Cephalopodas: squids, chambered nautilus, octopus. Its blood contains the copper-rich protein hemocyanin for transporting oxygen (compared to iron-based hemoglobin, which is red). They have 3 hearts, 2 for pumping blood to each of its two gills, and one to the rest of the body.

Earthworms have 5 hearts, and have blood based on "erythrocruorin", a massive protein containing iron.
Fish and frogs (amphibians) have only one heart; and its blood is red (as with all vertebrates -- animals with a backbone.) However, the heart of a fish has two chambers. The hearts of amphibians and reptiles (except crocodilians) have 3 chambers. Crocodilians and mammals have 4-chambered hearts. http://library.thinkquest.org/C003758/Development/fish.htm
