The White-spotted Jellyfish is easily recognised by the large, semi-transparent, rounded bell covered in regularly spaced, white dots. The trailing tentacles also end in whitened spots.
White-spotted Jellyfish are found throughout Australia.
White-spotted Jellyfish live in oceans and coastal waters.
The White-spotted Jellyfish is causing a problem overseas, particularly in the Caribbean region. It may have hitched a ride in ships' ballast tanks, travelling from Australia and the Pacific region to the Caribbean. Here, it found an ideal place to breed, free of their natural predators (various Pacific-region snails).
