Ladoga Ringed Seal

Pusa hispida ladogensis

Also known as Ladoga Seal, Lake Ladoga Seal

Ladoga ringed seals are small, dark freshwater seals characterized by pale ring patterns scattered across their dark coats. They spend winters constructing snow lairs over breathing holes in the ice sheet of Lake Ladoga, where mothers nurse single white-coated pups. As spring thaws the lake, adults gather on rocky islets and floating ice floes to molt and bask in the sun.

Why interaction risk is low: Wild seals may bite if cornered or handled; observe from a safe distance on land or water.
What to notice: Look for a small, dark seal with pale ring markings swimming or resting in Lake Ladoga.
Support conservation: Keep at least 100 meters away on the water and avoid approaching winter snow lairs on the ice.

Responsible observation

Shoreline Watching: Use binoculars or a long lens to view seals without disrupting their rest.
Ice Precautions: Avoid approaching snow mounds or ice ridges that may conceal breeding lairs.
Boating Distance: Maintain slow speeds and stay at least 100 meters away from haul-out sites.
