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 jellyfish tree presents a conundrum in that the seeds seem unable to germinate in the wild; no young plants have been observed in the natural stands. [8] Successful cultivation in botanic gardens has occurred in very humid conditions, but high humidity is unlikely in the exposed habitat where these trees are found in the wild. [8]
During the day the medusae will attach themselves with the adhesive patches on their tentacles to various surfaces, especially seagrass, earning the species its common name clinging jellyfish. [ 2 ] [ 3 ] Gonionemus vertens may catch prey when attached to surfaces during the day, but they mostly feed at night in open water, [ 3 ] [ 4 ] eating ...
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.
Craspedacusta sowerbii or peach blossom jellyfish [1] is a species of freshwater hydrozoan jellyfish, or hydromedusa cnidarian. Hydromedusan jellyfish differ from scyphozoan jellyfish because they have a muscular, shelf-like structure called a velum on the ventral surface, attached to the bell margin.
Aequorea vitrina, commonly called the crystal jellyfish, crystal jelly, lampshade or disk jellyfish, [2] is a species of hydrozoan in the family Aequoreidae. [3] [4]The specific name vitrina means "glassy", due to its transparent appearance; it should not be confused with Aequorea victoria, which is also sometimes called the crystal jelly.
The aptly named immortal jellyfish (Turritopsis dohrnii) is one such animal — and, in a surprise discovery now published in Proceedings of the National Academy of Sciences, scientists have added ...
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.
