Experimental study of growth and asexual reproduction in Diaseris distorta (Michelin, 1843), a free-living fungiid coral

摘要: A solitary, free-living fungiid coral, Diaseris distorta, was reared in an aquarium and X-radiographed monthly for one year to study growth asexual reproduction. The corals were treated three ways: 1) hand-split along radially oriented slits, 2) cut into pieces with scissors, 3) without manipulation. number of increased time by radial fragmentation, a result natural autotomy. Fragments, both control hand-split, generated equal numbers daughter segments. Corals that produced more regenerated segments than or because the provided greater periphery from which could regenerate. Growth rate size-dependent. After founder segment ceased horizontal until new, regenerating gained nearly same size as segment.
