Abstract

Despite the importance of Ancistrocheirus lesueurii in the diet of a wide variety of oceanic predators, many aspects of its biology are unknown. We report new observations on the reproductive system of the species and provide age estimates of one normal and two intersexual males based on the number of increments in the statoliths. The age of the examined mature males was estimated to be more than 2 years, increasing the maximum age known for males of the species. Female A. lesueurii have specific modified areas for spermatangia reception in the nuchal region. The morphology of the right hectocotylized ventral arm and the relatively large spermatophore are also described.
