Comment on “Open-ocean fish reveal an omnidirectional solution to camouflage in polarized environments”
Abstract
Brady et al . (Reports, 20 November 2015, p. 965) claimed that the silvery sides of certain fish are cryptic when viewed by animals with polarization sensitivity, which they termed “polarocrypsis.” After examining their evidence, we find this claim to be unsupported due to (i) pseudoreplication, (ii) confounding polarization contrast with intensity contrast, and (iii) measurements taken at very shallow depths.
