  • Body symmetry types: asymmetrical, radial, and bilateral
  • Diploblastic animals have two germ layers, triploblastic have three

  • Porifera: Simplest multicellular animals with unique water canal system
  • Cnidaria: First animals with tissues and stinging cells (nematocysts)
  • Platyhelminthes: First bilaterally symmetrical animals with organs

  • Arthropoda: Most successful phylum with exoskeleton and jointed appendages
  • Mollusca: Diverse group with shell, mantle, and radula adaptations
  • Echinodermata: Unique water vascular system and radial symmetry in adults

Common Mistakes to Avoid

All bilaterally symmetrical animals are coelomates

Radial symmetry means the animal is primitive and simple

Sponges have no organization at all since they lack tissues
