One of the research developed here is related to Elasmobranchs reproduction, growth and ex-situ behavior. We succeeded in reproducing the Whitetip reef shark (Triaenodon obesus), an endangered species that reproduced for the first time under human care in Brazil. Research, Education and Conservation are the AquaRio pillars. That’s why we invest in scientific researches for the conservation of Elasmobranchs (sharks and rays), due to population decline in recent times. In partnership with REPROCON (Reproduction for Conservation), we develop semen collection and analysis of our sharks and rays. So, we can guarantee the maintenance of a healthy population under human care and the creation of a genetic bank for these species.
