More info that was promised-
What is likely happening is that the sharks can smell the blood but it's just not in a quantity that is interesting to them especially since they don't love human blood that much (btw, I spoke with a marine biologist and mammal blood is all the same from a chemical marker stand point so cow blood is a suitable substitute for human blood). If I did the experiment again, I would want to test human blood vs. fish blood.
This is the most definitive study done to date in a control lab environment on what is least and most interesting to them: The Biology of Sharks and Rays Peter A. Klimley and Steven Oerding; ISBN-13: 9780226442495. Particularly pages 134-140. Figure 6.7; Table 6.2

Summary: I've always wanted to test if sharks can really smell a single drop of blood in the water from 1 mile away. So I went to the Bahamas in shark infested waters and set up an experiment to get to the bottom of things.

  • ja, aber nicht das von Menschen, gehört nicht in ihr natürliches Beuteschema und somit können sie damit wohl nichts anfangen. Wenn er aber wen anfrisst, wegen Verwechslung und auf den Geschmack kommt oder ausgehungert ist kann es vielleicht anders sein. Oder man füttert die über Jahre hinweg an dann ändert sich das vielleicht und Schwimmer usw. werden gezielt angegriffen.

  • I think the time has to be considered in terms of the blood molecule transport speed in seawater. Sharks can detect the presence of the blood and trace back to the source only when they sense the hemoglobin. It takes time for blood to transport to a distance.
