Adineta tuberculosa Janson 1893
Adineta tuberculosa, ventral view of a creeping/ feeding animal, focal plane on the wart-like integument, which covers the whole animal in this morphotype. This is in contrast to the original description of Janson (1893) whose specimens had no granulations of the integument of the foot. This is also in contrast to the morphotype Adineta sp. 4, where the integument of the trunk has no conspicuous granulations (and the NoUH is different).
Adineta tuberculosa, while "swimming" the body is contracted.
Adineta tuberculosa, another specimen.
