![]() This change in behaviour may be a tactic to reduce competition from other archerfish.Īrcherfish are capable of rapidly determining where and when a shot prey item will land any archerfish that can see a shot being made can work out where the prey will land – as a result they may be able to get the prey item before the fish that made the effort to shoot. The research, led by scientists from the Centre for Social Learning and Cognitive Evolution at St Andrews, in collaboration with Bayreuth University, Germany, found that when archerfish are observed by fish in a neighbouring tank, the shooting fish more frequently aim and reposition before making a shot. Archerfish hunt prey by lining up their body and focusing on their target before shooting them with jets of water On those occasions the fish will reposition before aiming again and making a shot from a different position or angle. When shooting, archerfish need to ‘aim’, lining up their body with and focusing on their target, but sometimes they will aim without shooting. The new study, published in Animal Behaviour (Friday 15 June), has discovered that archerfish take longer to make a shot when they are observed by another fish. ![]() Archerfish, famed for their ability to hunt prey by shooting them down with jets of water, seem to suffer social inhibition, according to new research led by the University of St Andrews. ![]()
