Our work provides some of the first direct evidence that animal coloration is tuned to provide camouflage to prospective predators against a range of visual backgrounds, in a population of animals occurring over a small geographical range.Ĭamouflage coloration phenotype–environment predation.

Based on past work, this phenotype-environment matching is likely to be driven through ontogenetic changes rather than genetic adaptation. Helena Ascension Island Get Directions Business Description Volcano Club is located in Ascension Island. It is about 1,000 miles (1,600 km) from the coast of Africa and 1,400 miles (2,300 km) from the coast of South America. Individual sand fleas from a small, oceanic island (Ascension) matched the colour and luminance of their own beaches more closely than neighbouring beaches to a model of avian vision. Ascension Island is an isolated volcanic island, 756 south of the Equator in the South Atlantic Ocean. Here, we show that an intertidal crustacean, the sand flea (Hippa testudinaria), has coloration tuned to the different substrates on which it occurs when viewed by potential avian predators. However, while several studies have demonstrated phenotype-environment associations, few have directly shown that this confers an improvement in camouflage, particularly with respect to predator vision. A long-standing prediction is that individuals should have camouflage tuned to the visual backgrounds where they live. ![]() Camouflage is perhaps the most widespread anti-predator strategy in nature, found in numerous animal groups.
