One of the things I love most about reef tanks is discovering and identifying new creatures. Yes, some of it can be problematic (as per yesterday's post) but some of it can be hands down cool too (well certainly to me anyway).
Last weekend I noticed an unusual disc thing attached to the zoanthid rock (yes again the zoa rock, it's just full of surprises, lol!). I was immediately curious to find out what it was. It's a sessile flat disc measuring just 2mm across. To the naked eye it doesn't look like much but on closer inspection (with a macro lens) it has a beautiful radial pattern with a distinct middle section. My initial thought was a type of foraminiferen which belongs to a group of single-celled organisms (protists) with shells. I decided to request the help of an expert at foraminifera.eu to help with identification. He confirmed that it is indeed a sessile benthic foram called Marginopora vertebralis. Pretty cool huh!
