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.
This in turn kills fish and other animals, but not jellyfish, [94] allowing them to bloom. [95] [96] Jellyfish populations may be expanding globally as a result of land runoff and overfishing of their natural predators. [97] [98] Jellyfish are well placed to benefit from disturbance of marine ecosystems. They reproduce rapidly; they prey upon ...
Mayo Clinic states that most jellyfish stings, unless severe symptoms are also present, can be treated by: Carefully plucking visible tentacles from the skin with fine tweezers Soaking the skin in ...
Jellyfish are slow swimmers, and most species form part of the plankton. Traditionally jellyfish have been viewed as trophic dead ends, minor players in the marine food web, gelatinous organisms with a body plan largely based on water that offers little nutritional value or interest for other organisms apart from a few specialised predators such as the ocean sunfish and the leatherback sea turtle.
Chrysaora fuscescens, the Pacific sea nettle or West Coast sea nettle, is a widespread planktonic scyphozoan cnidarian—or medusa, "jellyfish" or "jelly"—that lives in the northeastern Pacific Ocean, in temperate to cooler waters off of British Columbia and the West Coast of the United States, ranging south to México.

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.
