摘要	Gigantidas platifrons(Bivalvia, Mytilidae), the dominant species at the Formosa cold seep, relies on methanotrophic symbionts dwelling in its gills for nutrition. The reproductive patterns ofG. platifronsprovide fundamental information for understanding the population recruitment of this species. However, we know very little about important processes in reproduction, such as gametogenesis and symbiotic bacteria transmission. To this end, we described the developmental patterns of the gonads from nine surveys and juvenile length-distribution from one-year larval traps and detected bacteria in gonad fromG. platifronssamples. Our results show thatG. platifronsis a functionally dioecious species. The reproduction ofG. platifronsis discontinuous, with spawning maturity peak around the fourth quarter of the year. The seasonal reproduction ofG. platifronswas further supported by the unimodal shell length distribution of the trapped juvenile mussels. Given the small oocyte size (48.99-70.14 mu m), which was comparable to that of coastal mussels, we proposed thatG. platifronsdeveloped via a free-living, planktotrophic larval stage before settlement. The blooms at the water surface can also supply the development of the planktonic larvae ofG. platifrons. Meanwhile, no bacteria were observed in gonads, suggesting a horizontal symbiont transfer mode in this mussel. Collectively, these results provide fundamental biological information for an improved understanding of the early life history ofG. platifronsin the Formosa cold seep.
