Check it out, this mutation is known as a split. As I've posted before the most common mutations are Blue being 1 out of 2 million, Callico 1 out of 20 or 30 million. These are 1 out of 50 million. Really makes you wonder how much mathmatics is involved in nature,

 

Could've just part boiled him.

 

Could be a chimera, the two halves being genetically different:

There's some good ones a bit down this page:

reminds me of ants. when red ants invade black ants and steal there eggs or vise versa.
They'er genetics cant decide what they should be so they turn out part blk and part red

 

What are the chances that the coloring would be on a perfect straight line boundary? Are there any other instances of this in nature?

 

I saw this on Star Trek. It did not end well.

Thats why I said its amazing how much mathmatics is in nature. Spider webs, a drop of water, and crystals for all kinds of crazy geometric shapes. Nature is full of geometry if you look for it.

As for other instances yes. Look at dogs, we've been inbreeding them so long you can do it with them. The only other domesticated animals we've activily been mutating and breeding are parrots and snakes. And they've done amazing things with both by isolating colors for the birds, and making new patterns and even scaleless snakes. I know a baby scaleless boa sells for $10,000. With birds it goes by what colors are hardest. Typically you'll have a normal green for $100, a Lutino will come next for $250, then a blue will come for $400, Then a proper yellow will come out for $5000, Then you still have violets, greys, lacewings, etc.. the lists goes on and on and they pay big dollars for the first mutations so breeders can breed them. So a bird comes out this year for $5000, in 2 years its selling for $500.

 

Maybe Loosie is doing something in the ocean other than diving?

 

Don't forget Koi - that is very serious stuff.
