• Abstract

  Due to their simplicity, planarian eyes depict the anatomy of the metazoan eye prototype. However, we postulate that eyes of planarians are more variable and complex than generally assumed. Sensory systems have diversified as a result of evolutionary pressures found in the distinct habitats that planarians occupy, including fresh water, terrestrial, caves, and oceanic systems. Among the T…

• Abstract

  Sexual selection has a crucial role in the evolution of reproductive traits. Males use several strategies to ensure fertilization, but females also play a major role in pre and postcopulatory processes. Cephalopods transfer sperm packed within spermatophores, and in some cases females bear specialized organs for sperm storage (i.e., seminal receptacles). However, the morphology of these o…

• Abstract

  Species of the genus Aplysia are found on rock shore regions and represent an important trophic chain in the sea environment. They are hermaphrodites and their biological life cycle lasts nearly one year; the population abundance is associated with the algae. The species Aplysia brasiliana is richly used in studies related on neuroscience and genetics, however little is known about their …

• Abstract

  Adaptations to dark environments lead to a convergent loss of eyes in different phyla, resulted by changes in classic eye development genes expression. Planarians are an interesting group to study eye development because adult animals can regenerate their eyes within a week after decapitation, recruiting classic eye development genes orthologues. During my PhD project I found that the obl…

• Abstract

  Sexual selection has a crucial role in the evolution of reproductive traits. Males use several strategies to ensure fertilization, but females also play a major role in pre and post-copulatory processes. Cephalopods transfer sperm packed within spermatophores, and in some cases females bear specialized organs for sperm storage (i.e., seminal receptacles). However, the morphology of these …

• Abstract

  Species of the genus Aplysia are gastropod molluscs opisthobranch belonging to the family Aplysiidae. They live in temperate and tropical seas of the all world, the genus Aplysia is composed of approximately 30 species differentiated by size, color, geographical distribution, morphology and physiology. Despite the extensive study of the Aplysia brasiliana, few of these studies present a f…
