The description of the different mandibular morphologies can help to understand the different feeding guilds in this group. In this study, we examined the cranio\u2010mandibular myology of adult <jats:italic>Rostroraja velezi<\/jats:italic>, <jats:italic>Narcine entemedor<\/jats:italic>, and <jats:italic>Zapteryx exasperata<\/jats:italic>, three species of rays that coexist in the Southern Gulf of California, Mexico. This study described the muscles on the ventral and the dorsal surfaces for each species, identified the origins and insertions of these muscles, as well as the general characteristics of muscle morphology. There were 17 and 18 muscle bundles attached to the feeding apparatus, including five on the dorsal surface. Only the levator rostri, which elevates the rostrum during feeding, showed considerable differences in shape and size among species. The muscles of the adductor complex showed the greatest differences in size among the three species. <jats:italic>N. entemedor<\/jats:italic> presented the exclusive muscle X in the lower mandibular area and the extreme reduction of the coracohyoideus in the pharyngeal area derived from the absence of the basihyal cartilage. The information generated in our study supports the morphological specialization of electric rays (<jats:italic>N. entemedor<\/jats:italic>) for an almost exclusive suction feeding strategy.<\/jats:p>","DOI":"10.1002\/jmor.21547","type":"journal-article","created":{"date-parts":[[2022,12,19]],"date-time":"2022-12-19T07:50:24Z","timestamp":1671436224000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Comparative cranio\u2010mandibular myology of three species of Batoidea from the Southern Gulf of California, Mexico"],"prefix":"10.1002","volume":"284","author":[{"given":"Cristina","family":"Ram\u00edrez\u2010D\u00edaz","sequence":"first","affiliation":[{"name":"Instituto Polit\u00e9cnico Nacional Centro Interdisciplinario de Ciencias Marinas La Paz Baja California Sur M\u00e9xico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7559-585X","authenticated-orcid":false,"given":"Renato","family":"Pe\u00f1a","sequence":"additional","affiliation":[{"name":"Instituto Polit\u00e9cnico Nacional Centro Interdisciplinario de Ciencias Marinas La Paz Baja California Sur M\u00e9xico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9008-1910","authenticated-orcid":false,"given":"Rui","family":"Diogo","sequence":"additional","affiliation":[{"name":"Department of Anatomy Howard University College of Medicine Washington District of Columbia USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"V\u00edctor H.","family":"Cruz\u2010Escalona","sequence":"additional","affiliation":[{"name":"Instituto Polit\u00e9cnico Nacional Centro Interdisciplinario de Ciencias Marinas La Paz Baja California Sur M\u00e9xico"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,12,18]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ympev.2011.12.012"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.2460\/javma.2001.218.669"},{"key":"e_1_2_9_4_1","unstructured":"Cabrera P.(2017).H\u00e1bitos alimentarios de Narcine entemedor en la Bah\u00eda de La Paz M\u00e9xico.
