It has been previously established that the Leopard Whipray, Himantura leoparda, consists of two genetically isolated, cryptic species, provisionally designated as 'Cluster 1' and 'Cluster 4' (Arlyza et al., Mol.

Two new species of tetraphyllidean cestodes inhabiting Himantura pacifica from the northwest coast of Costa Rica are apparently most closely related to species inhabiting Himantura schmardae from the Atlantic coast of Colombia. Acanthobothroides pacificus n. sp. differs from Acanthobothroides thorsoni, the only other species in the genus, primarily by having smaller lateral (98-123 microns rath...

Abstract Thirteen Chondrichthyes fish were caught in the current study, belonging to 12 genera and (6) orders representing (8) families from January 2018 December 2018. The Dasyatidae family represented highest number of species, by five species: Dasyatidae, Carcharhinidae, Hemiscylliidae, forming 74.74% total individuals. results relative abundance showed that three Brevitrygon walga, imbricat...
