L. luymesi does not posses a digestive system; rather, it acquires energy via internal sulfide-oxidizing bacterial symbionts [6]. L. luymesi differs from other vestimentiferan tubeworms by its ability to use a posterior extension of its body, the “root,” to acquire sulfide from interstitial pools in sediments [7,8]. Near the anterior plumes of tubeworms, sulfide concentrations typically decline below 0.1 μM as the tubeworms approach 1 m in length [9]. By using its roots, L. luymesi is able to delve into deeper sediment layers, providing access to more persistent sulfide sources. In the apparent absence of lethal predation [10,11], the most significant hazard that this vestimentiferan tubeworm faces is sulfide limitation. Its high uptake rate of sulfide from hydrocarbon seep sediments, estimated at over 30 μmol · h−1 for a moderate-sized individual [12], suggests that sulfide flux may be limiting in L. luymesi's habitat.","tracks":[{"project":"2_test","denotations":[{"id":"15736979-10441078-84746021","span":{"begin":549,"end":550},"obj":"10441078"},{"id":"T24656","span":{"begin":549,"end":550},"obj":"10441078"}],"attributes":[{"subj":"15736979-10441078-84746021","pred":"source","obj":"2_test"},{"subj":"T24656","pred":"source","obj":"2_test"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"2_test","color":"#93deec","default":true}]}]}}
