It may be that Kisame's transformation was more like Juugo's, which is related to Sage Mode.

maybe he did, his look is more human than anyone else's sage mode (maybe he learned it from buddha XD) Well anything is possible i guess. Remember that an incomplete sage mode transforms you into the Sage Animal (e.g. Jiraiya became very toad-like). Perhaps Kisame attempted Sage Mode, failed and is stuck in a sort-of inbetween ever since?
