Biologist Vladimir Burkanov says that so far this fur seal on Tyuleny Island - nicknamed The Ugly Duckling - has not become a total outcast, yet there are signs of it being slightly shunned.
'This pup looks well fed and was very active, so its mother clearly gave it plenty of milk,' he said.
'Other seals don't pay too much attention to it in a somewhat worrying manner, so something is not quite right with it.
