Clams, octopi, oysters, scallops, slugs, snails, and squid are all mollusks. Mollusks have soft bodies and either a 1 shell or 2 shells. Clams and scallops are bivalves, which are 2-shelled mollusks.
The phylum is Mollusca - all clams are mollusks, like any shelled bivalve. Snails and slugs are also mollusks.
They were invertebrates. They were shelled molluscs, basically large sea snails.
clams, oysters and scallops are organized into the group called bivalves. they are two-shelled, slow moving organisms
The first shelled organisms were likely early mollusks such as the small shelled creatures known as brachiopods or the ancestors of modern snails and clams. Their shells provided protection and support for their soft bodies, helping them adapt to various environments and thrive in the ancient seas.
The answer is very simple. Jellyfish are cnidarians. Octopi are not. Because the octopus does not have the same head structure as the jellyfish. Also octopi are cephalopods. They are closer to mollusks in the bases of things but the tentacles are different. Just because they have tentacles does not mean they are in the same categories. But octopi and squid are in the same category as mollusks such as snails. That is a different story though. But that is why they are not the same.
Yes, mollusks includes snails and slugs.
Soft-bodied invertebrates are called mollusks, mollusks are snails, snails are mollusks because snail have soft bodies.
The only mollusks that are Gastropoda are slugs and snails.
neither. snails are considered mollusks
The term "ammonites" applies to extinct mollusks which resembled octopi and squid, but with a hard exuded shell as with snails and crustaceans. They exist as fosil records from about 65 million to 400 million years ago.
No, mollusks (clams, snails, squid, etc.) are animals.
