Re: sometimes humans have to manually label the pictures
If you were given 30 images of the fish in question and asked to compare I'm sure you would be 100% accurate.
It may take a while depending on the $animal and you may be bored out of your skull by then end of the process. But that is what this is, it's like the silhouette puzzles or a Where's Wally/Waldo). Your given the relevant info, you just need to study it.
