CARNIVOROUS fits the length and what might be the definition, but doesn't appear to fit anything else.

It's something like ----COPHAGE or (more likely) --COPHAGOUS, I think - but the Koranic verses bit has me stumped, and the whole is (I reckon) a word I don't know.

Got it, it's SARCOPHAGUS. The COP/HAG part is at Wol suggested, and it's surrounded by SURAS, i.e. Koranic verses, except it's backwards, which there's no indication of. The definition part is cleverly obscure, I had to search for this to confirm it. , Koranic verses might be indicating SURAS, but SURAPHAGOUS SARCOPHAGUS

Ignore the fragments after the part that makes sense.

[Raak, Wol] Thunderous applause Good work.
A spot on the unfair side, I think; the experiment was in judging difficulty. If you hadn't got it, I'd have reposted as Flesh-eating Greek crone.... I do wish I could find a way to indicate the reversal of SURAS without losing the neatness and sense of the clue...
