An "extremely rare" white humpback whale recently made researchers' jaws drop when it surfaced above Cook Strait waters off New Zealand.
The white whale was photographed on Monday swimming side-by-side with a buddy, a more common black humpback whale, the New Zealand Department of Conservation (DOC) said in a statement today.
"Only four white humpback whales have been reported in the world," said Nadine Bott, the leader of the boat's survey team counting whales passing through Cook Strait.

Bott said there is a promising indication humpback whale numbers are increasing in our waters.
The DOC added it believes the spotted white whale is Migaloo, which literally means "white fella" in an aboriginal Australian language.
"Migaloo is the most famous" of white humpback whiles from Australia, Bott explained adding that he "is thought to have fathered two white calves which have been making appearances along Australia's eastern coast. One has been named MJ, short for Migaloo junior."
Researchers said they will do a DNA test from a skin sample they got from the whale to confirm whether the whale is in fact Migaloo.
The analysis will also reveal whether the whale is albino or whether its whiteness is due to color variation.
"This is so unique," said marine mammal scientist Carolos Olavarria, who was with Bott during the sighting. "I have never seen anything like this in New Zealand."
