Editing River Shannon (section)

===Creatures===
The Shannon reputedly hosts a river monster named Cata, the first known mention being in the medieval [[Book of Lismore]]. In this manuscript, we are told that [[Senán mac Geirrcinn|Senán]], patron saint of [[County Clare]], defeated the monster at [[Inis Cathaigh]].<ref>[http://www.clarelibrary.ie/eolas/coclare/folklore/folklore_survey/chapter8.htm A Folklore Survey of County Clare: Supernatural Animals] {{Webarchive|url=https://web.archive.org/web/20110907080705/http://www.clarelibrary.ie/eolas/coclare/folklore/folklore_survey/chapter8.htm |date=7 September 2011 }}.
