抱歉，忘了放图了

神话里很多龙都是冠以龙称的大蛇或者大鲵，不知道你看的哪本书，不好作答

我把文字提取出来了：“江河湖海中也各自有怪:密西西比河中有比亚萨,澳大利亚有所有人都害怕的彩虹蛇神。非洲的西海岸则据说是被一条名为埃多维多的彩虹蛇神用利爪挖出来的。”

我翻遍了《幻兽•龙事典》也没能找到有关这个“埃多维多的信息

比亚萨的资料倒是找到了，以下内容复制自维基百科

ThePiasa(/ˈpaɪ.əsɔː/PY-ə-saw) orPiasa Birdis a Native American mythical creature depicted in one of twomuralspainted byNative Americanson bluffs (cliffsides) above theMississippi River. Its original location was at the end of a chain of limestone bluffs in Madison County, Illinois at present-dayAlton, Illinois. The original Piasa illustration no longer exists; a newer 20th-century version, based partly on 19th-century sketches and lithographs, has been placed on a bluff in Alton, Illinois, several hundred yards upstream from its origin.

果然自己动手丰衣足食
埃多维多的资料也在鳞目界域的龙百科里找到了
