Porifera/SpongeVenus Flower-basket Sponge
Definition- A type of animal that filters the water it lives in to get food.Body systems- There is no symmetryReproduction- Sponges reproduce asexually and sexually. Buds and branches grow from the parent sponges. They break off and grow into sponges. They can also mate.Food- Cells that remove small food particles from water.Habitat- Fresh water, sponges often grow on or near coral reefs.Predators- FishAdaptations and fun facts- Over 5,000 species of sponges

Cnidarian ex. Sea nettles Definition/ description- an animal with tentacles that
have the ability to sting Body systems- Symmetry- radial symmetryNervous- nerve netRespiratory- they do not have oneCirculatory- they lack one and they do not need one Reproduction- they reproduce both ways by releasing a
sperm and egg sells into the water and fertilization starts They sting them with there tentacles then bring them
close to there mouth They have one opening there mouth They live in the aquatic environment Food- any type of other fish, eat small things, The food they eat digest then come back up to there
mouth Fun facts- jelly fish can have up to 800 tentacles Adaptations- being able to live in the water There tentacles to be able to swim in the water A problem that they have is that the oxygen that the get
could be toxic

Roundworms ex. Heart worms Definition -An animal with a round tubelike body
that has a digestive system with two openings Body systems-Digestive- a roundworm has a definite
digestive system that runs the length of their bodies. Nervous- a roundworm has two nerve cords that
transmit impulse in the roundworm Circulation- a roundworm has no heart or formal
blood vessels Respiration- a roundworm has no formal respiratory
system Reproduction- a roundworm reproduces sexually.
The female has an ovary, holds eggs in an oviduct and then passes them to the uterus, were they are fertilized. The male has a sperm cells are made in the testis and stored in the deferens. When it is time to reproduce the sperm cells pass through the spicule. Over 200,000 eggs can be disposed at once they are fertilized.
Fun fact-In one scoop of soil there is about 1 million roundworms.

Heart Worms
Platyhelminthes/Flatwormsplanarians• Definition- An animal, such as a planarian, that
has a flattened body, a digestive system with only one opening and a simple nervous system.
• Body systems- Simple nervous system, one opening for digestive system. Bilateral
symmetry.• Reproduction- Sexual reproduction.• Food- Human or animal organs and insides.
Have one opening to get food• Habitat- Fresh water, streams, lakes, ponds,
dark areas on land.• Predators- Adedes Albopictus and Culex
Quinquefasciatus.• Adaptations- During the day Platyhelminthes
stay under rocks, and mud.

Echinoderm ex. Sea cucumber • Definition- An invertebrate that has an
internal skeleton and spines that are part of its skin.
• Body systems- they get oxygen from the water there nervous system has them enable to move or feed. Adults have radial symmetry.
• Reproduction most sea cucumbers reproduce by releasing sperm and ova into the ocean water.
• Food they have Struthers that peel food apart. They get oxygen from sea water.
• Habitat only in the ocean• Predators they’re food sources to animals.• Adaptation exoskeleton the adaptation enable
to get food and defend themselves. Many echinoderms have been powerful stays hidden under their spines and poison glands.

Sea Cucumbers
Mollusks ex. Snail • Definition – a animal with a soft bod and no
bones• Nervous- a snails nervous centers that each
control or interpret sensations for specific parts of the body
• Body symmetry- bilateral• Digestive- a steady back and forth movement of
the digestive juices between stomach and intestines enhances the process of adsorption of the food. The movement of the digestive juices is caused by the muscles of the intestinal gland and ciliate.
• Respiratory- gastropods breath through a single gill, supplied with oxygen by a current of water through the mantle cavity.
• Habitat- ocean, land• Preorders- Echinoderms• Adaptations- their soft shell •

Annelids/Segmented wormsEarthworm• Definition- An animal, such as the earthworm,
whose body is made up of connected sections, or segments.
• Body Systems- Bilateral symmetry, 5 enlarged tubes act as the heart, brain, and breath though thin moist skin. 2 openings 2 sets of muscles.
• Reproduction- Sexual they both lay eggs when they mate, eggs get fertilized.
• Food- Food goes through mouth ground into partials, digested out
• Habitat- Moist warm soil.• Predators- Snakes• Adaptations- Muscles extend or release to move.

ArthropodsBlack Widow Spiders• Definition- An animal that has jointed
exoskeleton and jointed limbs.• Body systems- Exoskeleton, muscles that contract
and relax, digestive openings, has circulatory, and brain, well developed sight, sound touch.
• Reproduction- Sexually, Females lay fertilized eggs.
• Food- Other animals• Habitat- Almost all live on land.• Predators- They’re food sources for other
animals.• Adaptations- Exoskeleton, largest phylum
