Rotaria neptunoida, creeping. (1)
Rotaria neptunoida, whirling (Gevelsberg, GruKlaZi, 3.6.2006) (2)
Rotaria neptunoida, focal plane on the foot with the bendable spurs (Sp) and toes. The ventral toes (vT) are much longer than the dorsal toes (dT). (3.6.2006) (2)
Rotaria neptunoida, the triangles show the extreme long footglands (27.07.2007)
Rotaria neptunoida, three stages of movement (1)
Rotaria neptunoida, head. Two eyespots on the rostrum. The lamella is single-lobed without notch. The arrows point to the retracted trochal discs. (1)
Rotaria neptunoida, rostrum while creeping from a specimen from (5). Left: focus plane on the cilia of the rostrum. Right image: two papillae (arrows) with ?sensory? cilia/ bristles which are permanetely in movement. Often the pigment of the red eyespots in the rostrum seems to "dissolve" in Rotaria species.
 
Rotaria neptunoida, Foot with toes. (1)
Rotaria neptunoida, trophi in cephalic view. Dental formula 2/2. (4)
Rotaria neptunoida, trophi in caudal view. The rami apophysis become visible (arrowheads). This can help to distinguihs R. neptunoida from R. tardigrada where the rami apophysis are lacking. (4)
