Reproductive strategies in anurans are attributed to combinations of physiological, morphological, and behavioral characteristics, always associated with microhabitat conditions. Cycloramphus boraceiensis is a frog species endemic from the Atlantic Forest of the Serra do Mar. Adults and offspring are found close to holes or crevice in rocks next to areas of waterfalls in fast streams. With unique characteristics of microhabitat use and lacking information concerning biology and reproductive behavior, C. boraceiensis is an excellent species for natural history studies. The main goal of the present study is the understanding of fundamental aspects of the biology and the reproductive behavior that are still unknow for this frog species from the family Cycloramphidae. Directly in the field, we recorded the microhabitat use and behaviors of the species. We recorded male-male competition events, including fights for reproductive resources. We also found three spawns throughout the study, all of them guarded by their respective guardian males, likely their parents. In the laboratory, we counted oocytes is adult females, also contributing to the understanding of the reproductive aspects of C. boraceiensis
