Testicular histology of Mustelus schmitti springer, 1939 (Elasmobranchii, triakidae)

Abstract

Mustelus schmitti presenta unos testiculos de desarrollo diametrico en la que espermatocistos forma redonda muestran una disposición zonal. Cada zona tiene espermatocistos que contienen células germinales en una sola fase de desarrollo. Los especímenes adultos mostraron seis etapas diferentes que van desde espermatogonias a espermatozoides maduros. Las mismas etapas morfológicas se encuentran en los animales jóvenes, mientras que algunas etapas adultas se han encontrado en animales inmaduros entre las espermatogonias primarias o secundarias. Etapas similares en el desarrollo espermático se encontraron las descritas para M. manazo, M. griseus y otros elasmobranquios

The testicles of Mustelus schimitti from a temperate estuary in the South Western Atlantic have a diametric development in which round-shaped spermatocysts show a zonal arrangement. Each zone had spermatocysts containing germ cells in a single development phase. Adult specimens showed six different stages from spermatogonia to mature sperm. The same morphological stages were found in young animals, while some adult stages have been found in immature animals among the spermatogonia, whether primary or secondary. Spermatic stages were found in similar sequences as described for M. manazo, M. griseus and other elasmobranchs.
