Here is an AMAZING and brave bit of assistance given to a whale shark from a diver. He cut away a piece of rope that must have been irritating that big guy for a long time, judging by the damage underneath it. Look how patient and gentle the whale shark was during the activity.
According to the website where I found this video, the whale shark actually tugged on the diver's hand to get his attention. Now THAT makes the diver doubly brave. Here is the link with more photos. ~Brian
