Carangidae

The family Carangidae contains 146 species in 30 genera (fishbase) and is widely distributed in the Atlantic, Pacific and Indian oceans. They are nearly all silver, openwater predators often seen congregating in schools over and near coral reefs. The largest member of the family - the amberjack - can reach nearly 2m in length. Many members of the family have the ability to change color rapidly from silver to black and back again. The reasons for this color change are unknown but may be to signal an attacking intent, or to indicate sexual receptivity.

Some carangids will shadow wrasses, hanging around while the wrasse overturns rocks and feeding on fleeing food items. In the fabulous BBC Planet Earth episode Shallow Seas, dozens of sea snakes are seen joining carangids (and goatfish) and then hunting in tandem.

When I was staying at Kri Eco in Raja Ampat, West Papua there used to be a juvenile black tip reef shark (perhaps a metre in length) that cruised up and down the house reef in the shallows. One morning I heard an enormous spash and hurried out to see what had caused the commotion. I missed the attack but one of the dive masters told me that a giant trevally had eaten the black tip. Quite a feat - and I never saw the black tip again so believe the story.
