Development of the deep‐sea viviparous quill worm Leptoecia vivipara (Hyalinoeciinae, Onuphidae, Annelida)
Abstract Development of Leptoecia vivipara , a brooding deep‐sea onuphid polychaete with a circum‐Antarctic distribution, was studied using light microscopy, scanning and transmission electron microscopy, and histology. All specimens examined were brooding viviparous females or juveniles; no male ga...
