PALABRAS CLAVE: Molusco; Fissurellidae; Sistema reproductivo; Anatomia microscopica; Taxonomia.
The detailed anatomy of the reproductive system in the Fissurellidae, however, is subject to some controversy.
Relations between the reproductive and excretory systems of the Fissurellidae were controversial until now.
Unlike that of many other vetigastropod groups such as the Fissurellidae
, Solariellidae and Trochidae, it is difficult to prepare for SEM.
The volcano keyhole limpet Fissurella volcano (Reeve 1849) is a prosobranch gastropod of the family Fissurellidae. It is found from northern California through the Baja California Peninsula of Mexico, attaching to rocks of the tidal zone, where it feeds mainly on benthic microalgae, although it may also browse on macroalgal fronds (Hobday 1995).
A fissure, appearing on the anterior edge of the teleconch, will give rise to the keyhole (XIIc-KF), which characterizes the family Fissurellidae. Postlarvae are 470 [+ or -] 10 [micro]m long.
