Russian scientists said Monday they have been the first to spot what they believe is the world's only all-white full-grown male orca whale, in the chilly waters off Russia's Far East coast.

A team of scientists from the Far East Russia Orca Project (FEROP) spotted the whale, which they suspect is an albino, swimming with his pod in the North Pacific, near the Commander Islands.

They say the whale, who they believe is about 16 years old, swims in a pod that includes 12 other whales.

The team has named the unique mammal Iceberg, saying the moniker came to them after watching his two-metre dorsal fin break the ocean's surface.

On Monday, they released a brief video of Iceberg swimming in the ocean.
