Foetal morphology enabled characterization of developmental stages, including one middle\u2010stage and two late\u2010stage pregnancies. External distension was absent in the middle\u2010stage case but detectable in late\u2010stage pregnancies, though not always evident in video imagery. These findings demonstrate that underwater ultrasonography is a feasible, non\u2010invasive approach to improve pregnancy detection and refine reproductive parameters in wild manta ray populations.\n                  <\/jats:p>","DOI":"10.1111\/jfb.70669","type":"journal-article","created":{"date-parts":[[2026,9,24]],"date-time":"2026-09-24T08:20:19Z","timestamp":1790238019000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Underwater ultrasonography confirms pregnancy and identifies developmental stages in free\u2010swimming oceanic manta rays (\n                    <i>Mobula birostris<\/i>\n                    )"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3632-8414","authenticated-orcid":false,"given":"Madalena Pereira","family":"Cabral","sequence":"first","affiliation":[{"name":"Cuidando los Mares de M\u00e9xico A.C  Ciudad de M\u00e9xico Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alisa L.","family":"Newton","sequence":"additional","affiliation":[{"name":"ZooQuatic Laboratory, LLC  Baltimore Maryland USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8476-7211","authenticated-orcid":false,"given":"Jessica H.","family":"Pate","sequence":"additional","affiliation":[{"name":"Marine Megafauna Foundation  West Palm Beach Florida USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0052-0140","authenticated-orcid":false,"given":"Tania","family":"Pelamatti","sequence":"additional","affiliation":[{"name":"Independent Researcher  Termoli Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,24]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1098\/rsos.250838"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/jfb.15423"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1095-8649.2010.02669.x"},{"key":"e_1_2_8_5_1","unstructured":"Marshall A.
