Is this an AEFW?

[BantyRooster97]

So I bought 4 SPS frags from a local seller today and when I dipped them the bowl was full of all kinds of stuff. Some I could tell were pods and other non harmful things but then I saw 6 of these (see pic).
I got 1 more off of them when I started to rinse. Is this AEFW? I emailed the seller and he said he has never had a problem with them before.

If it was on an acro, and there are little white spots on the underside, the chances are that it is.
