to fertilize into larvae Food- Mollusks eat bacteria and algae off of rocks, they also eat plants, leaves, and fruits Habitat- Mollusks live in saltwater, and freshwater, they have a muscular foot to burrow into the sand Predators- Mollusks have four main predators, Starfish, Otters, Raccoons, and muskrats Adaptations- Mollusks can have shells that grow inside the animal sc

ARTHROPODS EXAMPLE: SCORPION Definition- An animal with an exoskeleton and jointed limbs Body Systems- Scorpions have a hard exoskeleton and, a jointed exoskeleton, it also has a circulatory system Reproduction- Arthropods reproduce sexually females lay eggs Food- Arthropods eat insects Habitat- Arthropods such as scorpions live in the desert, Some such as octopus live in the ocean Predators- Arthropods eat each other, Birds, reptiles, and, fish eat arthropods Adaptations-Arthropods have jointed legs sc

PORIFERA EXAMPLE: FLOWER-BASKET SPONGE Definition- a type of animal that filters the water it lives in for food. Body system- a sponge has a simple body system, it only has 1 opening, a sponge has only 2 layers of cells. Reproduction- asexual, buds & branches grow from a parent sponge. food- little particles such as plankton,& plants. Habitat- sponges live in shallow ocean waters where they attach themselves to hard under water surfaces such as rocks, ocean floor, & other animals. Predators- NONE FUN FACTS- biologists 200 years ago thought sponges were plants.

PLATYHELMINTHES EXAMPLE: PLANARIAN Definition- an animal such as a planarian, that has a flattened body, a digestive system with only 1 opening, and a simple nervous system. Body system- the planarian has a simple nervous system, & it also has a digestive system with 1 opening, it also has sense organs in its head. Reproduction- sexual, they mate & make eggs. Food- it eats small animals with its small muscular mouths. Habitat- during daylight can be found under rocks, in the mud at the bottom of their freshwater environments. Predators- angle fish, fat heads, gumbusia, orange throught darters, red belly dace, sand shiners, central stoneroller, gold fish, guppies and a lot more. Fun facts- if you cut a planarian in 2 the place where the head was will grow a tail & the place where the tail was will grow a head. T.b

ANNELIDS EXAMPLE: EARTH WORM Definition- an animal such as a earthworm, whose body is made up of sediment over millions of years. Body system- complex body system, it has 5 hearts. Reproduction- sexual, after worms mate, they both lay eggs and cover with a slimy covering as a cocoon. Food- they eat their own castings, they have2 digestive ends. Habitat- moist soil, under logs, they usually come out of the soil after a heavy rain. Predators- fish, hedgehogs, moles, & birds. Fun facts- to get oxygen, earth worms “breath” through their thin, moist skin. T.b.

ECHINODERMS EXAMPLE: STARFISH Definition- an invertebrate that has a internal skeleton and spines that are part of its skin. Body system- radial symmetry, no brain, it has nerves that enables it to move & feed. Reproduction- sexual, each arm of a starfish has sex organs, females release millions of egg cells & males release millions of sperm cells. Food- starfish use their tube feet to eat, they eat mussel. Habitat- at the bottom of shallow waters hard surfaces such as rocks, ocean floor, etc. Predators- crabs, & sharks. Fun fact- if you cut off a starfish’s arm it will grow back.
