Accessory glands and their ducts in the reproductive system of the male toadfish,Opsanus tau

  • Roger A. Hoffman


The accessory genital glands ofOpsanus tau are large fan-shaped organs lying in the posterior region of the abdominal cavity. Four distinct parts on each side can be recognized grossly and microscopically by virtue of morphology, color, secretion granules, and vascularity. All four parts have separate collecting ducts which drain into the paired spermatic ducts as they course posteriorly to exit into the cloaca via a grooved genital papilla. Seasonal changes in the gross and microscopic anatomy of the accessory glands are described.
