T. forbesii spawns from November to February. Eggs and larvae are non-pelagic. Like other Opheiiids, it is generaily considered to be a non-selective deposit feeder. T. forbesii is eaten by different kinds of fish (Wolff, 1973; Fauchald & Jumars, 1979; Hayward & Ryland, 1990).

The distribution of T. forbesii comprises the subtidal zone in the western Wadden Sea, the Southern Bight and sorne locations in the Voordelta. Some individuals have been found at the Cleaver Bank, the Dogger Bank and in the north-eastern part of the area.

Like Ophelia borealis, T. forbesii is a short, spindle-shaped worm with a conical head, circular in cross section anteriorly, but without a clear ventral groove in the hind part. The body is made up of 30 segments and rneasures about 30 mm in length and 7 mm in width. Parapodia are inconspicuous, but finger-like gills are present from the second segment onwards. T. forbesii is whitish or flesh pink in colour and may be encrusted with sand. This species gives of a strong garlic-like smell when collected (Hartmann-Schröder, 1971; Hayward & Ryland, 1990).

The species has been mainly found in medium to coarse sand with a very low silt content. T. forbesii is reported as a species inhabiting coarse to fine sand, and (rarely) mud (Hartmann- Schröder, 1971; Wolff, 1973; Hayward & Ryland, 1990).
