It’s all treat and no trick on this one. Giant trevally really do leap out of the water to reach their chosen prey, but reading that info in a book is not nearly as entertaining as seeing it acted out on film. GTs are voracious predators; depending on their location in the world’s oceans, they’ll eat anything from lobsters to crabs to shrimp to even turtles and dolphins—small ones, mind you.
As unique as breaching the surface to reach a bird is, another GT feeding strategy is even more strange than this one. GTs reportedly follow monk seals and reef sharks so closely that they act like unattached remoras. When the seal/shark stops to feed, the GT positions its mouth right under the host’s mouth, enjoying its meals right along with it.
