I don't know what this quiz is supposed to be about. Any fish? If so, there are plenty that it doesn't recognise. If not, then what are the criteria for a valid answer?
What this quiz is about? Really? I think the title and directions speak for themselves. If you took the quiz you would see it's about fish. This comment is a waste of time it seems to me.
This was a fun quiz in my opinion. I managed to think of 48 types of fish. There were many fish that I typed in, but which were not accepted. I typed "gobies," not thinking to try the singular, so I got nothing for that. I was surprised that goby is in the list, but blenny is not--those two go hand in hand--or fin in fin. Topminnow, dace, char, grayling, wolf eel, electric eel, torpedo ray, pumpkinseed, jack, clownfish, skipjack, albacore, kelp greenling, surgeonfish, muskellunge, pikeminnow, sauger, and many more were not accepted. I'd like to see this quiz expand by a hundred or two fishes!
I tried going for fish that the general public would know. I don't think the general public would know what a "blenny" or "greenling" are. Also just putting "eel" instead of naming the different species, would make it easier for quiz takers.
A total waste of time, it seems to me.
