Setting the pace: new insights into central pattern generator interactions in box jellyfish swimming. [PDF]
Central Pattern Generators (CPGs) produce rhythmic behaviour across all animal phyla. Cnidarians, which have a radially symmetric nervous system and pacemaker centres in multiples of four, provide an interesting comparison to bilaterian animals for ...

New Records of Cubozoan and Scyphozoan Jellyfish from Sabah Waters, Malaysia [PDF]
Jellyfish play a vital role in the ocean’s ecosystem, acting as a nursery for young fishes, crabs, and brittle stars, as well as a source of food for certain charismatic megafauna, such as sunfish and sea turtles.

Calcium sulfate hemihydrate (bassanite) statoliths in the cubozoan Carybdea sp.
Abstract The chemistry and physical structure of statoliths of young cubozoan medusae (Carybdea sp.) were examined by X-ray spectroscopy (EDX) and X-ray powder diffractometry (XRD). These concretions, associated with sensory receptors, were found to consist of bassanite (calcium sulfate hemihydrate), a dense but hygroscopic biomineral.

Eye Development in the Cubozoan Jellyfish Carybdea Marsupialis
Cnidarians are the most primitive invertebrates alive today to possess eyes. The complex eyes of the cubozoan jellyfish Carybdea marsupialis exhibit many similarities to the camera-type eyes of higher metazoans including the presence of a cornea, lens, and retina of ciliated photoreceptors. It is these similarities that make understanding the evolution

The anti-neural role of BMP signaling is a consequence of its ancestral function in dorsoventral patterning. [PDF]
In Bilateria with centralized nervous systems (e.g., in vertebrates or arthropods), the minimum of the BMP signaling activity gradient defines the position of the central nervous system.

Use of eDNA to Determine Source Locations of Deadly Jellyfish (Cubozoa) in an Open Coastal System [PDF]
Challenges associated with cubozoan jellyfish detection and the limitations of current detection techniques limit the ability of scientists to fill critical knowledge gaps surrounding their ecology. Environmental DNA (eDNA), however, has proven useful as

Swim pacemaker response to bath applied neurotransmitters in the cubozoan Tripedalia cystophora
The four rhopalia of cubomedusae are integrated parts of the central nervous system carrying their many eyes and thought to be the centres of visual information processing. Rhopalial pacemakers control locomotion through a complex neural signal transmitted to the ring nerve and the signal frequency is modulated by the visual input.

Cubozoan venom-induced cardiovascular collapse is caused by hyperkalemia and prevented by zinc gluconate in mice. [PDF]
Chironex fleckeri (Australian box jellyfish) stings can cause acute cardiovascular collapse and death. We developed methods to recover venom with high specific activity, and evaluated the effects of both total venom and constituent porins at doses ...

Cnidarian envenomations are the leading cause of severe and lethal human sting injuries from marine life. The total amount of venom discharged into sting-site tissues, sometimes referred to as “venom load”, has been previously shown to correlate with ...

Statolith morphometrics as a tool to distinguish among populations of three cubozoan species
Little is known on cubomedusae population structure, and what is known for many species is mostly from rare occurrences or from a metapopulation perspective. Knowledge on population units is critical for understanding population dynamics as well as predicting potential risk to swimmers.
