Long, thin, tubular fish that hunt by stealth rather than speed: the trumpetfish, which hangs among gorgonians, and the cornetfish, which hovers over open ground with a whip-like filament trailing off the tail.
The trumpetfish's method is to be somewhere else's outline. It hangs vertically head-down among sea whips and gorgonians, and it shadows larger fish - swimming alongside a parrotfish or a grouper - to get within range of prey that has already decided the larger fish is not a threat. It occurs in brown, blue-grey and bright yellow forms on the same reef.
The cornetfish is longer, thinner and out over sand and seagrass rather than in structure, and the filament off the tail is what identifies it at a distance. Both feed by getting close and then expanding the mouth suddenly, which pulls the prey in with the water.
Both are hard to photograph well for the same reason: the fish is a metre long and a few centimetres deep, so it either fills the frame end to end or reads as a stick. Shooting along the body rather than across it is usually the answer.
Every one has a page. They are shown as a list rather than as pictures because nothing has been photographed or logged for them yet, and a species with nothing behind it should not sit in front of one that has.
