Seals live almost everywhere in the world – from the icy waters of the Arctic and Antarctic to the warm coasts of Africa and South America. There are even seals in freshwater lakes – such as the Baikal seal in Lake Baikal (Russia). Some species tend to be solitary, whilst others live in large colonies. They come ashore or onto sea ice to rest and give birth. There are over 30 different species of seal around the world. Some of them are pictured here.

Only three families – but so many differences

Seals are divided into three families, classified mainly by their ears and the way they move on land and in the water. But there is so much more to them:

Identifying earless seals

(using the harbour seal as an example)

Social behaviour: live as solitary individuals or in small groups

Moving on land: by galumphing like a caterpillar using abdominal and back muscles

  • Ears: only ear holes
  • Propulsion in water: hind flippers
  • Fore flippers: short

Identifying eared seals

(using the California sea lion as an example)

Social behaviour: live in colonies

Moving on land: by walking on all four flippers

  • Ears: visible ear flaps
  • Fore flippers: long
  • Propulsion in water: fore flippers

Identifying walruses

Social behaviour: spend most of their time in colonies

Moving on land: by using all four flippers 

  • Fore flippers: short
  • Propulsion in water: hind flippers
  • Ears: only ear holes

Males and females have tusks that grow throughout their lives


Seals in the North Sea and the Baltic Sea

Two seal species live along Germany’s coasts. The common seal is mainly found in the North Sea, whilst the grey seal is also found in the Baltic Sea. With a bit of luck, they can be spotted on sandbanks or on quiet beaches.
