Since squids do not have haemoglobin they use haemocyanin to bind and transport oxygen throughout their body.
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.
All those animals that have haemocyanin as the respiratory pigment have their blood blue when oxygenated. Haemocyanin is the respiratory pigment akin to haemoglobin but hemocyanin has copper as the cofactor instead of iron which you find in haemoglobin. Animals belonging to class crustacea and those belonging to phylum Mollusca have hemocyanin, and hence they have blue blood. Some notable crustaceans are crabs, lobsters, shrimps. Some notable mollusks include Snails, whelks. mytilus, oysters, chitons, squids, sepia, octopus. Limulus, called a horseshoe crab, also has hemocyanin.
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.
The right ventricle of the heart contains deoxygenated blood. It receives blood from the body and pumps it to the lungs for oxygenation.
Squids do not have legs. They have tentacles that are used for capturing prey. Baby squids, known as squid larvae, hatch with small tentacles that continue to develop as they grow.
Circulatory system mainly of closed type, but some emptying into lacunae. Blood is blue and contains haemocyanin.
Both squids and octopuses have blue blood.Their blood is this colour because they use an oxygen-carrying molecule in their blood that contains copper.
it is because they do not have red blood cells .
pinkish green
Yes their blood is red
Yes, they do.
No they do not.
Cuttlefish have three hearts <3 like octopi and Squids; nautiluses have...well, IDK. I'll get back 2 you on that 1. just keep checking that Q, don't worry I'll find an answer =O hehehe...
All animals that have haemoglobin circulatory systems (which contains iron) have red blood, including elephants. Animals with haemocyanin systems (which contains copper) have a blueish blood as there is less oxygen absorption; lobster blood is almost grey as there is so little oxygen. Animals with haemolymphatic circulatory systems have a yellowish colour blood, which includes spiders and some insects. when my teacher said that elephant color is red and when it inhale it is pink understood.
horseshoe crabs do indeed have blue blood, this is because the protein that carries oxygen in their blood is haemocyanin. This protein is a pigment like the haemoglobin in our blood, but instead of using iron to carry the oxygen it uses copper. When iron is oxidised it goes red (hence our red blood) and when copper is oxidised it goes greeny blue (hence the blue blood). horseshoe crab is the animal that has blue blood,,,..but i have no idea of insects having blue blood^_^ All those animals that have haemocyanin as the respiratory pigment have their blood blue when oxygenated.

All human blood contains hemoglobin (spelled differently in different countries) Blood is bright red when oxygenated, and very dark red when oxygen is depleted (in veins) It is never blue. For animals that do have blue blood, ie, molluscs and many arthropods such as Horseshoe Crabs, this is due to the oxygen being carried by copper-containing haemocyanin, rather than iron-containing haemoglobin.
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.
