My research brought me to investigate possible shark migrations between regional islands. In that way, I took part of an expedition in Tetiaroa, a small atoll located at about 50 km from Tahiti and Moorea (the only one atoll of the Society Archipel where only one family is living). This expedition was organized by the environmental association “Te mana o te moana” for sea turtle’s nest monitoring in French Polynesia.
I took part of the expedition in order to sample both sicklefin lemon sharks (Negaprion acutidens) and blackfin reef sharks (Carcharhinus melanopterus) for genetic analysis to compare relatedness with shark populations of Moorea. I sample both adults and juveniles. Tetiaroa has many nursery grounds were juvenile sharks grow inside the lagoon.
