To point out parts unknown (terra incognita) is an absolutely essential scientific act of pioneering, as the historian Yuval Noah Harari explains in his “Sapiens: A Brief History of Humankind”:
"With the discovery of America, the Europeans learned to put more emphasis on new observations than on old transmissions. Soon not only the cartographers but also European scientists of all other disciplines learned to draw maps with blank spots. They admitted that their theories were anything but complete and that there were a lot of things they yet didn't know anything about. The maps’ blank spots had magical attraction for the Europeans, and they set out to fill in one by one."
Thus, in case you should feel irritated about the many parts unkown in the FishEthoBase's findings, please do not point at us. We admittedly did it on purpose – because these unknown parts really are there.
