Distinguishing features of Phylum Mollusca |
-Visceral mass enclosing organs -Mantle; protective and usually secretes shell -Muscular foot used in locomotion |
|
Label this diagram What are the plates also called? How does this animal live? What adaptations enable it to live this way? |
Valves It is sessile on rocky substrates, it has a muscular foot to grip onto substrates, a hard shell, and the ability to "roll up" if disturbed |

Full taxonomy What are the holes at the top of the shell for? |
Phylum: Mollusca Class: Gastropoda Subclass: Prosobranchia Genus: Haliotis Other groups; Archaeogastopoda Abalones live in the rocky intertidal zone an use their muscular foot to seal themselves to the rocks, the holes allow them to maintain water flow so they can breath |
|
Full taxonomy |
Phylum: Mollusca
Class: Gastropoda Subclass: Prosobranchia Other groups; Archaeogastopoda The hole in the shell allows water to enter and exit the mantle cavity for respiration |
|
Full taxonomy What does it eat? How does it eat? |
Phylum: Mollusca
Class: Gastropoda Subclass: Prosobranchia Genus: Polinices Species: lewissii Other groups; Neogastopoda It eats bivalves. It smothers them with its mantle, then using glandular secretions it erodes a hole in the shell, then it inserts its radula an maneuverable proboscis into the hole to eat the meat inside. |
|
What is the round dark structure? What is it's function? |
The operculum allows the snail to "seal" its shell, and protect itself from desiccation and predation |

What is this structure? What is it for? |
A radula, it is used to rasp food |

|
What are: cerata, rhinopores, and branchial plumes |
Cerata are projections on the mantle od Aeolid nudibranchs. They are used in gas exchange, act as extensions of the digestive system, they hold kleptocnidae, and sometimes mutualistic algae Rhinopores are chemosensory tentacles Branchial plumes are retractable gills used in gas exchange |
|
Full taxonomy What adaptations does this animal have to survival in the terrestrial environment |
Phylum: Mollusca Class: Gastropoda Subclass: Pulmonata Genus: Ariolimax Species: columbianus The mantle cavity it modified to serve as a lung, with the pneumostome acting as an opening. Excessive mucous production is used to prevent water loss, for locomotion, and "slime trails" |

|
Label the structures and give their functions |
1: Foot; used for burrowing 2: Siphon; water enters and exits the bivalve 3: Labial palps; Used to sort material brought into the bivalve, sand is ejected a pseudofeces and food is brought to the mouth 4: Gills; cillia on gills generate water currents, gills also function in gas exchange and food particle collection |
