I don't think that is the case. I have never seen a specimen or
illustration with flared labrum, and most turbinellids do not develop
such a terminal varix (some Vasinae excepted).

I think this is a variable trait. Some lage specimens have a
dead-straight canal. I have a small one (~130cm) with twisted canal.

I can't be certain, but I believe really big ones can be found
crawling awash at low tide on mudflats. Despite what I've read on a
website, I doubt these shails eat carrion, other molluscs or
vegetation. Other turbinellids eat worms, and I'd bet Syrinx is no
exception.
