aeolosomatid polychaete DSC 6972
Little syllid of meiofaunal size. Collected in Torre Guaceto marine protected area (Salento peninsula, Italy) South Adriatic sea, in August 2006, hard bottom mainly covered by Halimeda tuna, 5 m depth
I had never seen a worm quite this color before. The body can be bright green, blue-green or brown, and the parapodia lobes light in color. They can be up to 100mm in length, so this was a very "small one". It lives in mucus tubes amongst algal frond or holdfast, or in mussel beds. (Thanks to Marlin Harms for the species ID, as I only knew the genus). Marlin found this beauty. Great day we had, Marlin.
