Jellyfish blooms are substantial growths in population of species under the phyla Cnidaria (including several types of jellyfish) and Ctenophora (comb jellies). Blooms may take place naturally as a result of ocean and wind patterns, [ 1 ] ecosystem shifts, and jellyfish behaviors though their occurrence is thought to have increased during the ...
Large blooms of jellyfish in coastal areas can interrupt recreation and their arms may produce a mild but irritating sting. [16] Due to their size and high abundance, C. mosaicus is harvested for human consumption, and is considered a delicacy in some countries, including China and Japan.
The hypothesis is that the feature helps the jellyfish catch its prey of small fish. [7] Irukandji jellyfish have the ability to fire stingers from the tips of their tentacles and inject venom. [23] Irukandji jellyfish's stings are so severe they can cause fatal brain hemorrhages and on average send 50–100 people to the hospital annually. [24]
Dinoflagellates sometimes bloom in concentrations of more than a million cells per millilitre. Under such circumstances, they can produce toxins (generally called dinotoxins ) in quantities capable of killing fish and accumulating in filter feeders such as shellfish , which in turn may be passed on to people who eat them.
