Abstract Studies on the nutritional transport of holothurians have failed to delineate the role of the amoebocytes as well as the haemal system in this function. Autoradiographic studies have been carried out on tissues of animals injected with 14C glucose in order to localise the incorporation of the labelled sugar in tissues such as the alimentary canal, haemal system, respiratory tree and the body wall. In all tissues the amoebocytes were clearly labelled, indicating a key role in the transportation of sugars. Furthermore, it has been shown that sugar also enters the tissues by diffusion. It is interesting that the haemal system appears to transport glucose more rapidly than other tissues as indicated by the heavy labelling.
