This article states that “the resulting blurred view is good enough for spotting large objects such as mangrove roots.” It seems to me that the article is missing the crucial biological question presented by these eyes. My understanding is that the nervous system of a jellyfish contains no true nerves and no centralization. How can the simple neural net of a cnidarian interpret any image, blurry or not?
