Classification provided by the World Register of Marine Species (WoRMS). [141414<\/a>]<\/p><\/div>Taxonomic note: <\/strong>WoRMS defines this species as a synonym of Runcina ferruginea<\/em>, however a recent molecular analysis (still unpublished) between specimens of R.ferruginea<\/em> from the UK, and specimens of R.zavodniki<\/em> from the coast of Croatia resulted in clearly different species (Jakov Prki\u0107, pers.comm.).<\/p>\n

Description
\n<\/strong>Very small in size, the maximum reported length is 3.5mm. The body is elongated and streamlined, coloured black, including the foot and the three gills. One individual was found to be pale orange-brown. Three pinnate gills were present, and each one bore regular pinnules on either face. No shell is present.<\/p>\n

Biology
\n<\/strong>Several specimens were found among mixed algae (especially Ulva rigida<\/em>) but many more were found among the rootlet system of the hydroid Eudendrium<\/em> in the shallow sublittoral (down to 2 m).\u00a0They look and behave like triclad turbellarians.<\/p>\n
