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.
Nomura’s jellyfish are normally found in the Yellow Sea and populations are generally maintained there year round. During June and July, changes in the water salinity lead to the expatriation of larval stage jellyfish via the Tsushima strait. In 2005 the largest blooms were in late October. [5]
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.
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 ]

The jellyfish-like creature is a floating colonial coelenterate with a number of polyps and a conspicuous float. Beachgoers should avoid them because, like a jellyfish, they have tentacles that ...
Now, the mystery is solved: it is a placental jellyfish -- after many. For two years a mysterious sea creature has been captured on video as it swims 5,000 feet below the surface, but scientists ...
Jellyfish, starfish, sand dollars and the occasional octopus wash up on South Carolina beaches all year round. For these invertebrates, sitting exposed to the sun and air will eventually kill them.
