Animal Diversity I

  1. Phylum Porifera
    Grantia (3), Scypha (2), Leucosolenia (2), Spongilla, Commercial sponge, Venus Flower; lack true tissue/body cavity (spongocoel), amoebocytes help with digestion, osculum is the opening, choanocytes are collar cells that generate a water current

  9. Phylum Cnidaria
    consists of the classes Hydrozoa, Scyphozoans, and Anthozoans; dipoblastic; radially symmetrical, have tissues, exhibit behavior; no learning; old Eumetazoa; one opening
  10. cnidocyte
    Cnidarian; found on tentacles, are cells for defense and prey capture, contain cnidae that explode out
  11. nematocysts
    Cnidaria; organelles within cnidoytes that eject a stinging thread

  20. Phylum Platyhelminthes
    flatworms; flattened dorsoventrally; tripoblastic BUT acoelomates; include class Turbellaria (planarians), Trematodes (flukes), and Cestoidea (tapeworm)
  21. Class Turbellaria
    Planarians; have light-sensitive eye spots and nerve nets in head that connect to a ventral nerve cord; can learn; are hermaphrodites; body covered by ciliated epidermis

    sheep liver fluke; white inside, gray (looks a little dotted) outside, looks like a thinner leech; class Trematoda
  25. Image Upload 18
    oriental liver fluke; class Trematoda
  26. Image Upload 19
    Taenia pisiformes; class cestoidea; this is really just the scolex (from top to bottom, hooks, rostellum and scolex), the rest of the body looks like rectangular segments and these house the reproductive organs that break off and spawn [budding zone]
  27. Phylum Annelida
    consists of class Polychaetes (clamworms), class Oligochaeta (earthworms) and class Hirudinea (leeches); segmented worms whose bodies are a series of fused rings; are COELOMATES
  28. Class Polychaetes
    include the clamworm and sea mouse; marine; hermaphroditic; each segment has a pair of PARAPODIA, used for gills and locomotion (in phylum Annelida)

    preserved clamworm, Nereis; class polychaetes

    preserved sea mouse; class polychaetes; in phylum Annelida
  31. Class Oligochaeta
    earthworms; have chaetae made of chitin for traction and burrowing; nervous tissue runs VENTRAL to gastrointestinal tracts; e/a segment is walled of by a septum (in phylum Annelida)

    earthworm anatomy (study in lab book); in phylum Annelida
  34. Class Hirudinea
    most specialized annelids; lost chaetae; hirudin prevents blood from clotting; in phylum Annelida; preserved specimen is gray and flat looking
  35. Phylum Mollusca
    chiton, snail, clam, oyster, mussels, squid, octopus, mollucs; most share 4 common features: have a hard external shell for protection, a mantle that secretes the shell, the visceral mass where most organs are located, and a mucular foot used for locomotion
  36. Class Polyplacophora
    chitons; have a broad foot, 8 dorsal plates and a thing going all the way around called a girdle

    snailz; use radula to feed, have tentacle and occular tentacle to see; have muscluar foot; class Gastropoda; phylum mollusca
  39. class Bivalvia
    in the phylum mollusca; shell divided laterally into 2 halves; are filter feeders, and use gills for feeding/gas exchange; have eyespots to detect shadows; the mantle clings to the shell; include oysters, clams (know anatomy) and mussels
  40. Class Cephalopoda
    phylum Mollusca; includes squid (have tentacles, arms, eye, funnel, collar, mantle and fin), octopus (have suction cups, mouth, arm) and mollusc; have a closed circulatory system, complex brain, well developed sensory organs
