The seals

Les phoques sont visibles à Berck tous les jours, en toute saison, à marée basse...

A long time ago set colonies of seals in the Baie d'Authie. A proof of it, is a sketch of Francis Tattegrain, dates back 1890.

Nowadays you can see up to 100 seals. Two species can be observed in Berck-sur-Mer grey seal and common seal.

It measures between 1,5 and 1,8 metres in length. The male weights approximately 110kg and the female about 80kg.

Grey seals: its muzzle is an extension of its forehead; its nostrils are parallel and it has a light mottled coat. It is twice the size of the common seal measuring between 1,95 meters. The male weights about 250kg and the female around 150kg.
