Coastal seals

Breeding colonies of seals are usually located in the outer coastal zone, on islets and rocks, usually uninhabited by people. Animals gather in larger colonies in breeding and moulting periods.

  • Grey seal (Havert)
  • Harbour seal (steinkobbe)

Are vulnerable especially to fresh oil,  pups are especially vulnerable to surface oil that is brought to shore by adults, beached oil and near shore oil slicks. Seals are not known to avoid oil slicks.

Oil on the fur of pups may lead to loss of insulation properties of the coat. Adults of sone seal species are less dependent on their coat for insulation and are less vulnerable to oil contamination.
