Observations on the life histories of the narcomedusae Aeginura grimaldii, Cunina peregrina and Solmissus incisa from the western North Atlantic

Marine Biology, 2009
In this paper, we present evidence of direct development life cycles and brooding behaviour in two narcomedusae species in the family Cuninidae, as well as a histological description of another narcomedusan species from the family Aeginidae. Cunina peregrina were found to be brooding juveniles within the subumbrella.

Novel cnidocysts of narcomedusae and a medusivorous ctenophore, and confirmation of kleptocnidism

Tissue and Cell, 1989
Cnidocysts have been examined from the tentacles of the ctenophore Haeckelia rubra (Euchlora rubra) and five species of hydrozoan narcomedusae (Solmundella bitentaculata, Aegina citrea, Solmissus marshalli, Solmissus albescens, and Cunina sp.) using TEM, both in sections and by firing whole cnidocysts onto EM grids.

Resolution of fine biological structure including small narcomedusae across a front in the Southern California Bight

Journal of Geophysical Research, 2012
We sampled a front detected by SST gradient, ocean color imagery, and a Spray glider south of San Nicolas Island in the Southern California Bight between 14 and 18 October 2010. We sampled the front with an unusually extensive array of instrumentation, including the Continuous Underway Fish Egg Sampler (CUFES), the undulating In Situ Ichthyoplankton ...

Csiromedusa medeopolis: a remarkable Tasmanian medusa (Cnidaria: Hydrozoa: Narcomedusae) comprising a new family, genus and species

Zootaxa, 2010
An unusual new species of narcomedusa from Tasmania is described. It differs from all other species of narcomedusae in having two whorls of tentacles, as well as a beveled opening in the apical surface containing peculiar ‘sky-scraper-like’ protruding structures, which we have interpreted as gonads.

In SituForaging and Feeding Behaviour of Narcomedusae (Cnidaria: Hydrozoa)

Journal of the Marine Biological Association of the United Kingdom, 1989
Narcomedusae are a small and mostly oceanic group of hydromedusae whose tentacle morphology and comportment sets them off behaviourally and perhaps ecologically from most other medusae. Their tentacles are relatively few in number (2–40), stiff, and noncontractile, with points of insertion located well above the bell margin. Eleven species representing

Bathykorus bouilloni: a new genus and species of deep-sea jellyfish from the Arctic Ocean (Hydrozoa, Narcomedusae, Aeginidae)

Zootaxa, 2010
A new genus and species of a common deep-water narcomedusa is described from the Arctic Ocean. The species has four primary tentacles, four secondary tentacles, with three interradial manubrial pouches in each quadrant. A revision and taxonomic key of the family Aeginidae is presented to account for the new genus. Detailed information on its fine-scale

Foraging, prey capture, and gut contents of the mesopelagic narcomedusa Solmissus spp. (Cnidaria: Hydrozoa)

Marine Biology, 2002
Narcomedusae are the most common group of medusae in the mesopelagic depths of Monterey Bay, California. Numerous capture events of various prey taxa were recorded in situ and analyzed using the Monterey Bay Aquarium Research Institute's remotely operated vehicle "Ventana".
