| Summary: | Rhabdopleura mirabilis (M. Sars in G.O. Sars, 1872) (Fig. 5A) Type locality. Skraaven (= Skrova), Lofoten Islands, Norway, at 100‒300 fm (c. 183‒549 m) on mud. Key features. Inception of ringed erect tubes is direct, with erect annulated zooid tubes produced directly from the creeping tube, not as blind branches. The creeping tube seldom bifurcates and is thickly covered by sediment particles, with erect tubes “always more or less bent in some part … sometimes like an S” (Sars 1872, p. 26). Zigzag sutures were neither mentioned nor illustrated, presumably because of obscuring particles covering the creeping tube, or they may be lacking. The largest colony fragment obtained by Sars was 4 cm long with erect tubes 6‒7 mm long and 200‒250 μm diameter. The living animal (arms, tentacles) was described as being covered by “intensely dark violet spots of colouring matter, which also occur on the buccal shield, and especially on its anterior freely projecting extremity, where they are very close together, forming a ... : Published as part of Gordon, Dennis P., Randolph Quek, Z.
