Can blood from a cut attract animals during a Lombok to Sumbawa whale shark tour?

No, blood from a cut does not attract whale sharks or pose any risk of drawing dangerous animals during the tour. Whale sharks are filter feeders that consume plankton and tiny organisms — they are not predators and do not hunt by scent or blood. Their biology is completely different from that of predatory sharks that might be attracted to blood in other marine contexts. The tiny amount of blood that might enter the water from a minor cut is immediately diluted by the ocean and is biologically irrelevant to a whale shark.

The other marine life in Saleh Bay — dolphins, turtles, fish — is also not attracted to human blood. There are no predatory shark species in the encounter area that would respond to blood signals. The local guides have hosted thousands of guests and have never encountered a situation where a guest’s minor bleeding caused any animal behavior change or safety concern.

That said, it is still good practice to cover fresh or bleeding wounds with a waterproof bandage before entering the water, primarily to protect yourself from infection and to keep the wound from stinging in the salt water. If you have a significant wound that is actively bleeding, consider staying on the boat to watch the encounter. The animal behavior aspect is a non-issue; your personal comfort and wound care are the real considerations.
