Why do oceanic wanderers choose a single island home?
In short: Spinner dolphins are known for their acrobatic leaps across open oceans, yet a specific population in Brazil shows a surprising preference for a sheltered bay. This documentary explores their unique behavior and the threats facing their habitat.
While many spinner dolphins live in tropical open waters and may spend years without seeing land, the Noronha Spinners of Brazil exhibit distinct behavior. They visit the island of Fernando de Noronha almost daily, gathering in what is considered the world's most visited bay by dolphins.
The film captures their signature acrobatics—leaping more than 3 metres above the water and spinning up to 7 times—while investigating why these oceanic specialists seek out sheltered waters. It also highlights a research project aimed at conserving this population against the pressures of tourism and human-driven environmental changes.
