@touti, oui, il avait même l’accent du Midi…
La légende complète : c’est une expérience menée en 1963…
Figure 5: Platydemus manokwari de Beauchamp, 1963, experimental predation on indigenous snail.
The flatworm is preying on a snail: it has been disturbed, thus showing the white cylindrical pharynx on the ventral side, protruding and ingesting soft tissues of the snail. The prey is the helicid Eobania vermiculata, a common snail of the Mediterranean region.

Notons que 4 des 5 escargots n’ont pas eu la chance de participer activement à l’expérimentation…
Various living snails were introduced in the same container as a single flatworm. Four out of the 5 specimens died before feeding. A single prey event, on the helicid Eobania vermiculata Müller, 1774 was observed. The cylindrical pharynx, protruding from the ventral surface, was visible when the flatworm was preying on a snail (Fig. 5).
