The biological boundary where terrestrial giants meet the salt of the sea
In short: Explore the Bissagos Islands, a unique archipelago in Guinea-Bissau where wildlife thrives by crossing extreme environmental boundaries. This documentary follows biologist Raúl León as he tracks species that navigate the delicate transition between land and ocean.
The Bissagos Islands serve as a laboratory for survival at the intersection of mangroves, savannahs, forests, and tidal zones. The footage highlights remarkable adaptations: mudskippers traversing exposed mud, frogs enduring months of heat by sealing themselves off, and hippos migrating toward saltwater as seasonal lagoons dry up.
Beyond these hardy survivors, the expedition documents nesting green turtles, newly recorded reptiles, and giant invertebrates. By observing these animals, the film reveals the complex ecological mechanisms that allow life to persist in such a diverse and demanding landscape.
