Resumen:
Aulacomya atra populations of the San Jose gulf, Northern Patagonia, Southwestern Atlantic Ocean, areinfested by two polydorin species, Polydora rickettsi and Dipolydora cf. giardi. The infestation by theseboring polychaetes causes the formation of pearls which is evidenced by the presence of capsules containingpolydorin tissue debris and the elemental composition of organic material inside the pearls.Moreover, a positive relationship between the abundance of perforations of polydorin polychaetes andabundance of pearls was found by applying generalized lineal model analysis. These results constitutethe first evidence of pearls formation due to infestation by polychaete.
