Tentacle Musculature in the Cubozoan Jellyfish Carybdea marsupialis

The Biological Bulletin, 2018
The diploblastic cnidarian body plan comprising the epidermis and gastrodermis has remained largely unchanged since it evolved roughly 600 Ma. The origin of muscle from the mesoderm in triploblastic lineages is a central evolutionary question in higher animals.

Photoreceptors of cubozoan jellyfish

Hydrobiologia, 2004
The anatomically sophisticated visual system of the cubozoan jellyfish Carybdea marsupialis is described. Individual cubomedusae have eight complex eyes, each with a cornea, lens, and retina of ciliated photoreceptor cells, eight slit ocelli, and eight dimple ocelli.

Growth and age determination of the tropical Australian cubozoan Chiropsalmus sp

Hydrobiologia, 2004
Chiropsalmus sp. medusae collected in this study ranged from 3 to 71 mm diagonal bell width and displayed growth best described by the following equation size (mm) = 74.9 × exp (−exp(0.041 (time since metamorphosis (day) −35.6674))). Growth rates of up to 7 mm week−1 increase in diagonal bell width are theoretically possible, with animals able to reach

Observations on the anatomy and behaviour of the cubozoan Carybdea rastonii haacke

Marine and Freshwater Behaviour and Physiology, 1995
The cubozoan Carybdea rastonii occurs throughout the Pacific and is very abundant in areas of South Australia. C. rastonii has been observed feeding in the field on mysids and larval fish and on Anemia and fish in the laboratory. The medusae occur in swarms and are closely associated with sand patches during the day (but are not capable of attachment ...

Variation in soft tissue chemistry among scyphozoan and cubozoan jellyfishes from the Great Barrier Reef, Australia

, 2012
Bioaccumulation of trace elements in jellyfish has so far received little attention, despite their being prey for many animals from multiple trophic levels and targeted by commercial jellyfish fisheries.

Cubozoan Envenomations: Clinical Features, Pathophysiology and Management

2016
Cubozoa-class cnidarian (box jellyfish) envenomations constitute a complex medical challenge and public health threat. There are currently no validated standards of care for life-threatening stings. Increasing numbers and reported geographic ranges of serious cubozoan envenomations underscore the urgent need for mechanism-based emergency therapeutic ...

Muscle Organization of the Cubozoan JellyfishTripedalia cystophoraConant 1897

The Biological Bulletin, 2005
The musculature of the cubomedusa Tripedalia cystophora was investigated using immunohistochemical staining with an anti-actin antibody and histochemical staining with fluorescent phalloidin. The subumbrella is lined with a sheet of circular, striated muscle that is interrupted at the perradii, and by the nerve ring.

Arrangement of accessory cells and nematocytes bearing mastigophores in the tentacles of the cubozoan Chironex fleckeri

Journal of Morphology, 1988
AbstractNematocytes containing microbasic mastigophores are intimately associated with accessory cells in the epidermis of Chironex fleckeri. Large microbasic mastigophores may be surrounded by seven to nine such cells. Each accessory cell possesses an apical portion containing secretory droplets and a basal portion which carries a radially oriented ...

Cubozoan jellyfish envenomation syndromes and their medical treatment in northern Australia

Hydrobiologia, 1991
The stings of Chironex fleckeri, Carukia barnesi and two unidentified carybdeids cause severe or fatal symptoms to swimmers in tropical Australia. The cubozoans and their envenomation syndromes are described. First-aid and medical treatment are reviewed, and safety precautions to prevent envenomation are recommended.
