| Abstract: | Gametes were obtained from adult starfishes kept in closed cycle aquaria with artificial sea water by stimulation with 1-methyl-adenine ( Asterina pectinifera, Aphelasterias japonica ) or during spontaneous spawning ( Lysastrosoma anthosticta ). The eggs were fertilized and their development until the midbipinnaria stage ( Aph. japonica, L. anthosticta ) and settlement and metamorphosis ( A. pectinifera ) was described using scanning electron microscopy. Special attention was payed to the ciliary band and ciliary cover formation. |
