The photo on the cover page illustrates a marine demosponge Tethya lyncurium (from the Adriatic Sea) with asexual propagation bodies (buds). These buds are attached via thin stalks (made from biogenic silica) to the parent. If environmental conditions are suitable, they drop off, become free and drift away. On a suitable substrate they settle and form a new specimen. For further details, see article by Perovic-Ottstadt et al. pp. 293-305 in the current issue.
