Alien-like surreal world hidden underwater at White Sea

Daring ice divers plunge into freezing cold water and explore the surreal depths at the White Sea in Northern Russia, the only European sea that freezes over during the winter. The divers compared the experience to "visiting Mars" because of the alien-like colors and "strange" underwater landscape. Photographer Viktor Lyagushkin captured the underwater world beneath a 3-foot layer of ice, including sea angels, stalked jellyfish and sea walnuts. [File Photo: VCG]
