Well, whatever he is, he supposedly is being picked up tonight. He is one of the three fosters I took in, and the rescuers are going to come pick their 3 snakes up. Ahh down to 4 snakes(2 boas and 2 juvie corns) 1 gecko and a mouse breeding colony.
I did some searching and to me Ai looks like a cross between a Murrays and an Irian Jaya. Too much black on his back and not enough yellow to be a JCP, and too mottled markings to be a Costal (Plus he isnt that big- but supposedly he is a juvie. Hes grown a bunch in the past nearly 2 months, so I dont think he is full sized yet.) Most if the IJs Ive seen are more yellow/brown saddles- not black with creamy white in between them. But the pattern on the face is spot on for one, which is why several I talked to thought it may well be.
