During the growth of hydrothermal vestimentiferan Oasisia alvinae the trunk part of body was found to be elongated (from 51 to 83.4% of the overall body length), while the relative dimensions of all other body regions decreased. This was related to the enhanced trophosome and gonad development in the trunk part. We suppose that predominant trunk growth is a common feature of all vestimentiferans.
