The spermatozoon of the jellyfish Nausithoë
Journal of Ultrastructure Research, 1971The spermatozoon of the primitive scyphomedusa Nausithoe has a short conical head, a midpiece containing four large mitochondria, and a long tail consisting of a flagellum. It is therefore a “primitive spermatozoon” as earlier defined. Some unusual structural features have been noted.

The flow induced by a jellyfish
Journal of Visualization, 2008The purpose of this study is to understand the propulsion mechanism of a jellyfish during its swimming. We observed the motion of a jellyfish (Aurelia aurita) by a motion-capture camera, and measured the vector field of flow around a jellyfish by using a PIV (Particle Image Velocimetry) measurement. A jellyfish is considered to be principally propelled

Jellyfish Model for Ototoxicity
Otology & Neurotology, 2015Pharmacologic ototoxicity is well described in the medical literature, yet efficient screening models are lacking. Aurelia aurita ephyrae, transparent jellyfish with identifiable hair cells, could be an effective model. Structural changes readily manifest behaviorally, and hair cells are easily stained and observed.

Granulomatous jellyfish dermatitis
JDDG: Journal der Deutschen Dermatologischen Gesellschaft, 2007SummaryThe induction of a granulomatous inflammation by jellyfish toxins is rare. More typically, acute toxic and urticarial reactions are seen. An 11‐year‐old boy developed a striated urticarial erythema on the left cheek after contact with a gelatinous mass while swimming in the sea in Croatia.

Our knowledge of animal and human physiological processes owes much to over a century of study of natural toxins. The neurotoxins of kraits (bungarotoxins from Bungarus spp.) and cobras (Naja spp.) have helped define the acetylcholine receptor and neuromuscular transmission.

Beware the malignant jellyfish
The Annals of Thoracic Surgery, 2001Small pleural effusions that cannot be assessed by thoracentesis prior to surgery may represent a diagnostic challenge in the patient with a resectable, non-small cell cancer of the lung. Even if the effusion is drained preoperatively and analyzed, the cytology may be falsely negative.

Nature Ecology & Evolution, 2019
Three studies presenting genomes and transcriptomes from different life stages of nearly all major lineages of medusozoans present radically different gene expression profiles between life cycle stages and many medusa-specific genes.
