A newborn blacktip reef shark, which is listed as a vulnerable species, swims at night in Maya Bay at the Phi Phi Island National Park, on Phi Phi Leh Island, Krabi province, Thailand, February 24, 2023. Blacktips, named after the distinctive black colouring on their dorsal fins and tails, roam the Andaman Sea and other tropical regions in decreasing numbers due to overfishing, according to the International Union for Conservation of Nature.
