SHORT COMMUNICATION Salinity effects on asexual reproduction of Carybdea sp. (Cnidaria: Cubozoa)
نویسندگان
چکیده
Medusa production in cubozoans may be associated with reduced-salinity waters. Asexual reproduction of Carybdea sp. differed at different salinities. The metamorphosis of Carybdea sp. polyps into medusae was accelerated at low salinity (32), while more polyps were budded from the original polyp at the highest salinity (38), probably due to prolonged metamorphosis. High-nutrient river discharge may provide favorable conditions for Carybdea sp. blooms.

Carybdea marsupialis (Cubozoa) in the Mediterranean Sea: the first case of a sting causing cutaneous and systemic manifestations.
A woman stung by the box jellyfish Carybdea marsupialis (Cnidaria, Cubozoa) at a Spanish Mediterranean beach showed systemic manifestations over several months [pain far from the inoculation point, arthralgia, paresthesia, hyperesthesia, increase in eosinophils and immunoglobulin E (IgE)] in addition to the skin condition.

Here we establish a neotype for Alatina alata (Reynaud, 1830) from the Dutch Caribbean island of Bonaire. The species was originally described one hundred and eighty three years ago as Carybdea alata in La Centurie Zoologique-a monograph published by René Primevère Lesson during the age of worldwide scientific exploration. While monitoring monthly reproductive swarms of A. alata medusae in Bona...

Jellyfish blooms cause important ecological and socio-economic problems. Among jellyfish, cubozoans are infamous for their painful, sometimes deadly, stings and are a major public concern in tropical to subtropical areas; however, there is little information about the possible causes of their outbreaks. After a bloom of the cubomedusa Carybdea marsupialis (Carybdeidae) along the coast of Denia ...

Thermal and Osmotic Tolerance of ‘Irukandji’ Polyps: Cubozoa; Carukia barnesi
This research explores the thermal and osmotic tolerance of the polyp stage of the Irukandji jellyfish Carukia barnesi, which provides new insights into potential polyp habitat suitability. The research also targets temperature, salinity, feeding frequency, and combinations thereof, as cues for synchronous medusae production. Primary findings revealed 100% survivorship in osmotic treatments bet...
