Gordius dimorphus larvae are similar to previous light microscope descriptions. One large spine is present on the posterior portion of the postseptum.
On the surface of each projection, 3 pairs of aculeiforms spines are aligned and lean toward the proboscis opening. Although nematomorphs make up only 1 of 3 animal phyla specializing solely on a parasitic life style, little attention has been focused on this enigmatic group scientifically. palustris De Man 1880, throughout its life cycle. The proboscis is retractile, dorsoventrally flattened, with 1 pair of forceps-like projections on its distal-most portion. Compared with most animal phyla, the Nematomorpha, also known as hair worms, is a relatively understudied metazoan phylum. its growth and reproduction rates within snail-sediment extract (cheap and locally available culturing. Three concentric rings with 6 spines each surround the proboscis. Larvae have a cylindrical body, annulated and divided into 2 sections, plus an anterior preseptum and a posterior postseptum. dimorphus (2 males and 1 female) were maintained under laboratory conditions until oviposition, which occurred within long strings commonly referred to as egg strings. Scanning electron microscopy was used to analyze superficial features of Gordius dimorphus Poinar, 1991, larvae that might serve as generic or specific diagnostic characters.
