Polydorid species (Annelida: Spionidae) associated with commercially important oyster shells and their shell infestation along the coast of Normandy, in the English Channel, France. Aquaculture International, 31(1), pp. 195-230. Comments: P. onagawaensis is a shell-boring spionid polychaete, especially known from cultured oysters and scallops. |

Reproductive frequency (?) | Iteroparous |
Reproductive type (?) | Sexual References: Teramoto, W., Sato-Okoshi, W., Abe, H., Nishitani, G., Endo, Y. 2013. Morphology, 18S rRNA gene sequence and life history of a new Polydora species (Polychaeta: Spionidae) from northeastern Japan. Aquatic Biology, 18(1), pp. 31-45. Comments: Females deposited up to 49 egg capsules in a single string, attached to the burrow wall, each of them usually containing 60 to 70 eggs, with major and minor axes ca. 110 and 100 µm. |
Developmental trait (?) | Brooding References: Teramoto, W., Sato-Okoshi, W., Abe, H., Nishitani, G., Endo, Y. 2013. Morphology, 18S rRNA gene sequence and life history of a new Polydora species (Polychaeta: Spionidae) from northeastern Japan. Aquatic Biology, 18(1), pp. 31-45. Comments: Brooding worms were present from around October to June, with a peak in December each year and 2 minor increases in March and May. Spawning was rarely observed during summer. All eggs developed simultaneously; no unfertilized or nurse eggs were found. From the 1- to the 3-chaetiger stage, the larvae contained yolk, which appeared partially depleted, in the center of the body. |

Comments: P. onagawaensis is one of several species of shell-boring polychaetes which create mud-blisters inside the shell, reducing growth rates, meat-quality, and affecting the aesthetic appearance of the shell and the seafood-eating experience. Polydora onagawaensis sp. nov. forms U-shaped burrows that never branch. They were able to feed and swim immediately after hatching. |
