Winds and currents have brought together all these jellyfish into shallow water. Now, when the sea-level has subsided they lie marooned on the drained beach. Because jellyfish are composed of up to 95% water, the strong summer sun will dry them out almost completely and almost obliterate any traces of them. |
There are many different factors that affect the numbers
and concentration within a given area. Physical and chemical conditions
such as temperature and salt
content can influence survival and growth through the different development
stages of the jellyfish. Biological factors such as predation, rivalry
and food resources are also important factors. It is rarely known what
factors have contributed the most when jellyfish appear in large populations.
