Siliceous polycystines and phaeodarians are open-ocean planktonic protists found throughout the water column and characterized by complex siliceous skeletons that are formed, at least partly, through the uptake of silicic acid. These protists contribute

A tripartite structure having the same morphological features (two lateral elements and a central element connected by thin threads) as synaptonemal complex, is present during a part of the bipartition division. The first appearance consists of an axial
