Summary and conclusion The float gases of Physalia contain carbon monoxide. The amount varied from 0.21% to 6.07% of the total. It is suggested that variations in carbon monoxide content may reflect differing functional states in the organism. The composition of the gas in the pneumocyst may change qualitatively and quantitatively in 24 hours. When the float was inflated with pure carbon monoxide this gas was diluted approximately 4-fold during the following 66 hours. During this same period… 

Carbon Monoxide Production by a Bathypelagic Siphonophore

A physonectid siphonophore, Nanomia bijuga, associated with a verticallymigrating deep scattering layer, has been observed with a gasfilled float at depths in excess of 300 meters in the sea. This

Morphology and development of the Portuguese man of war, Physalia physalis

This work proposes a framework for homologizing the axes with other siphonophores, and suggests that the tentacle bearing zooids should be called tentacular palpons, and looks at live and fixed larval and non-reproductively mature juvenile specimens and uses optical projection tomography to build on existing knowledge about the morphology and development of this species.

Genesis of Hydrocarbons of Low Molecular Weight in Organic-Rich Aquatic Systems

Mild heat treatment of water-wet marine muds resulted in the genesis of three aromatic hydrocarbons characteristic of crude oils, but which are seldom found in significant quantities in recent


The study of P. physalis is very interesting, especially under the issue of climate change, because many scientists believe that jellyfish get benefit from increasing sea temperatures, so the population is predicted to increase.


The geographic distribution, anatomy, and physiology of Physalia physalis are reviewed. The mechanism of stinging is emphasized as the basis for the formation of characteristic cutaneous lesions and
