Grey seals are the biggest land breeding mammal in the United Kingdom, but are superbly adapted for life in the sea. Adult gray seals have 2 layers of thick fur and a thick blubber layer of fat to keep them warm at sea.
Grey Seal pups have a white coat when born & for up to 3 weeks, then they moult into their adult coat. The gray seal mums feed their pups for 15 to 21 days with a rich milk that is 60% fat and the gray seal pups balloon out very quickly. After this weaning stage the gray seal mums leave their pups and the area. Grey seal pups leave too, as they must teach themselves to feed.
Life is hard for Grey Seal pups. About 30 to 50 percent of them die before their first birthday. Grey seal mums recognize their own pups calls and know exactly how their own pup smells.
The Cornwall Seal Group in south west England was set up to monitor the presence (or absence) of seals in a north coast colony. For more information, please see: cornwallsealgroup.co.uk
