Introduction. The visceral cavity of teleostean fishes contains the kidneys, digestive tube and annexed glands, gas bladder, gonads, and spleen. Objective: To analyze and describe the anatomic relationships of the organs of the visceral cavity of the Mexican mojarra, Eugerres mexicanus. Methods: By means of dissections, we analyzed, described and illustrated the splanchnology of the visceral cavity of 10 adult specimens from the State of Chiapas, Mexico. Results: The visceral cavity is delimited by the precaudal vertebrae, the scapular and pelvic girdles, the pleural ribs, the first anal pterygiophore and several myotomes. Both kidneys, with extraperitoneal character are partially fused each other, and contact the neurocranium, the precaudal vertebrae, and the gas bladder. The digestive tube does not present a stomach nor pyloric caeca, and it is 1.3 the standard length of the fish. The liver has two short right lobes. Both ovaries and testes are wide and reach the liver. The spleen is ovoid and is located on the left side of the duodenum. The gas bladder has two anterior lobes, its posterior end is in direct contact with the floor of the visceral cavity, and contain the urinary bladder. Discussion: The organization of the organs in the visceral cavity is in the anatomical pattern of the teleostean fishes, however, the organ that shows the highest number of special characters is the gas bladder, which as in other species of Eugerres is large and shows two notable anterior lobes, reinforced by epipleural ribs. Compared with other species of Eugerres, the Mexican mojarra shows, as exclusive characters: a) the union of the posterior end of the gas bladder with the floor of the visceral cavity, and, b) the location of the urinary bladder within the gas bladder. |

Objetivo: Analizar y describir las relaciones topográficas de los órganos de la cavidad visceral de la “mojarra mexicana” Eugerres mexicanus. Metodología: Mediante disecciones se analizó y describió la esplacnología de la cavidad visceral de 10 ejemplares adultos recolectados en el estado de Chiapas, México. Resultados: La cavidad visceral, está delimitada por las vértebras precaudales, las cinturas, las costillas pleurales, el primer pterigióforo anal y varios miotomos. Los riñones, los cuales son extraperitoneales, están parcialmente fusionados entre sí. El sistema digestivo carece de estómago y ciegos pilóricos y su longitud corresponde a 1.3 la longitud patrón. El hígado tiene dos lóbulos derechos. Las gónadas maduras son amplias. La vejiga gaseosa desarrolla dos lóbulos anteriores y su extremo posterior se une al piso de la cavidad visceral, e incluye a la vejiga urinaria. Discusión: La organización de la cavidad visceral y sus órganos corresponde al patrón morfológico de los peces teleósteos, siendo la vejiga gaseosa el órgano que muestra el mayor número de caracteres especiales, como los lóbulos anteriores, la unión de su extremo inferior al piso de la cavidad visceral y la ubicación de la vejiga urinaria en su interior. Estos dos últimos caracteres la distinguen de otras especies del género Eugerres.Universidad de Costa Rica2020-03-31info:eu-repo/semantics/publishedVersionArticleartículo originalhttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articleapplication/pdftext/htmlhttps://revistas.ucr.ac.cr/index.php/rbt/article/view/3854810.15517/rbt.v68i1.38548Revista de Biología Tropical; Vol. 68 No. 1 (2020): Revista de Biología Tropical (Int.
