Australian aquarists have rediscovered a jellyfish that hasn't been seen for more than 100 years.



The last spotting of the rare, toxic Crambione Cookii was in 1910.

Puk Scivyer, from the UnderWater World aquarium in Mooloolaba, said they found the jellyfish during an operation to release a turtle off Queensland.



"As soon as I saw it I realised it was a species I'd never seen before. But to then discover I was the first person to see this species in over a hundred years was just incredible.''
