Cobia following sharks?

Hey guys, I've been watching some videos of guys catching cobia, which are swimming alongside bull sharks.
Do the bull sharks not eat cobia? I'd figure if one was too close he'd get munched on.

There is always a complex interaction between predators and prey that ensures that most of the healthy individuals in a prey species survive. If you look at the way cobia follow large sharks, you'll notice that they hang out either along side of the shark or will trail it from just behind. In those locations they are pretty much invulnerable to attack by the shark, yet are able to prey on fish that the shark might miss. They also may be saving energy by drafting with the shark where the shark reduces water resistance.
You can be sure that if a large shark encounters a sick or injured cobia that isn't showing the proper behavior, it's curtains for the cobia.
