Rotaria neptunia Ehrenberg, 1832
Rotaria neptunia, aggregation of several individuals on a decomposing leaf(1)
 
Rotaria neptunia, extended animal whirling. R. neptunia has the longest foot of all bdelloids, which can be retracted. This retractable foot enables R. neptunia to live in relative thick layers of mud compared to other bdelloid rotifers which have a shorter foot. (2)
 
Rotaria neptunia, this image of a contracted specimen demonstrates that the retracted foot reaches at least up to the mastax.
