i'm no expert on the subject,but my understanding is a leucistic is all white or yellow with dark eyes. and a hypo is just a lighter skin and shell color(pinkskins). email john richards on the matter. in my opinion a leucistic is an albino without pink eyes. i believe snappers throw off various colors to match thier enviroments,( stemming from thier parents and the color sand they were hatched in.} any more opinions?
