Underwater Trumpetfish: Trumpetfish inhabit coral reefs and seagrass beds worldwide. They consume shrimp. These stealthy hunters have 20-inch bodies and prominent snouts.
A Current Biology study shows that trumpetfish can hide behind larger, friendlier fish. This ingenious move makes trumpetfish more intriguing. Scientists wonder if other animals lie to catch prey.
Groupers and moray eels collaborate to locate food in coral reefs. When following larger fish, the trumpetfish appears to care about itself.
The trumpetfish has more tricks. It can change hues to resemble sticks, seaweed, or its environment. Hanging vertically in the water, it can swoop down on unsuspecting victims. One favorite way is hiding behind an innocuous fish like a parrotfish until it gets close enough to strike.
Sam Matchette, a University of Cambridge behavioral biologist, and study co-author, said this behavior has been observed for decades and written about in guidebooks, dive blogs, and a few research articles.

Shooting waterfowl has always been the same. “Stalking horses,” usually horses or animals, allowed hunters to creep up on ducks without startling them. Shooters still utilize this strategy, but they now use blinds and cutouts.
Dr. Matchette connected the two methods after discovering trumpetfish did something similar. His team experimented to investigate this similarity. They hung 3D-printed trumpetfish and parrotfish from a wire system near a coral reef in Curacao to observe damselfish interactions. The film captured events.
Damselfish approached the trumpetfish model as it crossed the wire but fled because they thought it was a threat. The parrotfish model was examined without alarm. The damselfish didn’t mind the trumpetfish riding the parrotfish model, either.
Dr. Luiz Rocha, head of ichthyology at the California Academy of Sciences, claimed this idea worked great. He felt many creatures might use it. Dr. Matchette concurred and predicted more occurrences of this conduct.
If climate change destroyed coral reefs, he thought stalking horses might be utilized more. Reef predators may hide among more giant corals as they perish. This may evolve.

How rare is a trumpet fish?
Trumpetfish can be found in shallow waters all across the Caribbean, from the Florida coast to the West Indies, along the Gulf of Mexico, the Yucatan Peninsula, and western Central America down to northern Brazil. They are quite abundant in these areas.
Where are trumpetfish found?
The trumpetfish can be found in the western Atlantic Ocean, ranging from southern Florida and Bermuda to the northern coast of South America. In the eastern Atlantic, you’ll spot this species off St. Paul’s Rocks.
What are some interesting facts about trumpetfish?
The trumpetfish has a body adorned with tiny scales, a line of spines along its back that can be raised for protection, and a short barbel on its chin. These elongated creatures can grow up to 80 cm (31 inches) in length. Known for preying on small fish and crustaceans, trumpetfishes are frequently found patrolling the reefs.
What are the different types of trumpet fish?
Three types of trumpetfish exist: the trumpetfish (Aulostomus maculatus) and the Atlantic trumpetfish (Aulostomus strigosus) in the Atlantic, and the Chinese trumpetfish (Aulostomus chinesis) in the Indo-Pacific.
