HabitatLineus longissimus is found on the lower shore coiled in writhing knots beneath boulders and on muddy sand. This species can often be found in rockpools entangled amongst Laminaria holdfasts or in rock fissures. In deeper sub-littoral areas, it occurs on muddy, sandy, stony or shelly substrata.
- Ventral surface may be same colour or paler than dorsal.
- Body may be streaked with pale longitudinal lines especially on anterior dorsal surface.
- Rectangular head with pale colour tip.
- 10-20 deep set reddish brown or black eyes in a row either side of snout, which may be obscured by dark body colour.
- Body unsegmented and ciliated, giving purplish irridescence.
Additional informationLineus longissimus is the most commonly recorded nemertean in Britain. When handled, the animal produces large amounts of thick mucus with a faint pungent smell.
