Rotaria rotatoria Pallas, 1766
Rotaria rotatoria: habitus while whirling; the whole animal is pretty slender, no distinct humps, with long foot.
Rotaria rotatoria: creeping movement
Rotaria rotatoria: dorsal view of the head, whirling. Focus plane on the red eyespots of the rostrum
Rotaria rotatoria: if, while whirling, particles which are too big get into the vortex of the corona or if other organisms like nematods are beating nearby the corona and rostrum are retracted. Some seconds later the rostrum starts coming out and testing using the cilia if the danger is over. Lateral view with focus on the dorsal antenna and the rostrum. The cilia of the still retracted trochal discs are visible.
Rotaria rotatoria: another specimen (4.4.2012, Haspelmoor, Bavaria) while whirling, lateral view. The algae which is in the vortex of the trochal discs is Synura sphagnicola
Rotaria rotatoria; rostrum with divided lamella and two red eyespots
Rotaria rotatoria, rostrum with cilia. The cilia have probably sensory functions.
Rotaria rotatoria; focus on the retractable foot which acts like a telescope
Rotaria rotatoria , foot with spurs (s) and 3 toes (Z). The number of toes is important for the identification of the different bdelloid genera.
