Japan - Introduced into Japan's temperate waters in 1921, the progeny of a mating pair of Nomura's Jellyfish are set to cause catastrophe in the Pacific Ring Of Fire's quake-hit zone.
Seismologists said today up to 10 million of the giant beasties have been swept up by the tsunami and are heading towards New Zealand.
The 8.9 quake has seen massive tsunamis capture the vast cnidaria swarm, spotted earlier last week in the Sea of Japan.
And now the quake's 30ft tidal surge is believed to be on a collision course with Christchurch, recently devastated by it's own deadly tremors.
Marine biologists monitoring events have confirmed that the 6ft, 200kg creatures were headed southwards in a deadly wall of water.
The aquatic giants were named after Fukui Prefectural Fisheries Experimental Station's former Director General Mr Kan'ichi Nomura.
He was the first to study them and subsequently introduced a pair into Japan's territorial waters 'as a bit of an experiment'.
ETA at Christchurch is midnight.
