Glomerula piloseta, longitudinal section of the tube

Glomerula is a genus of polychaete worm in the family Sabellidae. It differs from all other Sabellidae in having a calcareous tube and spinose setae. Only one living species, G. piloseta, is known from Lizard Island, Great Barrier Reef, Australia. [2] The oldest fossils of Glomerula are known from the Early Jurassic[1] and their tube microstructure has remained unchanged since then.[3]

Glomerula ( холандски; фламански )

добавил wikipedia NL

Glomerula is een geslacht van wormen, dat leefde van het Vroeg-Jura tot het Paleoceen.

Beschrijving

De dikwandige, buisvormige kokertjes van deze kokerworm hadden een vrij kleine opening. Doordat de kokers van verschillende individuen verstrengeld raakten, leek de hele groep uiteindelijk op een slordig opgerold bolletje van losse eindjes touw. Daarom was het niet nodig om als groep aan de zeebodem verankerd te zijn. Het geslacht filterde het voedsel, dat bestond uit organische partikels en plankton, uit het zeewater.

Glomerula纓鰓蟲科下的一,為群生動物,大量的單體組成一個群體,不同單體間窄小的圓形體管互相交錯纏繞且毫無規則地生長,單體互相纏繞的習性使其得以自由而無須附著在海床上。與體管的厚壁相比,孔眼顯得非常窄小。牠們像多數纓鰓蟲科成員一樣,利用過濾海水中的浮游生物有機物維生。[2]本屬唯一的現生種──Glomerula piloseta,是在澳大利亞大堡礁蜥蜴島英语Lizard Island National Park發現的。[3]

ten Hove & Kupriyanova (2009) state that "According to Ippolitov (2007: 260), the name Glomerula Nielsen, 1931 should be “unavailable according to ICZN 13.3)”. No further explanation is given by Ippolitov. If he is referring to Article 13 (iii), the full text of that is: “Article 13. Names published after 1930.- (a) Names in general.- In addition to satisfying the provisions of Article 11, a name published after 1930 must be either . . . (iii) proposed expressly as a replacement fro a pre-existing available name”. Nielsen (1931: 85) defines the genus Glomerula in a key, and (p. 88) attributes a single species (Serpulites gordialis von Schlotheim, 1820) to his genus. Nielsen, who did not give any explanation for his action at all, either replaced the generic name Serpulites, a name explicitly unavailable according to “Article 20. Genus-group names ending in –ites . . . given to fossils.”, or he simply placed the species gordialis in a new genus. Both ways we do not see conflict with the Code, certainly not with 13 (iii), and in our opinion the name Glomerula is available, though not being a serpulid."
