Abstract
As part of an attempt to assess the importance of organic solutes as a food source for benthic animals, the uptake of carboxylic and amino-acids by the polychaete worm Nereis virens has been investigated1. Previous investigations1–3 have been concerned chiefly with the adult animals and it has been shown that the absorption process is an active one. The ratio of surface area to body volume of the animal is of obvious importance in any absorption process and it has already been demonstrated that uptake is faster in smaller than in larger animals4. Larvae might therefore be expected to show a very considerably enhanced rate of uptake.
