Description A digging bristle worm with an oval, flattened head bearing two long palps covered with numerous
papillae. The long filiform body (up to 170 mm) can be separated into two different regions, each
characterised by short parapodia. The anterior region is coloured pale pink, the posterior region greenish grey with white patches. [details]
Distribution The distribution of Magelona johnstoni was in both periods limited to the near-coastal zone, where the species was characterised by a rather uniform distribution and a high relative occurrence. Whereas M. johnstoni was found in maximum densities of about 200 ind./m2 in the 1976-1984 period, higher densities were found in the 1994-2001 period (up to approximately 9,000 ind./m2) [details]
Habitat Although Magelona johnstoni is only absent in coarse-grained sediments the species displays a clear preference for finer sediments (150 to 300 μm), where the species reaches a relative occurrence of > 40%. A similar spectrum of occurrence is found with regard to the mud content; Magelona johnstoni reaches the highest relative occurrence in sediments with a mud content of 10-20%. [details]
