Orlando, that's a very pretty snake. However, I'm going to play the Devil's advocate right now and say...how can you tell that they're kastanie? Just curious, as I'm red-green colorblind and the slight differences in color you're using to distinguish between a regular anery and one showing kastanie...I simply might not physically be able to see. Thanks!
Mitch
Mitch,
You bring a good point....
how can you tell that they're kastanie?
I think it will be best for me to have a picture side by side from a few Anery siblings to note the difference or even better a bucket shot with a white background. As you know, when Kastanie cornsnakes are born they have a fair resemblance to an Anery Type A cornsnake. Not until a few sheds (For me I usually wait at least 3 -4 sheds) that we are able to tell the difference.
When Anery Type A & Anery Kastanie are mixed.....well is like opening a can of worms...... Again, it will be best to have a group shot to tell the difference but I look for a few markers. Also the fact that the snake gets even lighter with every shed (compare to the others) is good hint. Another indicator to look for is around the neck, lateral and slight ventral carotenoid (yellow pigment) coloration that tends to become more prominent. However, some Anery Type A develop similar phenotypic variation but the yellow tends to be subtle and lighter rather than the deep caramel-like coloration.
****If Tom is reading this....(If possible) I would be neat for him to post a picture of his Caramel Kastanie for comparison********
Yellow Arrow - Lighter coloration and continuos throughout the body.
Orange Arrow - Deeper grey fades away.
Red Arrow - Carotenoid coloration (Caramel-like) becomes prominent with every shed particularly in the proximal 1/3.
If we think that Anerythristic Kastanies are tough to see the effects of the gene when compare to an Anery Type A; then, imagine when the snow gene comes into place.
I planned on using this Adult male Anery (He could well be an Anery Kastanie as he came from a Kastanie breeding done by Don) to test him with a kastanie female to see if he is in fact an Anery Kastanie.
Take care!
Orlando
