  1. What phylum and Class is it in?

  2. Phylum: MolluscaClass: Gastropoda

  3. Phylum: MolluscaClass: Cephalopoda • Cuttlefishes: similar to squid’s anatomy and swimming capabilities.  • The difference: cuttlefishes have a small, curved shell covered by the mantle (the cuttlebone often seen in bird cages) whereas squids have a vestigial skeleton consisting of a curved plastic-like support called a pen.

  4. Phylum: MolluscaClass: Bivalvia • Latin;  bi=two   -  two plates (Two halves to the shell)  

  5. Phylum: MolluscaClass: Cephalopoda

  6. Phylum: MolluscaClass: Gastropoda

  7. Phylum: MolluscaClass: Gastropoda • conch (pronounced "konk" (IPA: /kɒŋk/) or "konch" (IPA: /kɒntʃ/)) • a sea-dwelling mollusk, more specifically, a marine gastropod. • note that many other gastropods have common names using conch, such as the Horse Conch (Pleuroploca gigantea).

  8. Phylum: MolluscaClass: Bivalvia The name oyster is used for a number of different groups of mollusks which grow for the most part in marine or brackish water. The shell, usually highly calcified, surrounds a soft body. Gills filter plankton Strong adductor muscles hold the shell closed. Some of these groups are highly prized as food, both raw and cooked

  9. Phylum Annelida • Giant Gippsland earthworm (Megascolides australis), is one of the most fascinating of Australia's 1000 native earthworm species. average at 80 cm long and 2 cm in diameter. • dark purple head and a pinkish-grey body. • live in the subsoil along stream banks and some south or west facing hills of their remaining habitat in Victoria, Australia. • Live in deep burrow systems and require water in their environment to respire. • rarely leave their moist burrows. • Long lifespans for invertebrates and can take 5 years to reach maturity. When these worms hatch they are already 20 cm long. • They can sometimes be heard in their habitat making gurgling sounds underground.
