Poeobius ( Inglês )

fornecido por wikipedia EN

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

The 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]

Poeobius meseres ( Neerlandês; Flamengo )

fornecido por wikipedia NL

Poeobius meseres is een borstelworm uit de familie Poeobiidae. Het lichaam van de worm bestaat uit een kop, een cilindrisch, gesegmenteerd lichaam en een staartstukje. De kop bestaat uit een prostomium (gedeelte voor de mondopening) en een peristomium (gedeelte rond de mond) en draagt gepaarde aanhangsels (palpen, antennen en cirri).

Poeobius meseres werd in 1930 voor het eerst wetenschappelijk beschreven door Heath.

ウキナガムシ (Poeobius meseres) は多毛類の一種である。

形態[編集]

全長は最大27mm。体は透明で、ゼラチン質の鞘に包まれている[1]。体節は不明瞭で、疣足、剛毛を持たない。[2]

生態[編集]

太平洋東部の深海に生息する[1]モンテレー湾でのビデオカメラを用いた調査では、深度1800m前後の浮遊性動物の大部分が本種で構成されていた[3]

餌は主にオキアミ・カイアシ類の糞であるが、珪藻も食べる。頭部の触手で餌粒子を集める、または、分泌した粘液で餌粒子を絡め取るという2種類の摂餌方法を持つ[4]

分類[編集]

分子系統解析によって、本種は底生のハボウキゴカイ科から進化したことが示されている[1]

Enigma terwillei は本種に近縁だと考えられているが、タイプ標本が失われているため詳細は不明である[1]
