Theres not really morphs, but subspecies. There is coastals, jungles, irian jayas, bredls, and diamonds. Coastal are tend to grow the largest while irian jayas stay small in the 5 foot range. But a good sized coastal can get 10' but 7-8 is more common. You want a high yellow and black carpet. So you want a jungle carpet. Thats what i have. A trophy jungle can run you anywhere from 350-800 dollars. Go to faunaclassifieds and find Steve from Sek Exotics. He has some of the best jungles in my opinion. I just got my jungle from him about a month ago and hes beautiful. Young and already got the high yellow. His username on faunaclassifieds is SEKCOBRA. Give him a shout and see what he has available. I just saw some of his third clutch last weekend at the white plains expo and there going to be some great snakes.
