  3. Domain Bacteria Archaea Eukarya Animalia Kingdom Phylum • Porifera (sponges) – NO BODY SYMMETRY • Cnidaria – RADIAL SYMMETRY; NEMATOCYSTS (STINGING CELLS) • Class Hydrozoa (small, juvenile medusa stage, adult polyp stage) • Order Siphonophora (ex. Portuguese man o’war) • Class Scyphozoa (“jellyfish”, adult medusa stage, juvenile adult stage) • Class Anthozoa (polyp stage only; corals, sea anemones, sea fans) • Ctenophora (comb jellies) – 8 ROWS OF CILIA, COLLOBLASTS (STICKY CELLS) • Platyhelminthes (flatworms) – BILATERAL SYMMETRY, ORGAN SYSTEMS • Nemertea (ribbon worms) – DIGESTIVE TRACT & CIRCULATORY SYSTEM • Annelida (segmented worms) – SEGMENTATION, DIGESTIVE TRACT AND CIRCULATORY SYSTEM • Class Polychaeta (bristle worms) • Class Pogonophera (bearded worms) • Mollusca – MANTLE (SECRETES SHELL) • Class Gastropoda (snails) • Class Bivalvia (“two hinges”; clams, scallops, mussels, oysters) • Class Cephalopoda (“head foot”; nautilus, squid, cuttlefish, octopus

  4. Domain Bacteria Archaea Eukarya Kingdom Animalia Phylum • Arthropoda – “JOINTED FOOTED”, EXOSKELETON • Subphylum Crustacea (crabs, lobsters, shrimp, barnacles, amphipods, isopods) • Subphylum Chelicerata (horseshoe crab) • Echinodermata – “SPINY SKIN”, PENTAMEROUS SYMMETRY (sea stars, brittle stars, sea urchins, sea cucumbers, crinoids) • Chordata – DORSAL HOLLOW NERVE CORD, GILLS/PHARYNGEAL SLITS, NOTOCORD, POST-ANAL TAIL • Subphylum Urochordata – four chordate characteristics during embryonic development only • Subphylum Cephalochordata – four chordate characteristics throughout entire life • Subphylum Vertebrata • Agnatha (jawless fish; lamprey, hagfish) • Chondrichthyes (cartilaginous fish; sharks, skates, rays, chimeras) • Osteichthyes (bony fishes) • Class Reptilia (reptiles) • Class Aves (marine birds) • Class Mammalia (marine mammals)
