NOTES: Powerpoint:

** Classifying Animals into Phyla ** **Phylum Porifera:** sponges Collections of individual cells, with no tissues or organs, and no nervous system or skeleton. **Phylum Cnidaria:** jellyfish, sea anemones, coral Usually very beautiful forms, their bodies are two-layered and symmetrical in a circular fashion with rudimentary organs and systems, but no skeleton. **Phylum Platyhelminthes:** flatworms, tapeworms Their bodies are symmetrical in a left/right fashion (like humans). Their bodies have three layers and have very rudimentary nervous tissue. **Phylum Nematoda:** roundworms They are symmetrical like the flatworms and have three body layers. Many are beneficial soil organisms, whereas some are parasites (such as hookworms and pinworms). **Phylum Annelida:** segmented worms These have bodies similar to other previous worms but with some more advanced characteristics, including sensory organs and a relatively developed nervous system. Their bodies are divided into segments; earthworms are the best example of animals in this category. **Phylum Echinodermata:** sea stars and sea urchins Their bodies have a circular symmetry with five body parts being arranged around a central axis. They have calcium spines or plates just under the skin and a unique water vascular system that is a series of fluid-filled vessels that provide body support and allow for locomotion. **Phylum Mollusca:** snails, clams, and octopuses These have a well-developed circulatory system, nervous system, and digestive system; octopuses have particularly well-developed brains with highly maneuverable tentacles. **Phylum Arthropoda:** crustaceans, spiders, and insects This phylum has more species than the other phylums, mostly because of all the insect species. Their bodies have exoskeletons, and most undergo metamorphosis (a transformation that allows them to grow by shedding their exoskeleton and developing into a larger or more adult form). They often have specialized body parts (antennae, pinchers, etc.), and they are well adapted to many environments. **Phylum Chordata:** amphibians, reptiles, fish, birds, and mammals (including humans) These are the most familiar animals, and we all share four characteristics: a notochord that often develops into the vertebral column in vertebrates; a nerve cord that runs along our backs; gill slits at some point in our development; and a tail or at least a vestigial tail (humans have the tailbone or coccyx). || Science Textbook Student Online Edition ACCESSCODE:  DB6A0AB209     []   Self-check Quizzes [] [|Chapter 12: Introduction to Animals]
