In cephalopods like octopuses, the circulatory system is closed, with blood contained in vessels. Bivalves like clams have an open circulatory system where blood is pumped into a hemocoel. Gastropods, such as snails, have a mix of closed and open circulatory systems, with a heart that pumps blood through vessels but also into spaces around organs.
the like to eat clams
Blood vessels & heart, not sure fo the rest
Usually octopuses eat crabs, clams and some other fishes too.
No oysters do not have a closed circulatory system. They have something known as a open circulatory system. They are similar to that of fish. They have something similar to that of the gills in fish so that they are able to function in the aquatic environment. The closed circulatory systems, are usually in the terrestrial animals such as mammals, birds etc.
Snails, slugs, octopuses, squids, clams, mussels, and oysters.
clams use gills to take oxegen out of H2O so their heart can carry on with the circulatory system.
Both Clams and Octopuses are Mollusks. Clams are under the subphylum Bivalves, and octopuses are cephalopods. Lobsters on the other hand, are not Mollusks. They are crustaceans. Also, an obvious difference is the lobsters exoskeleton.
Octopo et mainly shellfish, like lobster sometimes, clams, and crab.

Mollusca is a kingdom of animals that includes a diverse group of invertebrates such as snails, clams, and octopuses.
The organs of clams are located inside the shell (of course) and under the mantle, which is a protective membrane that coats the inside of the shell. When I disected clams in Biology, we opened them up, peeled back the mantle and there were all the organs.
