Distinguishing features

A large jellyfish with a pink/purple bell with a broad dark margin and small, scattered dark patches; numerous dense narrow pink tentacles.


  • Up to 40 cm (estimated bell diameter)
  • Up to 100 cm (reported bell diameter for this genus)



Local abundance

  • Lizard Island: Usually absent from this area. At least two individuals with broad brown bell margins were seen in Jan 2019, at the same time as several individuals of Cyanea sp. 1 (which has an evenly grey/white bell) were also reported. It seems odd that two similar and rare species should appear at the same time, so maybe it's a single variable species.
