Kingdom Animalia

  1. Multicellular, eukaryotic heterotrophs
  2. Motile, at some time
  3. Reproduce predominately sexually
  4. Nervous system, respond to stimuli
  5. Animalia phyla, 10

Animal Classification 1

  1. Number of germ layers: 2 or 3
  2. Presence or absence of a coelom: coelomate, acoelomate, or pseudocoelomate
  3. Symmetry: asymmetrical, radial, or bilateral (anterior, posterior, dorsal, ventral)

Coelom

  1. Acoelomate- No space between mesoderm and endoderm
  2. Pseudocoelomate- Space between mesoderm and endoderm
  3. Coelomates- Space between mesoderm and mesoderm

Coelom

Phylum Porifera- Sponges

  1. Most primitive, perforated body with dermal pores & spongocoel
  2. Feed by filtering water into pores & out through osculum
  3. Adults are sessile, larvae are motile
  4. Asymmetrical, no body plan or germ layers
  5. Reproduce sexually & asexually

Porifera Classification

  1. Classified by spicule composition
  2. Spongin, a protein
  3. Calcium carbonate, CaCO 3
  4. Silica, SiO 2

Phylum Cnidaria

  1. Includes jellyfish, anemones, & hydra
  2. Radial symmetry with sac body plan
  3. Ectoderm & endoderm with undeveloped mesoderm
  4. Carnivores, use cnidocytes, stinging cells to capture prey

Phylum Cnidaria

  1. Two body forms a. Polyp- sessile b. Medusa- free-living motile
  2. Produce eggs & sperm
  3. Syngamy- mass release of eggs & sperm

Phylum Cnidaria- Hydrazoa

Hydra sp.

Phylum Cnidaria- Hydrazoa

Hydra sp. , cross section

Phylum Cnidaria- Hydrazoa

Obelia sp. , life cycle

Phylum Cnidaria- Scyphozoa

Aglantha sp. , common jellyfish

Phylum Cnidaria- Anthozoa

Montastrea cavernosa, Pineapple coral

Phylum Platyhelminthes-

Flatworms

  1. Bilateral symmetry with 3 germ layers
  2. Acoelomate
  3. Free-living or parasitic
  4. Dioecious or monoecious
  5. Three classes
