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 symmetry
• Reproduction- 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- Fish
• Adaptations 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 symmetry
• Nervous- nerve net
• Respiratory- they do not have one
• Circulatory- 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.

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 theyre 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- Theyre food sources for other
  animals.
• Adaptations- Exoskeleton, largest phylum
