The decline of morphologically based taxonomy is mainly linked to increasing species redundancy, which probably contributed to a worldwide disinterest in taxonomy, and to a reduction of funding for systematic biology and for expertise training. The present trend in the study of biodiversity is integrated taxonomy, which merges morphological and molecular approaches. At the same time, in many cases new molecular techniques have eclipsed the morphological approach. The application of Standardised Integrative Taxonomy, i.e. a rigorous, common method of description based on the integration between ecological and morphological characteristics, may increase the precision, accessibility, exploitability and longevity of the collected data, and favour the renaissance of taxonomy by new investments in biodiversity exploration.

The aim of this work is to describe the skeletal morphology of the early stages of the colonies of Stylaster sp., settled on artificial panels placed along a coral reef in the Bunaken Marine Park (North Sulawesi, Indonesia). The youngest observed stage deriving from the planula settlement is represented by a well developed primary cyclosystem symmetrically budding two secondary cyclosystems in a very early phase of growth. Successively each cyclosystem starts its vertical growth producing new cyclosystems sympodially arranged. At the same time the basal disc of the first cyclosystem enlarges producing a flattened crust from which new colonies arise. Vertical and encrusting forms are considered different modalities to face the problem of space competition in marine benthic organisms. The colonies of Stylaster sp. grow using both strategies resulting in the asexual reproduction of several colonies from a single settled planula. The new cyclosystems originate as small volcano-like elevations having the centre filled with calcium carbonate. Gradually this calcareous matrix dissolves starting from its perimetric zone and leads to the formation of the gastrostyle and the ring palisade. It is plausible that the cells composing the stolon nets deeply pervading the calcareous structure are responsible for this skeletal plasticity.
