Abstract: Eurhamphaea vexilliger (3.5cm in length of body proper) was collected from Shirahama, Wakayama Prefecture, Japan on September 19, 2012 after 72 years, and morphology and behaviour of this rare species was observed. No“ink injection”was observed except discharge of solution of iodine tincture after cut of oral lobes in which numerous“ink droplets”were found. This specimen had more comb plates (40-50) in a row than the former specimens (c.30) collected from Shirahama in 1940.
和歌山県白浜町で72年ぶりにアカダマクラゲEurhamphaea vexilligerが2012年9月19日に1個体採取され,その形態と行動を観察した. 本個体は1940年に同じ白浜町で採取された個体と全く同じ大きさ(本体長3.5 cm)だったが, 櫛板数が40-50あり, 10-20ほど多かった. "墨を吐く行動"を今回おこさなかったが, 袖状突起を強制的に取り去るとヨードチンキ色の"墨"が出て"インク壺"も確認された.
