Yes, they do.
Squids have three hearts. Two of the hearts pump blood to the gills for oxygenation, while the third heart pumps oxygenated blood to the rest of the body.
Humans have red hearts because we have red blood. Squids have white hearts because their blood is white.
Squids have three hearts to help pump oxygen-rich blood to their tissues more efficiently. Two of the hearts pump blood to the gills for oxygenation, while the third heart pumps oxygenated blood to the rest of the body. This adaptation helps support their active, fast-swimming lifestyle.

Yes their blood is red
No they do not.
Squids have three hearts: two branchial hearts and one systemic heart. The branchial hearts pump blood to the gills where oxygen is taken up. Blood then flows to the systemic heart where it is pumped to the rest of the body.
Since squids do not have haemoglobin they use haemocyanin to bind and transport oxygen throughout their body.
squids, octapi, oysters, and clams.
Squids do not actually have blood. They have a substitute for blood, called hemolymph. It is just a fluid with oxygen and other nutrients in it.
Yes, some animals have two hearts. For example, cephalopods like squids and octopuses have a main systemic heart that pumps oxygenated blood through the body, and a branchial heart that pumps deoxygenated blood to the gills to be oxygenated.
