Born with rare brownish-red fur and wonky blue eyes, he was rescued from a beach on an island off Russia, in the Caspian Sea, after it was abandoned by its mother.
The pup's colour is the result of an accumulation of iron in its fur. And he's almost completely blind.
Photographer Anatoly Strakhov found the baby on Tyuleniy Island, away from the other seals on the beach.
"He was hiding and waiting for his mother to come and feed him," Mr Strakhov said. Mr Strakhov caught the seal and took it to a dolphinarium where it is being cared for.
