Abstract
A TROPICAL papyrus swamp is a difficult environment for animal life, the mud in which the swamp worms (Oligo-chaeta, Glossoscolecidae) live is both anaerobic and strongly reducing1. In order to obtain atmospheric oxygen in these conditions, the dorsal surface of the hind end of Alma is specially modified as a respiratory organ which is exposed above the surface of the mud1. It is quite likely that Alma is biochemically adapted to life in the swamp environment.
