    Morphology and Anatomy:

    Frontal view of Fictor sp. showimg opposing dorsal teeth and serrated plates  for predatory feeding.

    From Susoy et al., 2015
    •  Cuticle with transverse striations, punctated or non-punctated, faint longitudinal lines or prominent longitudinal ridges; amphidial apertures ovoid.
    • Stoma monomorphic or dimorphic, Cheilostom composed of narrow plate-like rugae. Gymnostom a cuticular ring. Claw-like dorsal and right subventral teeth opposite left subventral serrated plates.
    • Pharynx with anterior procorpus; a strongly muscular metacorpus; a short, narrow isthmus and a glandular, rounded to oval terminal bulb.  

     Females:

    • Didelphic, amphidelphic with dorsally reflexed ovaries; short, narrow oviducts; spermathecae with sperms
    • Vulva equatorial or pre-equatorial, elliptical with or without protruded lips; phasmids located at middle of the conoid part of tail.
    • Tail with short conoid anterior part and long filiform posterior part.

    Distribution:

    Usually in organically-enriched habitats, with most species recorded from dung, compost, manure, rotten wood and decaying leaves. However, some of the species were also reported from humus, soil and sewage (Manhoub and Tahseen, 2022).

    Feeding:

    Food Sources and Feeding strategies for the genus Fictor

    Generally considered to feed as omnivores on bacteria, fungal hyphae and ciliates. and as predators on other nematodes by teareing into the cuticl;e with hooked dorsal tooth. (Mahboob and Tahseen, 2022)
