In general, sharks show little pattern of attacking humans specifically, part of the reason could be that sharks prefer the blood of fish and other common preys.

Do not wander far into the water - especially without assistance. Avoid entering the water with an open wound if you are menstruating as sharks can often smell blood. Swim in areas tended by ...
In addition, the presence of even small traces of blood, recent minor abrasions, cuts, scrapes, or bruises, may lead sharks to attack a human in their environment. Sharks seek out prey through electroreception, sensing the electric fields that are generated by all animals due to the activity of their nerves and muscles.
Xenotransfusion (from Greek xenos-'strange, foreign'), a form of xenotransplantation, was initially defined as the transfer of blood from one species into the veins of another. [1] In most cases, it is a transfer of blood between a non-human animal and a human. However, further experimentation has been done between various non-human animal species.
There were 69 unprovoked shark bites on humans last year, 36 of which were in the U.S., according to the International Shark Attack File report of the museum. Of those 69 attacks, two were fatal ...
While Great White sharks are responsible for most attacks on humans, the team is also planning to test the method on other shark species, including bull and tiger sharks.
Pores are concentrated in the skin around the snout and mouth of sharks and rays, as well as the anterior nasal flap, barbel, circumnarial fold and lower labial furrow. [10] Canal size typically corresponds to the body size of the animal but the number of ampullae remains the same. The canals of the ampullae of Lorenzini can be pored or non-pored.
