Invertebrates - What Are Mollusks?

Mollusks are soft-bodied animals which often live in hard shells. There are over 50,000 species of mollusks.

Examples are:
  • snails
  • slugs
  • squid
  • mussels
  • clams
  • scallops
  • chitons
  • cuttlefish 
  • oysters
  • octopuses

Activity 1

  • Put out an assortment of shells for students to observe.
  • Have students use their senses to observe and examine the shells. (shape, color, texture, etc.)
  • Have students put the shells into groups based on characteristics that they observe. (color, size, shape, texture, etc.)
  • Have students explain what characrteristis they used to group the shells.
  • Older students can try to regroup the shells using different characteristics.
  • Again students should explain what characteristics they used to group the shells.

Activity 2
  • Students can use field guides or pocket guides to identify shells according to scientific classifications.
