|
Porifera |
Benthic- live at bottom of aquatic environments Suspension Feeders Sessile adults, produce larvae that swim with aid of cilia Sponges |
|
|
Cnidaria |
Radially symmetric diploblasts, some are tiploblastic Bilaterally symmetric larvae of bilateral as adults, Incomplete gut- gastrovascular cavity Polyp and Medusa form Outerskeleton of calcium carbonate Jellyfish, Corals, Anemones, Hydriods |
|
|
Cnidaria Feeding, Movement, Reproduction |
Nematocysts- Cnidocyte used to capture prey Host Photosynthetic dinoflagellates Polyp- Gut is hydrostatic skeleton that moves by contraction and extension Asexually reproduce by budding, fission, and fragmentation. |
|
|
Bryozoans |
Protostomes Zooids- suspension feed on plankton using alophophore Sessile- larvae dispense Hermaphroditic |
|
|
Rotifera |
Damp soil, marine, freshwater, important plankton have a coelom Cluster of cilia called a corona at anterior end for suspension feeding sessile parthogensis- females produce unfertilized eggs by mitosis; when hatch into new asexually produced individuals. Rotifers |
|
|
Platyhelminthes |
Flat Worms Turbelleria: Free living flatworms, dugesia Cestoda: endoparasitic tapeworms Trematoda: endo/ectoparasitic flukes, responsible for schistosomiasis Monogenea: ectoparasites that parasitize fish |
|
|
Platyhelminthes Feeding, Movement, Reproduction |
"Blind" digestive tract that has only one opening Undulation movement Complex life cycles with definitive and intermediate hosts Unsegmented, lack a coelom, no blood vessels, high surface area to volume ratio Aquatic and moist environments |
|
|
Annelida |
Segmented Worms Have a coelom Polychaetes- suspension feed Oligochaetes- deposit feeding in soils Hydrostatic skeleton for movement Asexual reproduction Leeches |
|
|
Bivalvia |
Clams, Mussels, Scallops, Oysters Two separate parts made of calcium carbonate Suspension feeders Muscular foot for movement
|
|
|
Gastropoda |
Snails, Slugs, Nudibranchs Belly feet, have shells. Slugs and nudibranchs don't have shells but use toxins for protection Herbivores or detrivores Contractions to creep
|
|
|
Cephalopoda |
Nautilus, Cuttlefish, Squid, Octopus Have a head and tentacles HIghly intelligent Hunters Courtships for sexual reproduction |
|
|
Nematoda |
Round worms Unsegmented, pseudocoelom, tube-within-a-tube body plan, no appendages, thick elastic cuticle to shed Pinworms: live in intestines Wuchereria bancrofti- elephantiasis Trichinella: trichoinosis Move with hydrostatic skeleton- undulation |
|
|
Myriapoda |
Millipedes and Centipedes Segments with 1/2 paris of feet per segment Millipedes are detrivores, centipedes have poisonous fangs |
|
|
Insecta |
Terrestiral, thorax, abdomen, head 3 pairs of walking feet most diverse phylum Insects |
|
|
Crusacea |
Shrimp, Lobsters, Crabs, Barnacles, Isopods, Copepods Cephalothorax, abdomen. Carapace exoskeleton Have limbs for movement, barnacles are sessile |
|
|
Chelicerata |
Sea Spiders, Daddly long legs, Horshoe crab, mites, ticks, scorpions, spiders Prey on other animals Move with muscles attached to exoskeleton Have paired appendage- Chelicerae near mouth |
|
|
Protostome development |
mouth first |
