  • in what part of the tail is this? is it in the tail?

  • Yes they do. Although this comment is probably way to late for your essay or whatever you're doing since you posted this 8 months ago.

  • does anyone know whether oxygenated and deoxygenated blood mix in fish?

  • The human circulatory system wins out in one respect. Our 4 chambered mammalian heart is better at separating oxygen-rich from oxygen-poor blood. In the 2-chambered heart of a fish, the two types of blood mix, which means less efficient oxygen delivery.

  • fascinating...lol, can any1 tell me whether the human circulatory system is better or the fish's circulatory system in terms of effectiveness relaive to size

  • cool
