Abstract

This project aims to study the luminescent annelid Chaetopterus sp. and the ecological role of its light activity. This will allow for the improvement of its environment and habitat in the lab aquarium, which will increase its lifespan and allow for future experiments to be carried out related to how this organism's light production occurs. After experiments to determine the optimal feeding and abiotic conditions, such as temperature, light and substrate, it is expected that the captive life of Chaetopterus will improve. In this way, it will be possible to investigate the function of bioluminescence in this animal along with studying its reproduction using in vitro fertilization. Finally, photographic documentation of larvae and adults will be performed during this project, particularly in regards to their light emission.
