Cephalodella catellina Mueller 1786
Cephalodella catellina, lateral view, showing the very short toes and the characteristic fold on the back. (3)
Cephalodella catellina, another specimen from (1), lateral view, showing the appendage of the tail above the foot.
Cephalodella catellina, another specimen from (1); view from the front with two eyespots and a common, single lens.
Cephalodella catellina, the manubrium (Ma) features a loop which is closed in contrast to C. catellina major. (2)
While the predatory rotifer Asplanchna normally feeds on smaller rotifers in this case it is vice versa: the bigger Asplanchna is trapped under the cover slide and cannot escape, while the smaller Cephadelodella can still move and picks the cuticula of Asplanchna, but is not capable of destroying the tough tissue.

Cephalodella catellina, male specimen. (4)
Cephalodella catellina, male specimen, dorsoventral view. (4)
Cephalodella catellina, another specimen from (1) together with Paramecium caudatum. (12/2010). While both organisms are about the same size Paramecium accomplishes all vital functions in a single cell. The rotifer Cephalodella has about 1000 cells, which therefore are much smaller than in Paramecium and are partly fused into a syncytium.
Another variety of C. catellina is C. catellina volvocicola
