The toxic effects of the coloured mucus produced under stress conditions by Halla parthenopeia (Polychaeta: Oenonidae) was assessed by means of a battery of ecotoxicological tests that included bacteria, protozoan, rotifers, polychaetes and crustaceans. Coloured mucus was toxic at concentrations ranging from 70.000 to 300 mg l-1 (in terms of LC50 values) depending on the tested species. Results suggest that the coloured mucus should play a role in the chemical defence of H. parthenopeia.

Abstract
The toxic effects of the coloured mucus produced under stress conditions by Halla parthenopeia (Polychaeta: Oenonidae) was assessed by means of a battery of ecotoxicological tests that included bacteria, protozoan, rotifers, polychaetes and crustaceans. Coloured mucus was toxic at concentrations ranging from 70.000 to 300 mg l-1 (in terms of LC50 values) depending on the tested species. Results suggest that the coloured mucus should play a role in the chemical defence of H. parthenopeia.
