Dear Colleagues,

Monniot's 1990 review on the diseases of ascidians only mentions polychaetes as coincidental in the branchial basket of these animals. While collecting Phallusia nigra in the Red Sea, we found an individual in which a polychaete had tunneled through its tunic and was living in the excavated galleries. I have not been able to come up with any literature mentioning this, let alone a way of identifying the animal. Has anyone observed something similar from any other part of the world or host?

Any clues are appreciated,
