7. Echizen Kurage
The diameter when fully grown is slightly greater than the height of an average 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 Professor Kishinouye, who found that it was unknown and spent some time at the station to study living specimens.
