Chitons have more iron in their circulatory fluid (hemolymph) than any other animal studied to date.

Their blood equivalent, #hemolymph, changes its physical properties, sealing wounds in about a minute because the watery hemolymph that initially bleeds out turns into a viscoelastic substance outside of the body and retracts back to the wound. https://arstechnica.com/science/2024/04/how-insect-blood-stops-bleeding-fast/
How insect blood stops bleeding fast

Their blood equivalent, hemolymph, forms a viscoelastic fluid that covers wounds.

Blood is a remarkable material: it must remain fluid inside blood vessels, yet clot as quickly as possible outside them, to stop bleeding. The chemical cascade that makes this possible is well understood for vertebrate blood. But hemolymph, the equivalent of blood in insects, has a very different composition, being notably lacking in red blood cells, hemoglobin, and platelets, and having amoeba-like cells called hemocytes instead of white blood cells for immune defense.
