Mechanisms of sulphide tolerance in the peanut worm, Sipunculus nudus (Sipunculidae) and in the lugworm, Arenicola marina (Polychaeta)

The peanut worm Sipunculus nudus and the lugworm Arenicola marina are inhabitants of intertidal flats. Both species may be exposed to H sub(2)S within their habitat. When oxygen is available, both species oxidize sulphide to thiosulphate, but in A. marina) this capability is more pronounced than in...

Description
Summary:The peanut worm Sipunculus nudus and the lugworm Arenicola marina are inhabitants of intertidal flats. Both species may be exposed to H sub(2)S within their habitat. When oxygen is available, both species oxidize sulphide to thiosulphate, but in A. marina) this capability is more pronounced than in S. nudus . If sulphide is not completely oxidized internally both intertidal worms switch to an anaerobic metabolism as indicated by the accumulation of opines and succinate.
