In addition, when following the trail of a preferred snail, W. ![]() ![]() They rely on mucus trails to follow their preferred prey, but do not distinguish between snails of a preferred size by their mucus trails. laevis can use waterborne odors to detect the existence of prey. laevis only followed the trails of the thiarid snails, ear pond snails and tadpole snails, and did not show a different response to the trails produced by snails of different sizes. However, they follow the snails by their mucus trails, and not by the odor that the snails leave in the water. laevis has the chemosensory ability to detect the waterborne odors of snails. Five sympatric snail species, i.e., apple snail Pomacea canaliculata, thiarid snail Thiara tuberculata, viviparid snail Sinotaia quadrata, ear pond snail Radix auricularia swinhoei and tadpole snail Physa acuta were used as prey. In this study, we investigated the chemosensory ability for prey-detecting and searching in Whitmania laevis, a hirudiniformes species that mainly preys on freshwater snails, and examined if such ability aided in their prey selection. Although prey-detecting and searching abilities of predatory leeches of rhynchobdellid or the Erpobdelliformes of arhynchobdellid species have been studied in the past, hirudiniformes leeches are rarely mentioned.
