Here is a photo I took of our very own blue bullfrog here in Oregon. I had no idea they were that rare, and only seen once in a blue moon. (sorry). I found it in one of the ponds near our house in 09/09/ this year.
I only wish all of the green ones were as rare. They have become an infestation, and most are still too small if anyone cared to eat them.
Looks pretty pleased with himself, doesn't he.
Regards & happy holidays,

CLEVELAND — Wildlife experts call it a “one in a million” find, and that’s exactly what happened to one Ohio man who encountered a blue bullfrog recently in western Ohio.
Matt Minnich was especially lucky to encounter this rarity. The frog becomes blue when it has axanthism, a mutation that interferes with an animal’s ability to produce yellow pigment.
“It's an extremely rare situation. Basically, it's just a color or lack of color combinations. So basically, it's a genetic thing that would be caused by a recessive gene,” said Brian Banbury, executive administrator for Information and Education for the Ohio Division of Wildlife.
According to a Rhode Island Division of Fish and Wildlife report, a national study by Cornell University researchers found 69 blue frogs during a survey of 2 million, which comes to a frequency of 0.003%. The study found it may be more common in some regions than others, including several New England states.
