The circulatory system of octopuses is closed, meaning that blood is contained within vessels and circulated efficiently throughout the body, allowing for better oxygen delivery to their active tissues. In contrast, clams possess an open circulatory system, where blood flows freely through cavities and is not entirely contained within vessels, which can result in slower oxygen transport. Additionally, octopuses have a three-hearted system: two hearts pump blood to the gills for oxygenation, while the third pumps it to the rest of the body. Clams, on the other hand, rely on a simpler system that does not require multiple hearts for circulation.

Compare the circulatory system of each of the three major classes of mollusks?
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.

Mollusks are further divided into classes, with clams and snails belonging to the class Bivalvia and Gastropoda, respectively, while octopuses belong to the class Cephalopoda.
Does oysters have a closed circulatory system?
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.
What is an example of a mollusca?
Snails, slugs, octopuses, squids, clams, mussels, and oysters.
What do the gills do in a clam?
clams use gills to take oxegen out of H2O so their heart can carry on with the circulatory system.
Why is an octopus more closely related to a clam than a lobster?
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.
How do octopuses eat?
