3. Sponges Ex: Venus-flower basket sponge
Definition: A type of animal that filters the water it lives in to get food
Body Systems: It can spread over rock, not symmetrical, varies in sizes depending on species
Reproduction: "Buds and braches grow from a parent sponge. These buds break off and grow into new sponges.” Another way is that a larva hatches and attaches to a hard surface
Food: Small whip like cells grab food, inside cells collect them, and those cells inside can make a kind of skeleton
Habitat: Bottom of the ocean floor, surface of the water, rocks, and large animals
Predators/Problems: Parrotfish eat sponges and our man made creations and materials we use(oil can kill their food, pollution, and a drunk person driving off the road and falling into the water in their car or motorcycle)
Adaptations/Fun Facts: The small whip like cells help pump water into it’s body and grab small food particles MB

4. Cnidarians Jellyfish AU
Definition: A phylum of invertebrates who have tentacles to sting its prey or predators.
Body systems: Cnidarians have radical symmetry but they don’t have any internal organs but instead have organized cell tissue that work together
Reproduction: Cnidarians reproduce both sexually and asexually by spraying the eggs with sperm then the jellyfish breaks off from its parent
Food: Cnidarians are carnivores that use there stingers to paralyze their prey.
Habitat: Cnidarians live in salt and fresh water territories
Predators: the predators of the jelly fish are leather back sea turtles
Fun Facts: A fun fact is that Cnidarians only have one digestive opening. AU

5. Flatworms Ex: tapeworms
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: Two nerve cords extend the length of the body but can only sense light and dark
Reproduction: Sexual reproduction, they spread their cells into the water for eggs to form
Food: Only one tube that sucks food then disposes of the waste
Habitat: Under rocks, in mud, fresh water environments, uncooked meats
Predators/Problems: Oil, things in the water that cleans like chlorine, and a knife will only make more
Adaptations/Fun Facts: To be able to grow
Back it’s head or tail

6. Nematodes Ascaris+
Definition: An animal with a round tube like body and two digestive openings
Body systems: nematodes have bilateral symmetry and muscles along their body to move. Reproduction: nematodes reproduce sexually
Food: nematodes eat bugs or dying plant matter.
Habitat: nematodes live in the ground or other organisms
Predators and problems: nematodes are eaten by anything bigger than it.

7. Annelids Earth worms+
Definition: an animal such as an earth worm who’s body is made up of connected sections or segments.
Body systems: annelids have bilateral symmetry they breath through their skin annelids also have brains and five tubes for hearts they also have a nerve cord and move by contracting muscles
Food: annelids eat decaying plant and animal matter.
Habitat: all annelids live in the soil.
Predators and problems: many birds reptiles and amphibians eat earth worms.
Adaptions and fun facts: earth worms body systems differ in many ways from regular worms. AU

8. DS
Mollusks/Ex. snail
Definition: an animal with a soft body with no bones
Body systems: they have well developed nervous systems that enable them to move quickly
Reproduction: They reproduce sexually by releasing
eggs and sperm into the water where the eggs can fertilized
Food: mollusks (that live in the water) catch small sea life. For ex. A octopus has tentacles for grabbing and pulling the fish into it’s mouth
Habitat: some mollusks live on land and some live in water. So mollusks can be found all over the world
Predators/Problems: Oil, pollution, and other echinoderms along with us
Adaptation: A squid’s adaptations are, it can use it’s jet motion to get away quickly. And it can squirt out inky fluid

9. Arthropods/ex.spider DS
Definition: an animal that has joints exoskeleton and jointed limbs
Body systems: muscles inside the exoskeleton controlled too law complex movement
Reproduction: they reproduce sexually by reproduce sexually by releasing eggs and sperm into the water where the eggs can be fertilized.
Food: they eat meat and plants, they have 2 opens one for the food too go down, and one for waste
Habitat: any environment that supports life.
Predators: Humans are the only thing that harm them.
Adaptation: the 3 groups of arthropods are insects, arachnids, crustaceans

10. Echinoderms Ex: Sand Dollar
Definition: An invertebrate that has an internal skeleton and spines that are part of it’s skin
Body Systems: No brain(that’s a no brainer), nerves that let it move and eat though, limbs that grow from the center
Reproduction: Releases cells into the water for eggs to form or if it grows it’s limbs back
Food: Starfish eat mussels, first it wraps I’s limbs around, then it will pry the shell open to then wrap it’s stomach around to digest it, sand dollars eat small organic particles
Habitat: Inside sea water, rocks, or the ocean floor
Predators/Problems: Oil, pollution, cars/motorbikes(just random)
Adaptations/Fun Facts: Regeneration of limbs and
camouflage to starfish
