Goran Ehlme takes pictures of walruses as they swim underwater.
The water he dives in is very cold and he has to wear a really thick diving suit to keep warm.
The first time he went underwater with walruses he was very scared, as the animals can be rather grumpy!
But now he understands their behaviour and takes pictures of them as they feed.
Goran thinks walruses are very nice creatures with a lot of character
