Classifying Ocean Animals

Science · Ocean Life · conceptual

Classify ocean animals into major groups: fish (breathe through gills, have scales), marine mammals (breathe air, warm-blooded, feed milk), and invertebrates (no backbone — jellyfish, octopuses, crabs, starfish)

What mastery looks like

  • Sort ocean animals into fish, marine mammals, and invertebrates
  • Give defining features of each group (gills vs lungs, backbone vs none)
  • Correctly classify at least two animals in each group

Check your understanding

If Classifying Ocean Animals saw pictures of a tuna, a seal, and a jellyfish, could they sort them into fish, marine mammals, and invertebrates, and explain what makes each group different?
