Notes 
From other sources
Unreviewed: has not been verified by a taxonomic editorBiology No information on this species' reproduction is availabie. S. mathildae lives 15 to 20 cm beneath the surface of the sediment. The sigalionids are generally considered active, free- living carnivores, feeding on a variety of small invertebrates. Specific information about S. mathildae is lacking (Fauchald & Jurnars, 1979; Hayward & Ryland, 1990). [details]

Unreviewed: has not been verified by a taxonomic editorDescription A bristle worm with a sturdy, elongate body with numerous segments and a maximum length of 150
mm. The worm is dorsally covered with soft scales (elytra) whose outer edges feature a characteristic fringe consisting of pinnate papillae. The head bears three minute antennae (two lateral ones and one in the middle) and two pairs of small eyes. [details]

Unreviewed: has not been verified by a taxonomic editorDistribution S. mathildae is most abundant at the Dogger Bank and in a broad zone south of the Frisian Front. The species is absent from the central Oyster Ground and from the Southern Bight, except for occasional finds near the coast. S. mathildae is neither present in the Wadden Sea, whereas in the Delta area it occurs only in low numbers in the marine part of the Oosterschelde. [details]

Unreviewed: has not been verified by a taxonomic editorDistribution The distribution of Sigalion mathildae was in both periods more or less limited to the western coastal zone, where densities up to 20 (1976-1986 period) and 200 ind./m2 (1994-2001 period) were observed. [details]

Unreviewed: has not been verified by a taxonomic editorHabitat The species is most frequently found in fine to very fine sand with little or no mud. [details]

Unreviewed: has not been verified by a taxonomic editorHabitat Sigalion mathildae prefers a very specifically defined sediment type characterised by fine-grained sediments (median grain size 150 to 250 μm) and the presence of a low mud content (maximum 20%). [details]

Unreviewed: has not been verified by a taxonomic editorMorphology S. mathildae has a long, robust body with a maximum length of 100 mm and about 200 segments. The body is dorsally covered by soft scales (elytra) of which the outer edges have a characteristic fringe of pinnate papillae. The head bears a pair of minute lateral antennae and four small eyes. The body segments have prominent bilobed parapodia with complex chaetae. The first segment is directed alongside the head and has additional finger-like cirri. Two big palps project forwards from underneath the first segment. The worm is greyish white in colour, with an iridescent underside and a prominent red mid-ventral blood vessel (Hartmann-Schröder, 1971; Hayward & Ryland, 1990). [details]
