Male reproductive traits of the marine snail Buccinanops deformis (King, 1832), (Gastropoda: Nassariidae): Size and age at maturity and sperm morphology
Size and age at sexual maturity in males was studied in Buccinanops deformis through analysis of gonadal tissue samples, secondary sexual characters and mating behavior in Golfo San Matías, Patagonia. Gonadal maturity occurred prior to the development of secondary sexual characters. Size at first go...
