Golenkinia radiata

I have found Golenkinia radiata so far exclusively in the Simmelried. Mostly the specimens are “stuck” there in floating algae with detritus, bacteria and filamentous algae. Therefore the bristles do not seem to serve as floating extensions, but seem to me rather to function as a feeding protection.
