The secretion and development of nematocysts in a siphonophore
Journal of Cell Science, 1973ABSTRACT Nematocyst development was watched in living cells of a siphonophore, Rosacea cymbiformis. The secretion differentiates in the formative cell into an ovoid capsule, continuous with a long apical tube. The entry of this ‘external’ tube into the capsule creates the coiled internal’ thread’ of the mature nematocyst.

Localization of bioluminescence in the siphonophore Nanomia cara
Marine Biology, 1987The base of the tentacle of the developing physonect larva (Nanomia cara) has a bioluminescent region. The ability to produce light in the larva is transitory; this ability first appears at about two days of development and is disappearing by eight days, as the larva begins to feed.
