Resumo: | The microscopic structure of the egg capsules of Atlantoraja cyclophora, a species endemic to the Atlantic region of South America, is presented in this paper. In a transverse section, the dorsal face of the egg case is 70 U in width, and is subdivided into four layers. Ventrally, the egg capsule wall is 60 U wide and composed of three layers. Both faces are covered by prickles which render the egg capsule surface striated to the naked eye. |

Em seção transversal, a face dorsal da cápsula ovígera tem uma largura de 70 U, e está subdividida em quatro camadas. Ventralmente, a parede da cápsula ovígera tem uma largura de 60 U e é conformada por três camadas. Ambas as faces acham-se cobertas por protuberâncias, que fazem com que a superfície da cápsula seja estriada ao olho nu.2011-11-01T15:53:20Z2011-11-01T15:53:20Z2005info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfODDONE, M.
