<p>Data from Binning & Roche 2015 (Ecology: 10.1890/14-0426.1)</p> <p>This study evaluated the generality of intraspecific phenotypic divergence in widespread coral reef fishes by exploring patterns of fin shape divergence in 12 common species from three families of pectoral fin swimming (labriform) fishes on the Great Barrier Reef. This study was conducted between March 2010 and August 2013 at sites around Lizard Island, on the northern Great Barrier Reef, Australia. Three sites located on reef crest habitats (2- 4 m depth) were chosen on the windward (wave exposed) and three sites on the leeward (sheltered) side of the island. In addition, two sites each on the reef slope (8 -10 m depth), crest (2 – 4 m depth) and back lagoon (1 – 2 m depth) were chosen on the windward side of the island. Fishes were collected with hand spears or barrier nets. Fish total length was measured with a ruler, and fin AR was calculated as the length of the leading edge squared divided by the total fin area. The abundance of adults fishes from the 12 species was recorded at all study sites by SCUBA divers using underwater belt transects (50 × 4 m). All adult individuals (displaying adult coloration and/or > 5 cm total length) were counted for each species in four replicate transects at each site covering 800 m2 of habitat per site. Please see Binning & Roche 2015 (10.1890/14-0426.1) for more detailed description of the methods.</p>
