Sponge, Cnidarian, Echinoderm
Asymmetrical filter feeders with no nervous system.
What are sponges?
These worms are the first organisms to develop bilateral symmetry.
What are flatworms?
This phylum of animals includes octopi, clams, and snails.
What are mollusks?
This type of fish includes sharks and rays.
What are cartilaginous fish?
These organisms are not able to reproduce without a body of water because their eggs do not have shells.
What are amphibians?
These organisms are the most highly developed of all of the animal groups. It makes sense because they spend the longest time caring for their young.
What are placental mammals?
This is a body plan in which body parts repeat around the center of the body in a circular pattern.
What is radial symmetry?
These are the simplest organism in the animal kingdom.
What are sponges?
These organisms have a psuedocoelom.
What are roundworms?
These organisms have exoskeletons and open circulatory systems.
What are arthropods?
Large-mouth bass, clown fish, perch, and catfish are examples of this type of fish.
What are bony fish?
These two groups of organisms have amniotic eggs with shells.
What are reptiles and birds?
These organisms carry young in an external pouch after birth.
What are marsupials?
This is a fluid-filled body cavity lined with a mesoderm (where circulatory, respiratory, muscular, excretory, and reproductive systems often are).
What is a coelom?
These are the two types of animals with radial symmetry.
What are cnidarians and echinoderms?
These organisms can reproduce sexually or asexually (through regeneration after being sliced in half).
What are flatworms?
One example of this phylum is the Atlantic Horseshoe Crab, Limulus polyphemus.
What are arthropods?
Many of these type of fish are parasites or detritivores.
What are jawless fish?
These two groups of organisms have a cloaca for excretion, digestion, and reproduction.
What are reptiles and birds?
Wombats, koalas, and kangaroos are examples of this type of animal.
What are marsupials?
This word means that an animal has a backbone.
What is a vertebrate?
These organisms are motile and they have tube feet that help them move and do excretion.
What are echinoderms?
These organisms are the first organisms to have a closed circulatory system.
What are annelids?
These organisms are motile, and they use a foot for "walking" or siphon for water propulsion.
What are mollusks?
This group of organisms have a nerve cord, but no spine. One example is tunicate.
What are nonvertebrate chordates?
These organisms have gills when they are born, but they develop lungs as they grow.
What are amphibians?
These mammals have a cloaca, which is where they lay eggs (and do excretion and digestion).
What are monotremes?
This word means that the organism has a brain or head. Most organisms with this characteristic also have bilateral symmetry.
What is cephalization?
These organisms don't have blood, but they have a water vascular system that helps with circulation of oxygen.
What are echinoderms?
These two types of worms do respiration and circulation through diffusion.
What are flatworms and roundworms?
These organisms are motile and they have jointed appendages to help with movement.
What are arthropods?
These two groups of fish have kidneys, gills, and closed circulatory systems.
What are cartilaginous fish and bony fish?
All of these organisms have feathers, but not all of them can fly.
What are birds?
What are placental mammals?
This is an organism that feeds on plant and animal remains and other dead matter.
What is a detritivore?
