Unreviewed: has not been verified by a taxonomic editorBiology Grey seals breed during winter. They are less shy and more curious than the harbour seal. Young, grey seals must stay out of water until they have gained weight and moulted and for this reason they remain in a raised location for the first few weeks of their life.


Grey seals feed mainly on mackerel, young cod and other round fish, but also on cephalopods and crustaceans, in contrast to harbour seals which eat more flatfish. [details]
