Some peculiar contacts concerning a picked unique of Brachionus and other swimming rotifers ended up noticed. It appears like the connected rotifer seeks for call with other people with the aid of its sensitive corona. The responding rotifers position their anus-foot back again region on its corona and preserve call for some time. The explanation of the phenomenon is unidentified (at least to me).
