Poeobius is a genus of marine polychaete worm. It contains the single species Poeobius meseres, or balloon worm.[1][2] This is a common and abundant resident in the midwater around the mesopelagic and bathypelagic zones, especially in Monterey Bay.[3] They can be found at around 300-2,500 m (980-8,200 ft) depth from Japan to Alaska to the Gulf of California, and have also been reported in South America.[3]

Description
editThe species is a passive detritivore, using a mucus net to capture marine snow as it hangs neutrally-buoyant midwater.[4] The gelatinous body consist of 11 poorly defined segments with no setae or external segmentation.[5] Only two septa remains, which divides the coelomic cavity into an anterior, middle and posterior coelom. There is no serial duplication of the internal organs.[6] They have a maximum size of 36 mm (1.5 in).[3]
