Pectinatella magnifica, the magnificent bryozoan, is a member of the Bryozoa phylum, in the order Plumatellida. It is a colony of organisms that bind together; these colonies can sometimes be 60 centimeters in diameter. These organisms can be found mostly in North America with some in Europe. They are often found attached to objects, but can be found free floating as well. They form a translucent body with many star-like blooms along the outside. The density of the organism is similar to that of gelatin, and is easily breakable into smaller chunks (Wikipedia contributors 2018).
Status and distribution in Luxembourg
In 2012 numerous colonies of Pectinatella magnifica (Leidy, 1851) (Bryozoa, Phylactolaemata) were discovered in the reservoir of Esch-sur-Sûre (Luxembourg) fed by the river Sûre. The colonies were particularly abundant in the shallow, warm and nutrient-rich water near the riverbank, but some colonies were spotted by divers in the reservoir at a depth of 8-9 m in one site and more than 20 m in another site. There is reliable evidence that Pectinatella was present, but less conspicuous and as such not identified, in 2011 and possibly already in 2010. P. magnifica was hitherto unrecorded in Luxembourg, but known from a site near the German-Luxembourg border near Nennig (Germany, Saarland) where statoblasts were found in 2001 (Massard et al. 2013).
Three records of the species are accessible through the MNHNL-mdata portal (MNHNL, iNaturalist & GBIF, 2021).
C1 (3+2+1+1) (Ries et al. 2017: 68).
