Hello;
I am interested in knowing what color morphs of the common american bullfrog are known, and what are being reproduced in captivity? I have recently found a group of bright yellow (not amelanistic though) bullfrogs in a friends koi pond. I believe they are bulls rather than leopards, but could be leopards, as they are a bit young so I have a hard time telling and the morph color is confusing too. They are very stunning and bright. My friend says I can have them if I help drain and clean the pond. They do fine outside year round being wild animals that have just moved intot he garden pond, so I would like to set up a netted small pond for them in my garden and reproduce this morph. Anyone out there working on native bull or leopard frogs? I will try to get pics when I catch the frongs. Thanks in advance for any help.

bulls and leapords look nothing alike. bulls are larger, have wider mouths and a more blunt snout, are not spotted, and the difference really shows when they are young. leapords are smaller, only growing at max to half the size of bulls, have narrow mouths and pointed snouts, and are "freckled" with black spots. the probility is that you are looking at green frogs if you believe that they smomewhat resemble leapords. green frogs look like smaller bulls, but with a more narrow mouth and pointer snout, they have spots as juves and as adults are usually a light green to almost yellow color with the right temps and no stress. attached are pics of an adult and junenile green frog from my collection.

They are bullfrogs then. Thanks for the infoon the bullfrog morphs.
