White orcas sighted off the coast of Japan

-Whale-watchers off coast of Japan’s northern island Hokkaido spotted two white orcas swimming together
-One was an older animal first spotted two years ago, but second was younger and had not been seen before
-The two orcas are not thought to be albinos but to have leucism, meaning they still have some skin pigment
-That means their markings are still faintly visible and their eyes are still dark instead of being bright red

The pair are part of a pod that contains mostly normal-looking orcas, but these two are thought to carry a gene which partially removes pigment from their skin – making them appear white

Whale-watchers off the coast of Japan could scarcely believe their eyes after catching sight of two rare white orcas swimming together as part of the same pod.

The orcas were spotted during a whale-watching tour on July 24 in the Kunashirskiy Strait, a 20-mile stretch of water between the northern islands of Hokkaido and Kunashir.

Mai, an employee of the Gojiraiwa-Kanko tour company, said one of the pair was older with slightly darker skin while the other was younger and had clearly-visible scratch marks down its back.

Japanese whale-watchers were stunned to spot two rare white orcas swimming off the coast of Hokkaido, one of the country’s northern-most islands, over the weekend

She said the older whale was first spotted around two years ago but it is the first time she has seen the younger animal and the first time she has seen both of them together.

‘It was the best day ever. This is the first time two white orcas have been seen off the coast of Japan, ‘she said.

The pair are not ‘true’ albinos, which is caused by a genetic trait that means the affected animal produces no melanin at all – the compound that gives skin, hair, feathers and eyes their color.

True albinos will be completely white and have red eyes – a color given by the red blood in vessels which are usually hidden behind the iris showing through.

Instead, these two whales are thought to have leucism – an umbrella term that covers a range of conditions where animals produce some melanin, but either have noticeably whiter skin or skin that is white in patches.

That explains why the white patches that traditionally surround an orca’s chin and eyes are still visible on the two animals spotted near Japan, and why the eyes themselves are still dark.

It may also help explain the scarring down the side of the younger animal – which is particularly visible as the scar tissue seems to have healed in a darker shade compared to the surrounding white skin.

White orcas and whales were once so rare that they were thought to be a myth, but are becoming increasingly common, with scientists aware of at least five individuals alive today.

It is not clear exactly why they are becoming more common, but scientists theorise that it may be down to dwindling numbers of the whales and is a sign the species is in trouble.

As the population of a species declines, so does its genetic variation because the animals left have fewer potential mates to choose from.

White whales and orcas are becoming more common – which scientists think may be due to falling numbers of the animals which decreases their genetic variation, meaning rare traits crop up more often

Depending on the genes carried by those remaining individuals, it could accentuate some traits that were previously thought of as genetically rare.

That includes rare genetic disorders that hamper an animal’s ability to survive in the wild, threatening to accelerate the species’ decline.

While it is not known exactly what effect the leucism has on the lives of the orcas that inherit it, it does make them more visible – potentially hampering their ability to hunt, and attracting unwanted attention from rivals.

However, the trait is not always harmful. For example, Kermode bears are traditionally black but are increasingly being born white thanks to a recessive gene.

Scientists have found the trait leads to them catching more fish because salmon find it harder to spot them.


And I mean…Let’s just hope they swim away from Japan as soon as possible – Japanese hunters have a thing for whaling, whale murder and whale trading.

And it would be better if the media didn’t make so much fuss about the news.
Because there are many zoos that would also be interested in these beautiful animals, catch them in a tank and earn money with the captives

My best regards to all, Venus
