Cuticle surface contact is required for recognition of prey versus kin. Fluorescently labelled larval nematodes are P. pacificus carrying an egl-20::RFP marker to differentiate them from the unlabeled P. exspectatus larvae. The adult animal is a P. pacificus Eu mouth form predator. The P. pacificus predator makes nose contact with P. pacificus RFP tagged larvae which are kin and does not react whereas nose contact with untagged P. exspectatus larvae results in an immediate killing and feeding response.
