Mollusks

Mollusks


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


Mollusks

  • 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


Mollusks

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
