What's the source on this particular spelling? --Sabrblade (talk) 00:26, 9 March 2015 (EDT)
There isn't one - it was my best guess at the spelling, since it seemed to be a portmanteau of ray (from manta ray) and ravenous. I have tweeted to Shannon McKain to ask what the correct spelling is though! --abates (talk) 01:17, 9 March 2015 (EDT)
