Research exposes that trumpetfish stealthily hunt by camouflaging themselves behind other fish like parrotfish, deceiving their victim, damselfish, in an unique survival method that may end up being more extensive due to coral reef degradation.An experiment on coral reefs offers the very first evidence that predators use other animals for motion camouflage to approach their prey without detection.A brand-new research study provides the first experimental proof that the trumpetfish, Aulostomus maculatus, can conceal itself by swimming closely behind another fish while hunting– and reduce the possibility of being detected by its prey.In this watching habits, the long, thin trumpetfish utilizes a non-threatening species of fish, such as parrotfish, as camouflage to get closer to its dinner.This is the just recognized example of one non-human animal utilizing another as a form of concealment.The research included hours of diving in the Caribbean Sea, pulling hand-painted design fish along a wire.The long thin trumpetfish utilizes a bigger, non-threatening species of fish, such as parrotfish, as camouflage to get closer to its dinner without being identified.
