Genetic identity of two physonect siphonophores from Southern Ocean waters – the enigmatic taxon Mica micula and Pyrostephos vanhoeffeni
Based on some coincident morphological characters and distribution, it was believed for a long time that Mica micula was the post-larval stage of a species of Bargmannia , a genus having a very wide geographic distribution. Recent studies, however, have shown that it is much more likely to be the po...
