Clever whale sharks have figured out that fishing nets contain a lot of tasty fish. More importantly, they've figured out that they can suck those fish out of the net through holes in the net material.
The downside: When the sharks swim into fishing areas, looking for nets to suck, they can end up caught in the nets themselves. Conservation International took this video, showing why the sharks are hanging out around nets to begin with, as part of a series of videos documenting new net designs that can keep the fishies in and the whale sharks out.
