Extract

The tunicate heart has been extensively studied, with particular recent emphasis on the physiology of heart reversal (see Krijgsman (1956) and Kriebel (1968) for reviews). The salp heart, however, has received much less attention (Schultze, 1901; Nicolai, 1908), mainly because of the difficulty of maintaining this delicate marine animal in the laboratory. Thus the structure and function of the salp heart has been assumed to be similar to that of the sessile tunicates (Ihle, 1935; Berrill, 1950).
