Overview

Brief Summary

Biology

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).

Physical Description

Diagnostic Description

Morphology

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).

Ecology

Habitat

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).
