  abstract = {{T}his study explores the relationship between morphology and diet in four {A}ndean killifishes ({O}restias) from {L}ake {T}iticaca that are known to differ in habitat use. {S}pecies that fed preferentially on amphipods ({O}restias albus) or molluscs ({O}restias luteus) separated in multivariate space from other species that feed on cladocera and algae ({O}restias agassii and {O}restias jussiei). {G}enerally, specimens feeding on cladocera were characterized by a short, blunt nose with a small mouth; whereas, specimens feeding on amphipods exhibited a long snout with a large mouth. {S}pecimens including molluscs in their diet tended to have a larger posterior part of the head and the larger opercles than others; while the occurrence of substratum in gut content was generally related to a short but deep head. {T}he present analysis suggests that the littoral {O}. jussiei has an intermediate phenotype and diet between the pelagic ({O}. agassii) and benthic ({O}. albus and {O}. luteus) species. {R}esults suggest that resource partitioning was occurring and that several morphological traits relate to characteristics of the diet, and it is inferred that the benthic, the pelagic and the littoral zones in the lake host different prey communities constituting distinct adaptive landscapes.},
