A rare grey seal (Halichoerus grypus) has been spotted on the beaches of Doñana National Park, marking the first sighting of this species in three years. Typically found in the cold waters of Northern Europe, the seal’s presence has surprised both biologists and nature enthusiasts.
Experts from Doñana National Park report that the seal has been swimming along the coast of Huelva province since December. Recent sightings have occurred at Matalascañas and within the national park’s beaches.
Monitoring and health assessment
The Marine Environment team at Doñana National Park is closely monitoring the animal. According to experts, the seal appears healthy, showing no signs of stress, injury, or malnutrition. At present, no intervention is required.
Grey seal sightings in southern Spain are extremely rare, as their natural habitat is typically in the cold waters of the north-western Atlantic, ranging from North America to the UK and Scandinavia.
Characteristics of the grey seal
Grey seals are among the largest seal species in the North Atlantic. Males can reach 2.7 metres in length and weigh up to 400 kilograms, while females are generally smaller. Their fur patterns range from light grey with dark spots to nearly solid dark coats.
Once heavily hunted, grey seals are now protected in many regions, though they still face threats from overfishing and plastic pollution. Conservation efforts have contributed to population recoveries in some areas.
A rare visitor to Doñana
The last recorded sighting of a grey seal in Doñana occurred three years ago. The reasons for its reappearance remain unclear.
Doñana National Park is one of Spain’s most significant protected areas, known for its rich biodiversity. While it serves as a refuge for birds and other wildlife, marine mammal sightings—especially of seals—are highly unusual.
