Association Polydora triglanda bores into the shells of the oyster Crassostrea gigas (Thunberg). [details]Depth range Intertidal to 8 m depth. [details]
Diagnosis A moderate-sized gonochoristic Polydora species boring into mollusc shells and building mud tubes on soft bottoms. Body pigmentation absent. Black bands present on palps in large individuals with more than 60-100 segments. Prostomium incised anteriorly. Eyes, up to 6, usually present. Caruncle reaching end of segment 3; median antenna present. Posterior notopodia with only capillaries. Segment 5 with dorsal superior and ventral capillaries; major spines falcate, with lateral flange, alternating with pennoned companion chaetae. Branchiae from segment 7 usually to end of body. Pygidium disclike or cup-shaped with dorsal gap. Glandular pouches from segment 7, largest in segments 7-9 and drastically smaller in following segments. [details]
Distribution West Pacific Ocean, Taiwan: coasts of East and South China seas, and of Taiwan Strait. [details]
Etymology The specific epithet triglanda, composed by the Latin prefix tri-, meaning 'three', and glanda, from the Latin glans or glandis and meaning 'gland', refers to the characteristic feature of the species, the presence of three pairs of large glandular pouches in segments 7 to 9. [details]
Habitat The species bores into the shells of the oyster Crassostrea gigas (Thunberg) (the holotype is a boring form), and also inhabits mud tubes on soft bottoms and on aggregations of the mussel Mytilopsis sallei (Recluz), occurring intertidally and shallow subtidally in brackish-water environments. [details]
Reproduction Males with spermatids gathered in octads, spermatozoa measured as acrosome 1.9 ± 0.5 µm, nucleus 5.6 ± 0.5 µm, middlepiece 3.8 ± 0.5 µm, flagellum 50 ± 2 µm. Species gonochoristic, gametes present in females and males beginning from segments 20-30. Female paired gonoducts ending externally into two separate gonopores on the dorsal side of fertile segments. Seminal receptacles located in one female after staining with methyl green, located near the inner base of the branchia on fertile segments. [details]
