The whale shark is so big that no other sharks even bother him, as he is far too large to be prey, upwards of 60ft long. While he doesn't consume other sharks, he eats literal tons of plankton while trolling the ocean for miles and miles, near constantly feeding, and using his large open mouth like a net.
So even though the white sharks, and bull sharks may have the killer instincts, and well documented, and aggressive, feeding habits, its safe to say that the whale shark, is the king of sharks ... so badass that he doesn't even have to be a badass to get respect.
Pretty sure that sums up the 'baddest shark in the ocean' thread ... the mods can lock and close now.
