Shimmering clearest blue and stretching as far as the eye can see, this is one of Iceland's famed crystal ice caves. The giant solid waves look frozen in time but they are slowly moving along as part of the Vatnajokull Glacier – which stretches across eight per cent of the island. The images were captured in February 2014 by British photographer Rob Lott, 49. Photo: A wide view of Rob Lott in the crystal ice cave in the Vatnajokull Glacier, Iceland.

A family of baby brown bears appear to be dancing to Ring a Ring o' Roses as their mother relaxes behind a tree nearby. At just a few months old, two young males and one female gather in a circle, clutch each others' hands and begin to dance to the popular nursery rhyme.
