How long can narwhal live in captivity?

Narwhals are not commonly kept in captivity due to their specialized needs and challenging care requirements. When they are kept in controlled environments, their lifespan can be significantly reduced compared to their natural lifespan, which is typically around 30 to 40 years in the wild. There have been reports of narwhals living up to 20 years in captivity, but this varies widely and is generally considered less than optimal for their health and well-being.
