Grey Seals

What are they?

They are seals that roam

the UK seas. Grey seals are

protected by animal services.


What is their breeding season?

 During the pupping season, male grey seals also come ashore to mate. The largest males, usually more than 10 years old, compete for a position within groups of breeding females. They breed from December to September.


What are their measurements?

The large males weigh up to 400kg whilst the females reach 250kg at the most. Adult boys measure up to 1.95 m – 2.5m. Ladies measure 1.65m – 2.1m.


What do they eat?

Grey seals eat an extremely wide variety of fish, crustaceans and cephalopods with regional and seasonal variations. Sand eels or sand lances are the preferred prey in many areas. Seabirds are also occasionally eaten. Grey seals are known to dive regularly to about 30-70m while feeding.


How do grey seals hunt?

Grey seals hunt alone out at sea. Even blind seals can easily catch prey. They dive for just a few minutes, swallowing their prey whole underwater or bringing larger catches up to the surface, where they shake them into more manageable pieces. 


How do grey seals communicate?

Seals can also communicate through movements. Harbour seals slap the water with their bodies or flippers to show aggression. They make noises such as: howling, hooting, roaring and snarling. The pups make a crying noise.



What happens when seals interact with plastic?

 Seals in particular are affected by pollution because they do not migrate, but instead, live year-round in our region. After ingesting micro plastic seals can suffer for months or even years before they die.








All about seal pups!

A mother leaves its pup after the first month to finish growing and fend for themselves. Mothers do not teach pups to hunt, they learn on their own. Seal pups bite, there are two reasons why you should never go near a seal pup: they bite and spread nasty bacteria from their mouths!
