Abyla haeckeli   Lens & van Riemsdijk,  1908 (Hydrozoan)
Organism information awaits expert curation
Class: Hydrozoa

Polygastric phase: Anterior nectophore: As wide as high, with flat facets, ridges not elevated, characterised by presence of horizontal ridge dividing apico-ventral facet into two-rectangular apico-ventral facet and a perfect pentagonal ventral facet(i.e. sides being almost equal in length). Horizontal ridges lying below mid-level of somatocyst.

Posterior nectophore: With only 2 or 3 comb-teeth; lateral teeth lie closer to large dorsal tooth than to ventral ones. Nectophores long and slender, hydroecial wings not expanded.

Eudoxid phase: Bract: Baso-ventral margin of hydroecium deeply concave instead of being straight, with a prominent basal tooth on right side and none on left side.

Gonophore: Broad, with five ostial teeth around ostium. Dorso-lateral ridges prominent lying beside flared out dorsal tooth. Ventral ridges not expanded into wings, with small teeth at edge and ending in two symmetrical teeth at base.
