An investigation into the toxicity of tissue extracts from two distinct marine Polychaeta
The present study investigated the potential toxicity of venomous secretions of two polychaetes, Hediste diversicolor and Glycera alba (Annelida: Phyllodocida). Toxic activity of putative toxins, measured on mussel gills through the Comet assay, revealed higher effects caused by extracts from H. div...

| description | The present study investigated the potential toxicity of venomous secretions of two polychaetes, Hediste diversicolor and Glycera alba (Annelida: Phyllodocida). Toxic activity of putative toxins, measured on mussel gills through the Comet assay, revealed higher effects caused by extracts from H. diversicolor skin and G. alba specialised, jawed proboscis, when compared to control. The results suggest that H. diversicolor secretes toxins via skin for protection against predators, contrarily to G. alba, who secretes toxins for predation. |
