Nomura's jellyfish
Encyclopedia
is a very large jellyfish
, in the same size class as the lion's mane jellyfish
, the largest cnidarian in the world. The diameter of one fully grown is slightly greater than the height of an average fully grown man. The species was named in tribute to Mr. Kan'ichi Nomura (C18–C19), Director General of the Fukui Prefectural
Fisheries Experimental Station, who in early December 1921 sent a specimen in a 72-litre wooden tank to Kishinouye
, who found that it was unknown and spent some time at the station to study living specimens.
Growing up to 2 m (6.6 ft) in diameter and weighing up to 200 kg (440.9 lb), Nomura's Jellyfish reside primarily in the waters between China
and Japan
, primarily centralized in the Yellow Sea
and East China Sea
. Shin-ichi Uye, Japan's leading expert on the little-studied jellyfish, artificially bred some in his Hiroshima University
lab, learning about their life cycle, growth rates and feeding habits. He traveled by ferry between China to Japan in 2009 to confirm they were riding currents to Japanese waters. A U.S. marine scientist, Jennifer Purcell of Western Washington University
, has found a correlation between global warming
and jellyfish on a much larger scale, in at least 11 locations, including the Mediterranean
and North
seas, and Chesapeake
and Narragansett
bays.
In 2009, a 10-tonne fishing trawler, the Diasan Shinsho-maru, capsized off Chiba
on Tokyo Bay
as its three-man crew tried to haul in a net containing dozens of Nomura's Jellyfish; the three were rescued by another trawler.
