Resumo:  Predators are known to modify hunting tactics in response to local conditions to exploit prey of different species, densities or position within habitat patches. I describe three unusual prey hunting tactics used by trumpetfish (Aulostomus maculatus) distributed in midwater above reefs off Bonaire, Netherlands Antilles, in the southern Caribbean Sea. Hunting behaviors were focused on dense feeding aggregations of brown chromis (Chromis multilineata) and were categorized as: (1) slow horizontal following, (2) vertical hovering or drift, and (3) diagonal cross encounters where trumpetfish descended diagonally through the water while adjusting trajectory to encounter target prey. Understanding variation in predator behavior and ambit, in this case vertical ambit, adds to our knowledge of how predators adapt to unique local opportunities to exploit prey.
