The effects of the exudate (crude and its organic extracts) obtained by Arenicola marina (Annelida: Arenicolidae) were evaluated through acute toxicity bioassays on the annelid Dinophilus gyrociliatus.

Abstract
The effects of the exudate (crude and its organic extracts) obtained by Arenicola marina (Annelida: Arenicolidae) were evaluated through acute toxicity bioassays on the annelid Dinophilus gyrociliatus. Preliminary chemical analyses were also performed. The exudate and its n-buthanol extract were toxic (LC50 24h=12%, c.i.=9.7-14.7% and 31.7 mg l-1, c.i.=27.9-36 mg l-1, respectively). The results support the hypothesis that the exudate could be involved in the chemical defence of A. marina.
