Presentation Transcript
3 different groups
3 Different Groups
  • There are three different groups of Mollusks:
  • Gastropods
  • Bivalves
  • Cephalopods
characteristics
Characteristics
  • Mollusks are soft bodied invertebrates
  • They have one or two shells
  • They either live in water or land
  • Gius- the organs in which carbon dioxide from the mollusk is exchanged to oxygen in water
  • They have a thin layer of tissue called mantle
  • They have a layer of mucus on which they slide
  • They have a tongue like organ with rows of teeth

Gastropods

  • Use a radula, a tongue like organ with rows of teeth to obtain food
  • It eats algae
  • Bivalves
  • Eats phytoplankton
  • Use gills for eating tiny food particles
Food
slide5
Food
  • Cephalopods
  • Eats fish, crustaceans, worms, and other mollusks
habitat
Habitat
  • Gastropods
  • Lives best in deep shallow water
  • Reefs and sea grass
  • Cephalopods
  • Lives in rocks, corals, or burrows
  • Bivalves
  • Lives mostly in moist areas
facts
Facts
  • The body plans of mollusks include a mantle, visceral mass, head and foot
  • Gastropods typically have one shell, a foot, and eat using a radula
  • Bivalves have a hinged two- part shell, a muscular foot, and eat by filtering their food from the water
  • Cephalopods have a head, a foot which has been modified into tentacles, and a well developed nervous system
facts1
Facts
  • Mollusks are food for many animals, have commercial uses, and are used for research
  • Mollusks fossils date back more than 500 million years ago
  • A natural pearl begins its life inside an oyster
reproduction
Reproduction
  • Mollusks have reproductive organs
  • The male mollusk goes behind the female
  • He then puts “stuff” into the female
  • The female can hold the “stuff” for as long as she wants, until the babies are ready to come
