Request For All Crayfish Keepers

[black_sun]

I have a request for anyone who keeps crayfish, as pets or feeders:

If you have a camera with flash, could you take pictures of your crayfish (any species, morph or hybrid) so that they produce eye shine in the photograph?



A friend of mine pointed out (of photographs he's seen or taken) that white crayfish produce a white eye shine when photographed with flash. Where as any other species or color morph seems to display an orange, yellow or red eye shine.

I ran through all the photos I've taken, and this seems to be true. But I was curious to see if exceptions could be produced in other species, color morphs and white morphs. I'm kind of curious as to why the white morphs seem to be the only ones producing white eye shine, but I'd like to see if I can find any exceptions to this before continuing research on it.

Thanks to anyone who chooses to help out!

Oh, and I hope everyone has a wonderful New Year!

Haha, thanks Yabba.

This is all stemming from the ever popular "Are White Morph Crayfish Albino or Just Morphs?" debate. I had never really delved too deep into either side of the argument in the past, but when my friend pointed out the eye shine anomaly in one of my pictures he brought it up. I became curious if the white eye shine was perhaps the compound eye's version of showing albinism, where as the non-compound eye displays the pink/red coloration in lieu of actual pigmentation. So, while doing light research on albinism, I'm also trying to see if I could find an exception in the eye shine anomaly. It's certainly an oddball thing I'm up to, but it's become really fun!

See, these produce a very white eye shine in all the photos I have of them. I even have a picture with this male and his orange morph girl, and she shows a red eye shine while he still has the white. It's weird lol
