While cave environments are well known to promote regressive traits in fish such as eye and pigment loss, their influence on overall body form remains poorly understood. Here, we examine patterns of body shape variation in cave\u2010dwelling and surface\u2010dwelling trichomycterid catfishes from northeastern Colombia to assess whether consistent associations exist between habitat type and morphology. Using geometric morphometric analyses, we quantified differences in body shape among species inhabiting subterranean and surface environments. Our results reveal significant habitat\u2010associated differentiation in body shape along the main axes of morphological variation, despite some overlap indicating that habitat does not fully predict morphological variation. Cave\u2010dwelling species exhibit more elongated and fusiform body shapes, whereas surface\u2010dwelling species tend to have deeper and more robust morphologies. These patterns are consistent with differences in habitat\u2010associated ecological conditions, although no direct functional or performance data were evaluated. The recurrence of similar body shapes among species from different clades occupying comparable habitats is consistent with repeated morphological responses to shared ecological constraints.<\/jats:p>","DOI":"10.1002\/jmor.70166","type":"journal-article","created":{"date-parts":[[2026,9,4]],"date-time":"2026-09-04T10:37:51Z","timestamp":1788518271000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Recurrent Body Shape Patterns in Cave\u2010 and Surface\u2010Dwelling Trichomycterid Catfishes"],"prefix":"10.1002","volume":"287","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0959-7072","authenticated-orcid":false,"given":"Nelson","family":"Falc\u00f3n\u2010Espitia","sequence":"first","affiliation":[{"name":"Laboratorio de Biolog\u00eda Evolutiva de Vertebrados, Departamento de Ciencias Biol\u00f3gicas Universidad de Los Andes Bogot\u00e1 Colombia"},{"name":"Grupo de Morfolog\u00eda y Ecolog\u00eda Evolutiva, Instituto de Ciencias Naturales Universidad Nacional de Colombia Sede Bogot\u00e1 Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4530-2478","authenticated-orcid":false,"given":"Carlos Daniel","family":"Cadena","sequence":"additional","affiliation":[{"name":"Laboratorio de Biolog\u00eda Evolutiva de Vertebrados, Departamento de Ciencias Biol\u00f3gicas Universidad de Los Andes Bogot\u00e1 Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,4]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2148-10-216"},{"key":"e_1_2_10_3_1","first-page":"337","volume-title":"Origin and Phylogenetic Interrelationships of Teleosts","author":"Adriaens D.","year":"2010"},{"key":"e_1_2_10_4_1","volume-title":"Gui\u0301a pra\u0301ctica de morfometri\u0301a geome\u0301trica: aplicaciones en la ictiologi\u0301a","author":"Aguirre W.","year":"2018"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1086\/285398"},{"key":"e_1_2_10_6_1","first-page":"73","article-title":"Measurement Error in Geometric Morphometrics: Empirical Strategies to Assess and Reduce Its Impact on Measures of Shape","volume":"44","author":"Arnqvist G.","year":"1998","journal-title":"Acta Zoologica Academiae Scientiarum Hungaricae"},{"key":"e_1_2_10_7_1","first-page":"395","volume-title":"Vertebrates in the Tropics: Proceedings of the International Symposium on Vertebrate Biogeography and Systematics in the Tropics","author":"Arratia G.","year":"1990"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1098\/rsos.220713"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.4025\/actascibiolsci.v27i4.1271"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.18257\/raccefyn.35(135).2011.2503"},{"key":"e_1_2_10_11_1","first-page":"49","article-title":"Trichomycterus Santanderensis: A New Species of Troglomorphic Catfish","volume":"55","author":"Castellanos\u2010Morales C.","year":"2007","journal-title":"Zootaxa"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1590\/S1679-62252008000300003"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1098\/rspb.2022.1641"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.3897\/zookeys.695.13360"},{"key":"e_1_2_10_15_1","first-page":"1","article-title":"Convergence of Undulatory Swimming Kinematics Across a Diversity of Fishes","volume":"118","author":"Di Santo V.","year":"2021","journal-title":"Proceedings of the National Academy of Sciences of the United States of America"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/jfb.14286"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1098\/rspb.2007.1169"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.1093\/icb\/icz026"},{"key":"e_1_2_10_19_1","doi-asserted-by":"publisher","DOI":"10.1111\/zsc.12475"},{"key":"e_1_2_10_20_1","doi-asserted-by":"publisher","DOI":"10.1093\/zoolinnean\/zlaa155"},{"key":"e_1_2_10_21_1","unstructured":"Fricke R.
