The boat slips away from Lisbon’s ribbed quay as the city blurs into a band of pastel buildings and the 25 de Abril Bridge climbs the skyline. The Tagus breathes under the hull and opens its shoulder to the Atlantic; gulls wheel and the water dares the bow forward. Onboard, a marine biologist scans the horizon, binoculars ready for the first flick of dorsal fin.
