Composition of organic matter in deep-sea holoturians and host bottom sediments from the Kuril-Kamchatka Trench
In 5 holothurian species of the Aspidochirota and Elasipoda orders concentration of organic carbon in alimentary canals due to selective feeding on the average is 7 times higher than in host sediments. Concentration decreases from the first section of the alimentary canal to the last. Intestinal con...
