The waters off Costa Calma host one of the highest recorded densities of pilot whales in the North Atlantic.
Twenty-three cetacean species frequent the submarine canyon that runs parallel to Fuerteventura's southeastern coast, where the ocean floor drops from two hundred metres to over two thousand within five nautical miles. This geological feature funnels nutrient-rich upwellings that sustain populations of short-finned pilot whales, bottlenose dolphins, and migrating fin whales — the latter passing through during spring and autumn on routes between Arctic feeding grounds and equatorial breeding zones.
The port's location at the mouth of the canyon offers direct access to feeding zones without the extended transit times required from northern embarkation points. Operators use purpose-built catamarans and rigid-hulled inflatables equipped with hydrophones, allowing passengers to track vocalizations before visual sightings. Morning departures between nine and noon align with peak cetacean activity, when calmer sea states improve spotting distances.
Short-finned pilot whales, misnamed as whales but classified as oceanic dolphins, maintain year-round residency in these waters. Matriarchal pods of twenty to forty individuals display complex social behaviours — coordinated dives to depths of five hundred metres, surface resting formations, and vocal exchanges that carry across open water. Bottlenose dolphins, smaller and more acrobatic, frequently bow-ride alongside vessels. Atlantic spotted dolphins appear in larger groups during summer months. Snorkeling extensions on certain tours allow underwater observation of subtropical fish species above volcanic reefs, though direct cetacean encounters while swimming remain rare and are restricted by Spanish marine protection protocols.
The Canary Islands were designated a Whale Heritage Site in 2021, recognising both the ecological significance of resident populations and the economic shift from historical whaling to conservation-focused tourism. Fuerteventura's arid landscape — visible as ochre cliffs and windswept dunes from offshore — contrasts sharply with the biological richness beneath the surface. Sightings are documented by onboard naturalists who contribute data to the Atlantic Cetacean Research Society, a monitoring network tracking population health and migration patterns across the archipelago.
