Seeing Beyond Violet: UV Cones Guide High-Resolution Prey-Capture Behavior in Fish.

How can fish see tiny underwater prey invisible to human eyes? In this issue of Neuron, Yoshimatsu et al. (2020) show that ultraviolet light and a rich set of fine-tuned anatomical and neural specializations originating in ultraviolet-sensitive cones underlie high-resolution prey-capture behavior in larval zebrafish.
