| One of the largest jellyfish species (Ref. 3010). Occurrence of jellyfish bloom has threatened the fisheries in Japan since early 2000s, possibly because of global warming - note that the growth of medusae are dependent on high temperatures (Ref. 100320). Occurs in semi-enclosed basins of marginal seas (Ref. 122853) and also found offshore (Ref. 122855). Before the chitin-covered podocysts develop into adults, they remain dormant for at least 6 years. Jellyfish blooms occur by mass excystment of these podocysts upon exposure to high temperatures (Ref. 100312). |
