All white orca is only known in the world

UNDATED (WHDH) -- A killer whale researchers dubbed “Iceberg” was spotted in the Pacific Ocean. It is the only known all-white orca in the world.

The bull male was spotted in a pod of a dozen relatives cruising the northwest Pacific near Kamchatka on the Russian coast.

Erich Hoyt of the Far East Russia Orca Project said the 6-foot dorsal fin of the white whale suggests it is a mature giant of the species, but also very rare.

Other whale species appear in white, almost all belugas, and some humpback whales.

Photos suggest Iceberg could be the same white orca, now grown older, that was seen in 2008 and as far back as 2000, all in the remote northern Pacific.

The Scotland-based researchers will return to the waters to look for Iceberg and to track his movements.
