General: Pair of rounded, swimming nectophores brilliant blue in color, especially when illuminated with white light. Siphonosome frail and lacks bracts. Gastrozooids bright carmine red. Thin tentilla have a single terminal filament.
Habitat description: Mesopelagic.
Published depth range: 357 - 520 m
Color: Brilliant glowing blue.
Looks like: Desmophyes haematogaster
Key visual features: While both G. lapislazula and D. haematogaster have rounded nectophores and red-pigmented gastrozooids, D. haematogaster can be distinguished by presence of bracts, disjunct pedicular canal, and a substantial portion of the somatocyst remains in contact with the upper wall of the hydroecium.
