Rapid scavenging of jellyfish carcasses reveals the importance of gelatinous material to deep-sea food webs.
Jellyfish blooms are common in many oceans, and anthropogenic changes appear to have increased their magnitude in some regions. Although mass falls of jellyfish carcasses have been observed recently at the deep seafloor, the dense necrophage aggregations and rapid consumption rates typical for vertebrate carrion have not been documented. This has led to a paradigm of limited energy transfer to ...
متن کاملMass deposition of jellyfish in the deep Arabian Sea
In December 2002, large numbers of dead jellyfish, Crambionella orsini, were observed on the seabed over a wide area of the Arabian Sea off the coast of Oman at depths between 300 m and 3,300 m. Moribund jellyfish were seen tumbling down the continental slope. Large aggregations of dead jellyfish were evident within canyons and on the continental rise. At the deepest stations, patches of rottin...
متن کاملJelly biomass sinking speed reveals a fast carbon export mechanism
Sinking of gelatinous zooplankton biomass is an important component of the biological pump removing carbon from the upper ocean. The export efficiency, e.g., how much biomass reaches the ocean interior sequestering carbon, is poorly known because of the absence of reliable sinking speed data. We measured sinking rates of gelatinous particulate organic matter (jelly-POM) from different species o...
متن کاملThe jellyfish joyride: causes, consequences and management responses to a more gelatinous future.
Human-induced stresses of overfishing, eutrophication, climate change, translocation and habitat modification appear to be promoting jellyfish (pelagic cnidarian and ctenophore) blooms to the detriment of other marine organisms. Mounting evidence suggests that the structure of pelagic ecosystems can change rapidly from one that is dominated by fish (that keep jellyfish in check through competit...
متن کاملCharacterization and Pharmacological Activities of Jellyfish, Chrysaora hysoscella Captured in Bushehr Port, Iran
Background: Cutaneous reactions like pruritus and erythema are common in warm months of the year in Bushehr Port, Persian Gulf, Iran due to jellyfish envenomation. This study reports isolation of the Chrysaora hysoscella nematocysts and evaluating its pharmacological activities during a bloom in 2013. Methods: The venom of C. hysoscella captured in Jofre area in Bushehr port was analyzed. Th...
