Resumo: The externalization of internal organs in fish has been recorded over time in the scientific literature. Most of the records are related to the eversion or protrusion of the stomach and /or intestine, mainly due to barotrauma. However, a small portion of the records refer to several natural causes. The present study aimed to record the occurrence of a rare event of vaginal eversion in the spiny dwarf ray Psammobatis rutrum. On 06/15/2020 three specimens (2 females and 1 male) were captured as bycatch pair trawl in Barra de Santos SP, with an average depth of 27 meters. Among them, a female specimen presented a protrusion via the cloacal opening. Through necropsy, comparative evaluation and study of the reproductive pathways it was identified that the externalized organ was the vaginal wall. Although there are many records of externalization of Elasmobranchii organs, mainly related to the natural eversion behavior of the stomach and intestine, only one record of this type of event has been reported for the reproductive organ. It was not possible to identify the cause of vaginal eversion, but this event is associated with a pelvic prolapse, which may have been intensified by natural causes or due to capture.

La mayoría de los registros están relacionados con la eversión o protrusión del estómago y/o intestino, principalmente por barotrauma. Sin embargo, una pequeña parte de los registros se refiere a varias causas naturales. El presente estudio tuvo como objetivo registrar la ocurrencia de un evento raro de eversión vaginal en la raya enana espinosa Psammobatis rutrum. El 15/06/2020 tres ejemplares (2 hembras y 1 macho) fueron capturados como fauna acompañante de pesca en pareja en las cercanías del Barra de Santos SP, con una profundidad promedio de 27 metros. Entre ellos, un ejemplar femenino presentó una protuberancia a través de la abertura cloacal. Mediante necropsia, evaluación comparativa y estudio de las vías reproductivas se identificó que el órgano exteriorizado era la pared vaginal. Aunque existen muchos registros de externalización de órganos de Elasmobranchii, principalmente relacionados con el comportamiento natural de eversión del estómago e intestino, solo se ha reportado un registro de este tipo de evento para el órgano reproductor. No fue posible identificar la causa de la eversión vaginal, pero este evento se asocia con un cuadro de prolapso pélvico, que puede haberse intensificado por causas naturales o por captura.A externalização de órgãos internos em peixes tem sido registrada ao longo do tempo na literatura científica. Grande parte dos registros está relacionada à eversão ou protrusão do estômago e/ou intestino, devido principalmente ao barotrauma. Porém uma pequena parcela dos registros é referente a diversas causas naturais. O presente estudo teve como objetivo registrar a ocorrência de um raro evento de eversão vaginal na raia anã espinhosa Psammobatis rutrum. Em 15/06/2020 três exemplares (2 fêmeas e 1 macho) foram capturados como fauna acompanhante da pesca de parelha nas proximidades da Barra de Santos SP, com profundidade média de 27 metros. Dentre eles, uma exemplar fêmea apresentava uma protrusão via abertura cloacal. Através de necropsia, avaliação comparativa e estudo das vias reprodutivas foi identificado que o órgão externalizado era a parede vaginal. Embora existam muitos registros de externalização de órgãos de Elasmobranchii, principalmente relacionados ao comportamento natural de eversão do estômago e intestino, apenas um registro deste tipo de evento foi reportado para órgão reprodutivo. Não foi possível identificar a causa da eversão vaginal, porém tal evento está associado a um quadro de prolapso pélvico, que pode ter sido intensificado por causas naturais ou devido a captura.Research, Society and Development2021-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1682610.33448/rsd-v10i7.16826Research, Society and Development; Vol. 10 No. 7; e51410716826Research, Society and Development; Vol. 10 Núm. 7; e51410716826Research, Society and Development; v. 10 n. 7; e514107168262525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/16826/15067Copyright (c) 2021 Bruna Cabral Carneiro Batista; Helen Sadauskas-Henrique; Matheus Marcos Rotundohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBatista, Bruna Cabral Carneiro Sadauskas-Henrique, HelenRotundo, Matheus Marcos2021-07-18T21:07:03Zoai:ojs.pkp.sfu.ca:article/16826Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:37:16.645962Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
