Scavenging and entomopathogenic nematodes
It has been demonstrated that an entomopathogenic nematode, Steinernema feltiae that only infect and kill their insect host but it can also be attracted to the cues released from the slug cadavers suggesting that entomopathogenic nematodes can feed on carcasses of other organisms (Nermut et al., 2012).
