  abstract = {{T}he morphology of an individual can improve its ability to escape predators and ultimately its chances of survival. {S}icydiine fishes reproduce in rivers, and their larvae develop in the sea. {O}nce juveniles arrive in rivers, they face numerous predatory fish species. {S}ome juveniles can climb above the first waterfall where the abundance of predatory species is reduced. {F}or individuals that do not climb waterfalls, survival only depends upon their ability to avoid predation. {W}hile the factors that affect climbing performance of sicydiines have been extensively described, the information is scarce concerning their predator escape performance. {O}ur experimental study aimed to describe how the predation pressure imposed by three predatory fish species ({E}leotris klunzingerii, {K}uhlia rupestris, and {A}nguilla marmorata) affects the individual morphology of juveniles of two sicydiine species from {R}eunion {I}sland ({C}otylopus acutipinnis and {S}icyopterus lagocephalus). {I}ndividuals which survived predation had a more streamlined body and larger and/or longer pectoral fins for the two sicydiine species, whereas others morphological variables differed with the predator species. {B}ody form of individuals that survived predation also differed from the body form of individuals that climbed waterfalls. {T}he different prey's body forms under selection by the three predator species should be considered in further studies that could address the tradeoff in sicydiines between climbing waterfalls and escaping predation in the field. {F}or example, a careful description of the predator community would help to understand which predator(s) sicydiines juveniles need to escape in downstream reaches and how this particular predation pressure can select body forms.},
