Trumpetfish plays ‘hide-and-seek’ to hunt prey
- 10 months ago
Scientists have discovered that predatory trumpetfish play ‘hide and seek’ by lurking behind other, non-threatening species to sneak up on unsuspecting prey.
In this behaviour, known as shadowing, the trumpetfish uses a non-threatening species of fish, such as parrotfish, as camouflage to get closer to its dinner.
The trumpetfish’s camouflage tactics are the only known example of one non-human animal using another as a form of concealment.
“When a trumpetfish swims closely alongside another species of fish, it’s either hidden from its prey entirely, or seen but not recognised as a predator because the shape is different,” said Dr Sam Matchette, a researcher in the University of Cambridge’s Department of Zoology.
