What phylum do clams snails and squid belong to?
Phylum Mollusca
Clams, Snails, and Squid: Phylum Mollusca, Class Pelecypoda. Pelecypods have two shells, or bivalves, that protect the soft parts of the animal.
What phylum do gastropods bivalves and cephalopods belong to?
phylum Mollusca
Although gastropods and cephalopods both belong to the taxonomic phylum Mollusca — more commonly known as mollusks — that doesn’t mean they’re similar.
What phylum has bivalves?
Clams, mussels, oysters, and scallops are members to the class Bivalvia (or Pelecypodia).
Which phylum has bivalves octopuses squid and sea snails?
Cephalopoda
Classification
| Class | Major organisms |
|---|---|
| Gastropoda | all snails and slugs including abalone, limpets, conch, nudibranchs, sea hares, sea butterflies |
| Bivalvia | clams, oysters, scallops, geoducks, mussels, rudists† |
| Polyplacophora | chitons |
| Cephalopoda | squid, octopuses, cuttlefish, nautiluses, Spirula, belemnites†, ammonites† |
What are the six major classes of living molluscs?
Mollusks can be segregated into seven classes: Aplacophora, Monoplacophora, Polyplacophora, Bivalvia, Gastropoda, Cephalopoda, and Scaphopoda. These classes are distinguished by, among other criteria, the presence and types of shells they possess.
Is a scallop a gastropod?
Edible molluscs are harvested from saltwater, freshwater, and the land, and include numerous members of the classes Gastropoda (snails), Bivalvia (clams, scallops, oysters etc.), Cephalopoda (octopus and squid), and Polyplacophora (chitons).
Do molluscs have brains?
Molluscs, with the exception of the most highly developed cephalopods, have no brain in the strict sense of the word. Instead, the cell bodies (pericarya) of nerve cells are concentrated in nerve knots (ganglia) in important parts of the body. In gastropods, the ganglia originally have been dispersed over the body.
How many cephalopods are there in the phylum Mollusca?
Phylum – Mollusca (Gastropods, Bivalves, Cephalopods) There are more than 50,000 species in this phylum. Mollusks are invertebrates and include octopus, squid, snails, slugs, clams, and oysters and many others. As diverse as this phylum is, all its animals include three physical traits.
What kind of mollusc are snails and clams?
Clams, Snails, and Squid: Phylum Mollusca, Class Gastropoda. Gastropods is the group of molluscs that includes the snails.
How are the seven classes of mollusks classified?
Key Points Mollusks can be segregated into seven classes: Aplacophora, Monoplacophora, Polyplacophora, Bivalvia, Gastropoda, Cephalopoda, and Scaphopoda. Class Aplacophora includes worm-like animals with no shell and a rudimentary body structure. Members of class Monoplacophora have a single shell that encloses the body.
Where do clams, snails, and squids live?
Clams, Snails, and Squid: Phylum Mollusca, Class Gastropoda Gastropods is the group of molluscs that includes the snails. Many types secrete a single coiled or uncoiled shell for protection, and these shells may be found as fossils. Some species spend their lives crawling along the sea floor, eating algae or debris from rocks and bottom sediments.

What makes a bivalve different from a gastropod?
Unlike the gastropods that have one shell, or are lacking a shell altogether, bivalves are animals that have two shells, or valves. The valves, which hinge together on one side and are opened and closed by strong muscles, provide these animals with protection from predators.
