The species has separate sexes and breeding occurs from March to September. It has a planktonic veliger larva. Longevity is believed to be four or five years. At constant food conditions growth is found to be partly correlated with temperature (Salzwedel, 1979).  
 T. fabula lives up to 10 cm deep in the sediment and lies in a more or less horizontal position on the left valve. lt is a selective deposit as well as a suspension feeder. lts feeding behaviour probably changes with age and season (Salzwedel, 1979; Fish & Fish, 1989).
