How to identify a Grey Seal

- Grey Seal pups are born with pale coats and remain on shore during early nursing.
- Adults can dive repeatedly for fish and other marine prey.
- Colonies often gather on remote beaches, islands, or rocky coasts.
02
Adaptations and biological abilities
03
Why does Grey Seal behave this way?
- Thick blubber and a strong body support cold-water diving.
- Haul-out behavior lets seals rest, molt, breed, and recover on shore.
- A long muzzle and spotted coat distinguish Grey Seals from many other seals.
Grey Seals rest on land between feeding trips and may sleep both ashore and at sea. Their rhythm teaches that deep effort needs a protected return.

Why this diet?
06
Activity, rest, and lifespan
Grey Seals rest on land between feeding trips and may sleep both ashore and at sea. Their rhythm teaches that deep effort needs a protected return.
Grey Seals can live for decades, with females often living longer than males. Reserve deepens with age because repeated haul-outs, feeding grounds, and breeding sites become part of survival memory.
07
Grey Seal reproduction
Females give birth to a single pup on shore and nurse it with rich milk during a short intense period. Offspring make the return to land essential because the sea hunter must become a shore mother.
Males are much larger than females and develop heavier necks and more imposing heads. The Reserve lesson is shared, but male size adds competition while female endurance centers pup rearing.
08
Predators, threats, and defense
Orcas, large sharks, polar bears in some regions, and humans can threaten Grey Seals, while pups are especially vulnerable on shore. Haul-out choice matters.
