Northern Green Frog

Hi acallejas. Thanks for the dolphin ID suggestion. I am wondering what was your reasoning? The wiki article that you reference says the species you suggested is grey and the specimen is black, and also the size of the specimen is I think smaller than noted in the wiki reference (but of course it could be juvenile). I know it is hard with this photo b/c so much is below the water, but just wondering how you distinguished this from the other possibilities. Finally, if you do have expertise in dolphins, I would love it if you could also check this spotting of mine taken in New Zealand Doubtful Sound: https://www.projectnoah.org/spottings......
