Beluga whales live under three feet of ice in the freezing waters of northern Russia’s White Sea which is why they don’t get visitors in these parts that often.
When some underwater photographers arrived, they certainly weren’t shy - as these stunning images show. The whales are not endangered but under threat from pollution and loss of habitat.

At this whale sanctuary, where a natural bay under the ice provides a haven from the strong currents of the wider ocean. Photographer Franco Banfi, who took these shots after his team carved through the ice with a handsaw, said: ‘When a whale comes up to us and swims by, it looks you right in the eyes'.Obviously we don't know what they think, but they are very curious creatures.

But while the beluga, or white whale, is built for these harsh surroundings, the diving team face extremely tough conditions to get close to the gentle creatures.
Before each dive the team have to create holes in the three-foot-deep ice using a hand saw, just to get through to the sea below.Once they're in they have to swim around in heavy layers of clothes to keep alive in the -10C waters.

And it's definitely a case of choosing the short straw for one volunteer who gets to stay above ground in -30C winds, making sure the ice hole doesn't freeze over and trap the group.
Because of the ice-layer and snow cover, there is not sufficient light to shoot with ambient light and batteries lose their charge more quickly in cold weather. Cold itself will not hurt the equipment, but it may slow down some of its functions.
On why I sharing this post here?...it was because Franco added that he was keen to show the beauty of the undersea world to those who can't face the icy deep themselves.
'As photographer, I've always been driven to bring photographs of animals one hardly ever sees to a printed page,' he said.
'I want to see these amazing animals in a way that only a few people have seen and I want to share it with others.'
