One well documented encounter between primnoan corals and a Canadian trawler doing a trawl survey in the canyon between Georges Bank and Browns Bank - even though it was a coral conservation area. See photos of the result at http://tinyurl.com/coral-dragged
I presume whoever wrote this headline thought it was cute, but there is no reason to be insulting when making a point. As the expression goes, it's possible to disagree without being disagreeable.
Greg's question was obviously not "shallow" since your answer is that none were seen. Your additional evidence is interesting and worthy of consideration,
I think it's in really poor taste to even infer that Mr. DiDemenico's question was shallow. Why wouldn't one in his position want proof before he's lead off the deep end. Kind of a built in adversarial assumption going on here, But then I've mentioned that before.
