Morphology of Orestias ispi, an abundant pelagic species from Lake Titicaca (Peru/Bolivia). Note the protrusible mouth (b) evolved for suction feeding on zooplankton and the tightly interdigitating gill rakers (c) that help retain zooplankton. See Vaux et al. 1988. Ecology of the pelagic fishes of Lake Titicaca, Peru-Bolivia. Biotropica 20:220-229.
