A jellyfish bloom is defined as a substantial increase in a jellyfish population within a short time period; the result of a higher reproduction rate. [2] Since jellyfish naturally have high reproductive rates, high-density blooms can occur as a result of both behavioral and ecological causes.
The sting of all Irukandji Jellyfish is believed to cause Irukandji Syndrome and can be potentially fatal, however the sting of the Malo maxima is the most dangerous of the Malo species. Only two types of species have the venom to cause Irukandji syndrome, the Irukandji Jellyfish and the Box Jelly. The Box Jelly is extremely more venomous than ...
Catostylus mosaicus is also known as the jelly blubber or blue blubber jellyfish. [1] The jelly blubber is distinguishable by its color, which ranges from light blue to a dark blue or purple, and its large (250-300mm [ 2 ] ), rounded bell which pulses in a staccato rhythm. [ 1 ]
Jellyfish blooms can have significant impact on community structure. Some carnivorous jellyfish species prey on zooplankton while others graze on primary producers. [110] Reductions in zooplankton and ichthyoplankton due to a jellyfish bloom can ripple through the trophic levels.
The potential worsening of jellyfish blooms as a result of human activities has driven new research into the influence of dead zones on jelly populations. The primary concern is the potential for dead zones to serve as breeding grounds for jelly populations as a result of the hypoxic conditions driving away competition for resources and common ...
Cyanea nozakii or Cyanea nozaki (misspelling), commonly known as the ghost jellyfish, is a species of jellyfish found in the northern Pacific Ocean near the coasts of China and Japan. Along with other species of large jellyfish, it is showing a greater tendency to appear in large numbers and cause blooms.
No single cause identified for the thousands of crustaceans washed up on beaches last year but algal bloom is thought to be ‘significant’. Harmful algal bloom ‘most likely cause’ of North ...
Blooms of jellyfish may also impact economic stability in surrounding communities, due to overfishing which alters trophic processes. [11] As jellyfish overpopulate ecosystems, they may wipe out large numbers of fish in their habitat. Blooms occur because of changes in temperature and phytoplankton abundance in the ecosystem. [11]
