Observations on the role of dissolved organic compounds in the nutrition of benthic invertebrates

Abstract
New observations on uptake of 14G labelled amino acids, glucose, and fatty acids by polychaetes and an echinoderm from the same habitats as pogonophores are compared with results already published for uptake by the pogonophores. Comparison is also made with new and published data on uptake by estuarine polychaetes. There is no great difference between the pogonophores ar_d the other animals in the maximum rate of uptake found per unit weight per hour, but the pogonophores seem better adapted to take up from lower external concentrations.
