A videographer documented a fin whale engaged in feeding behavior off the Pembrokeshire coast in Wales, capturing footage that shows the mammal’s expandable throat pleats taking in massive quantities of seawater and krill. The incident occurred while the videographer was fishing with a friend and using a drone to record marine life. The footage also shows the whale swimming alongside dolphins in the coastal waters.
Fin whales rank as the second-largest living organisms on Earth, behind only blue whales. These creatures can reach lengths of up to 24 meters and weigh as much as 70 tonnes. Despite their immense size, fin whales are notably elusive animals that spend most of their existence in the open ocean, typically surfacing only briefly before submerging. They inhabit oceans worldwide but prefer cooler water environments.
The videographer, who works in the oil refining industry but has developed expertise in marine videography, described the encounter as the result of fortunate timing. He explained that while operators attempt to maintain safe distances from whales during boat-based observation, wildlife can approach unpredictably. A marine ecology expert at Bangor University characterized the sighting as a rare occurrence, particularly given that fin whales conducting surface feeding in coastal waters is uncommon, as these animals typically migrate to other locations.
Fin whale migration patterns remain poorly understood by scientists, though research indicates these mammals show different movement behaviors compared to other baleen whale species. Studies have found fin whales concentrate in higher latitudes during warmer months and lower latitudes during colder periods, though this pattern varies. Fin whales maintain a relatively simple diet consisting primarily of krill, small schooling fish, and squid. Given the diminutive size of their typical prey, these whales must consume large quantities of food to meet their energy requirements, often spending several hours daily feeding and consuming up to 2,000 kilograms of food.
