Imperfect transparency and camouflage in glass frogs [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2020 Camouflage patterns prevent detection and/or recognition by matching the background, disrupting edges, or mimicking particular background features. In variable habitats, however, a single pattern cannot match all available sites all of the time, and efficacy may therefore be reduced.
