They provide an overview of the morphology of the brain and associated tissues located in the cranial cavity. Through anatomical comparisons between species, insights on the senses, the behavior, and the lifestyle can be gained. Although there are many studies dealing with mammal and bird endocasts, those performed on the brain endocasts of squamates are comparatively rare, thus limiting our understanding of their morphological variability and interpretations. Here, we provide the first comparative study of snake brain endocasts in order to bring new information about the morphology of these structures. Additionally, we test if the snake brain endocast encompasses a phylogenetic and\/or an ecological signal. For this purpose, the digital endocasts of 45 snake specimens, including a wide diversity in terms of phylogeny and ecology, were digitized using CT, and compared both qualitatively and quantitatively. Snake endocasts exhibit a great variability. The different methods performed from descriptive characters, linear measurements and the outline curves provided complementary information. All these methods have shown that the shape of the snake brain endocast contains, as in mammals and birds, a phylogenetic signal but also an ecological one. Although phylogenetically related taxa share several similarities between each other, the brain endocast morphology reflects some notable ecological trends: e.g. (i) fossorial species possess both reduced optic tectum and pituitary gland; (ii) both fossorial and marine species have cerebral hemispheres poorly developed laterally; (iii) cerebral hemispheres and optic tectum are more developed in arboreal and terrestrial species.<\/jats:p>","DOI":"10.1111\/joa.12692","type":"journal-article","created":{"date-parts":[[2017,9,28]],"date-time":"2017-09-28T15:55:05Z","timestamp":1506614105000},"page":"849-868","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["Comparative morphology of snake (Squamata) endocasts: evidence of phylogenetic and ecological signals"],"prefix":"10.1111","volume":"231","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7912-7607","authenticated-orcid":false,"given":"R\u00e9mi","family":"Allemand","sequence":"first","affiliation":[{"name":"Centre de Recherche sur la Pal\u00e9obiodiversit\u00e9 et les Pal\u00e9oenvironnements CR2P \u2010 UMR 7207 \u2010 CNRS MNHN UPMC Mus\u00e9um National d'Histoire Naturelle Sorbonne Universit\u00e9s Paris France"},{"name":"D\u00e9partement Adaptations du Vivant UMR 7179 \u2013 CNRS\/Mus\u00e9um National d'Histoire Naturelle Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Renaud","family":"Boistel","sequence":"additional","affiliation":[{"name":"IPHEP\u2010UMR CNRS 6046 UFR SFA Universit\u00e9 de Poitiers Poitiers France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gheylen","family":"Daghfous","sequence":"additional","affiliation":[{"name":"Groupe de Recherche sur le Syst\u00e8me Nerveux Central D\u00e9partement de Neurosciences Universit\u00e9 de Montr\u00e9al Montr\u00e9al QC Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zo\u00e9","family":"Blanchet","sequence":"additional","affiliation":[{"name":"D\u00e9partement Adaptations du Vivant UMR 7179 \u2013 CNRS\/Mus\u00e9um National d'Histoire Naturelle Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rapha\u00ebl","family":"Cornette","sequence":"additional","affiliation":[{"name":"Institut de Syst\u00e9matique, Evolution, Biodiversit\u00e9 ISYEB \u2013 UMR 7205 \u2013 CNRS MNHN UPMC EPHE Mus\u00e9um National d'Histoire Naturelle Sorbonne Universit\u00e9s Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nathalie","family":"Bardet","sequence":"additional","affiliation":[{"name":"Centre de Recherche sur la Pal\u00e9obiodiversit\u00e9 et les Pal\u00e9oenvironnements CR2P \u2010 UMR 7207 \u2010 CNRS MNHN UPMC Mus\u00e9um National d'Histoire Naturelle Sorbonne Universit\u00e9s Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peggy","family":"Vincent","sequence":"additional","affiliation":[{"name":"Centre de Recherche sur la Pal\u00e9obiodiversit\u00e9 et les Pal\u00e9oenvironnements CR2P \u2010 UMR 7207 \u2010 CNRS MNHN UPMC Mus\u00e9um National d'Histoire Naturelle Sorbonne Universit\u00e9s Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexandra","family":"Houssaye","sequence":"additional","affiliation":[{"name":"D\u00e9partement Adaptations du Vivant UMR 7179 \u2013 CNRS\/Mus\u00e9um National d'Histoire Naturelle Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,9,28]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/sysbio\/syu030"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/ar.22996"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1643\/0045-8511(2000)2000[0265:NHFMBI]2.0.CO;2"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/cne.20081"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1670\/111-02N"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1177\/159101990801400103"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/joa.12378"},{"key":"e_1_2_1_9_1","unstructured":"BalesTB(2014)Proliferation migration and survival of cells in the telencephalon of the ball python Python regius.
