Hitchhiking freshwater clams: First report of Sphaerium nucleus attached to Lissotriton helveticus in France

Résumé

Phoresy is a specific form of commensalism where a mobile organism affords transport to a less mobile one (White, Morran, & de Roode, 2017). Many phoretic associations have been described (Clausen, 1976; Binns, 1982; Bartlow & Agosta, 2021) of which several examples involve freshwater molluscs; presumably because they have limited ability to make long distance dispersal by themselves. Charles Darwin (1882) made pioneering observation of such dispersal in the freshwater mussel Unio complanatus attached to the toe of a duck, as well as supposedly Sphaerium corneum (then named Cyclas cornea) caught on the toes of newts (species not defined). Since then, multiple studies have reported phoretic associations between freshwater bivalves and lizards (Lopez et al., 2005), frogs and toads (Kolenda et al., 2017), and newts (Audibert et al., 2013). Among amphibians, newts appear to be often used as 'hosts' by freshwater mussels for two reasons. First, mussels can attach easily to the toes of newts whereas attaching to the skin folds of anurans is more difficult (Kolenda et al., 2017). Second, newt species may move between ponds during breeding season (Denoël et al., 2018) which would facilitate local
