Behavior

Kinorhynchs are relatively abundant representatives of the permanent meiofauna, occasionally ranking third or fourth in number within a meiobenthic sample. The mean annual population density is about 10,000 -15,000, but may reach 50,000 specimens per square meter. Sex ratio in the populations is about 1:1.

Being placed into sedimented particles, kinorhynchs can agglutinate the detritus and amass the particles into concretions glued together by mucus. As also noted for nematodes, these activities result in soft bottoms acquiring a particular framework.

Parasitic Suctoria and sessile Peritricha infusorians (Cilio-phora) are often found on the trunk surface of kinorhynchs.
