E. sanguinea breeds in early summer and has planktonic larvae. In the estuarine Delta area juvenile benthic stages are mainly observed in June-July. E. sanguinea is a predatory carnivore and is itself eaten by fish. The species has been observed to live as a commensal of the tubicolous polychaete Lanice conchilega (Hartmann-Schröder, 1971; Wolff, 1973).

Description
provided by World Register of Marine Species
Bristle worm with a rather corpulent, ventrally flattened body up to 60 mm long. The uniform segments feature distinct parapodia on which the dorsal lamellas are clearly visible. The head has two large black eyes and five antennae, one of which in the middle of the head. Four pairs of rather long, thin tentacles. The colour varies from greyish white with brown spots to reddish brown with white transverse bands. Eumida sanguinea often lives in association with the sand mason Lanice conchilega.

Distribution

Eumida sanguinea mainly occurs in the near-coastal zone. In the 1976-1986 the species had a low frequency of occurrence but was found across the entire near-coastal zone. The density was limited to a maximum of only 800 ind./m2. In the 1994-2001 period the frequency of occurrence increased, but the species appeared to be absent in the eastern coastal zone. The highest frequency of occurrence and density levels (up to 3,500 ind./m2) were observed in the western coastal zone and in the southern part of the Zeeland Banks.

Habitat

E. sanguinea has been reported from muddy sand, among algae and also under stones, in kelp holdfasts and among old shells (Hartmann-Schröder, 1971; Wolff, 1973; Hayward & Ryland, 1990).

Habitat
provided by World Register of Marine Species
Eumida sanguinea occurs in a wide spectrum of sediment types: the species only avoids sediments with a median grain size > 500 µm or with a mud content > 40%. An optimum is reached in sediments with a median grain size of 150-250 µm and a mud content of 10-40%. The high relative occurrence in sediments with a mud content of 80-90% is considered relatively unreliable in view of the low number of observations for this mud content.

Morphology
provided by World Register of Marine Species
A species with a stout, dorsally convex body, up to 30 mm in length and made up of 60-140 segments. The uniform segments have distinct parapodia bearing a dorsal lamella. The head has two fairly large black eyes and five antennae. The colour is variable, ranging from greyish white with brown spots through yellowish green to reddish brown with white transverse bands (Hartmann-Schröder, 1971; Hayward & Ryland, 1990).
