The database was implemented from several sources available on the Internet: Catalogue of Life, Genbank/NCBI, Global Biodiversity Information Facility, IUCN Red List and Wikipedia. </span></span><span style="font-size: small;"><span lang="en-US">Data were obtained for 308 valid reef fish species, included in 12 orders, 56 families and 165 genera. The complete database is available for consultation at http://coralfish.scienceontheweb.net.</span></span></p> Mauro José Cavalcanti Paulo Roberto Duarte Lopes, Prof. ##submission.copyrightStatement## https://creativecommons.org/licenses/by-nc/4.0/ 2025-09-26 2025-09-26 5 1/2 1 5 http://tropicaldiversity.org/site/index.php/td/article/view/23 <p class="western" style="line-height: 100%; margin-top: 0.21cm; margin-bottom: 0cm;" align="justify"><span style="color: #000000;"><span style="font-size: small;"><span lang="pt-BR"><em><span style="font-weight: normal;">Diplectrum formosum </span></em></span></span></span><span style="color: #000000;"><span style="font-size: small;"><span lang="pt-BR"><span style="font-weight: normal;">e </span></span></span></span><span style="color: #000000;"><span style="font-size: small;"><span lang="pt-BR"><em><span style="font-weight: normal;">D. radiale</span></em></span></span></span><span style="color: #000000;"><span style="font-size: small;"><span lang="pt-BR"><span style="font-weight: normal;"> são espécies de peixes serranídeos de pequeno porte que ocorrem nas águas do Atlântico Ocidental.

As coordenadas dos marcos foram alinhadas pelo método generalizado dos mínimos quadrados, sendo submetidas à análise de deformações. A matriz de escores das deformações parciais foi utilizada na análise de funções discriminantes. A diferença entre as espécies, estimada com base em 1.000 permutações aleatórias dos exemplares, foi altamente significativa (Hotelling T</span></span></span></span><span style="color: #000000;">^{<span style="font-size: small;"><span lang="pt-BR"><span style="font-weight: normal;">2</span></span></span>}</span><span style="color: #000000;"><span style="font-size: small;"><span lang="pt-BR"><span style="font-weight: normal;">, p &lt; 0,05).
