The persistent-predation strategy of the red lionfish (Pterois volitans).

ABSTRACT: The pursuit of prey is vital to the biology of a predator and many aspects of predatory behaviour are well-studied. However, it is unclear how a pursuit can be effective when the prey is faster than a non-cryptic predator. Using kinematic measurements, we considered the strategy of red lionfish (Pterois volitans) as they pursued a faster prey fish (Chromis viridis) under laboratory conditions. Despite swimming about half as fast as C. viridis, lionfish succeeded in capturing prey in 61% of our experiments. This successful pursuit behaviour was defined by three critical characteristics. First, lionfish targeted C. viridis with pure pursuit by adjusting their heading towards the prey's position and not the anticipated point of interception. Second, lionfish pursue
