Taxonomy
Kingdom:Animalia
Phylum:Cnidaria
Class: Hydrozoa
Order:Siphonophorae
Family:Diphyidae

Description
Polygastric phase: Anterior nectophore: 18 mm in length, smooth, devoid of ridges, with blunt apex and broad base. Nectosac large sub-cylindrical, slightly bent, with blunt apex and well developed musculature; all canals arise near baso-ventral corner of nectosac from pedicular canal; lateral canals connected by oblique commissural canal. Hydroecium absent. Somatocyst thin long, characteristically curved, reach up to middle of nectosac on dorsal side. Sub-ostial lamellae or mouth plate occur as two basolateral wings due to deep division between wings; inner margin of mouth plate thick and raised into oval shaped vertical pads. Reserve buds of anterior and posterior nectophores often present.

Posterior nectophore: Up to 19 mm long, sub-cylindrical in shape, with truncated broad apical end, smooth, devoid of any ridges. Nectosac with two characteristic constrictions at right angles to one another. Two dorsal and two lateral teeth present around ostium. Lateral radial canal form a long loop extending from base to apex before joining ring-canal. Mouth-plate, long, large occur as two baso-ventral wings with thickened vertical pads as in anterior nectophore. Hydroecium is a shallow open groove.

Stem: Long, bearing numerous (nearly 200) cormidia.

Eudoxid phase: Male and female gonophores borne on separate colonies. Manubrium of male gonophores-vermillion and female colorless.
