On the nematocysts of hydromedusae [PDF]
The nematocysts of twenty species of Hydromedusae occurring at Plymouth are described. Of these, twelve were Anthomedusae and seven were Leptomedusae, and one was the Siphonophore, Muggiaea atlantica. The medusae fit very well into the generally accepted classification as regards the types of nematocysts they possess.

Diversity and evolution of myxozoan minicollagens and nematogalectins [PDF]
Background: Myxozoa are a diverse group of metazoan parasites with a very simple organization, which has for decades eluded their evolutionary origin. Their most prominent and characteristic feature is the polar capsule: a complex intracellular structure

Marine and other aquatic dermatoses
Occupational and recreational aquatic activity predisposes our population to a wide variety of dermatoses. Sunburn, urticaria, jellyfish stings, and contact dermatitis to rubber equipment are common allergies that are encountered in the aquatic ...

The nematocysts of Microstoma are derived from Hydra upon which Microstoma feeds. These ingested nematocysts are delivered to the mesoderm by the endoderm of the flatworm. Within the mesoderm an amœboid cell takes charge of each nematocyst and as it is transported to the surface orients it so that the "sting-thread" has its discharging pole directed ...

Prey Resource Utilization by Coexistent Hydromedusae from Friday Harbor, Washington, USA [PDF]
Prey selection patterns were quantified for a sympatric group of hydromedusae from Friday Harbor, WA. Selection patterns varied between species, but were largely replicable between sample dates and resembled dietary patterns found in similar studies from

Preserved specimens make it difficult to study nematocysts. We tested an hydration protocol on ethanol preserved tentacles of Chiropsalmus quadrumanus (Cubomedusae) during a period of ten days, and quantified the success of retrieval of information ...

Granulocytes of sea anemone Actinia equina (Linnaeus, 1758) body fluid contain and release cytolysins forming plaques of lysis [PDF]
The Cnidaria phylum includes organisms that are among the most poisonous animals. The exact composition of cnidarian bioactive molecules is not known in detail, but little is known on the cells that produce the toxins.

Effects of cnidarian biofouling on salmon gill health and development of amoebic gill disease.
This study examines the potential implications of biofouling management on the development of an infectious disease in Norwegian farmed salmon. The hydroid Ectopleura larynx frequently colonises cage nets at high densities (thousands of colonies per m2 ...
