Common Seal Phoca vitulina

The smaller of our two seal species, Common Seals (also known as Harbour Seals) are more commonly found around sheltered shores and estuaries, where they haul out on sandbanks and beaches. When out of the water, they sometimes hold their body in a curved 'banana' position, with their head and tail both in the air at the same time. Like Grey Seals, they feed on fish, but also eat squids, whelks, crabs and mussels. The young are born during the summer.

Behaviour

Can be distinguished from the Grey Seal by its smaller size and shorter head with a blunter, more dog-like profile. Very variable in colour, from blonde to black, but generally grey with dark spots.

Facts

Like all seals, Common Seals live both on land and underwater. When diving after prey, Common Seals usually stay underwater five to ten minutes at a time. Their blood contains far more haemoglobin than ours, allowing them to store more oxygen in the bloodstream. They also limit their oxygen use by decreasing their heart rate to just 15 beats a minute and diverting blood away from the skin and intestines, to keep the brain and heart functioning.
