A marine animal belonging to the order Decapoda, class Crustacea, family Paralimniidae. An important species in the fishing industry, it is crab-shaped but, like the red king crab, is classified as an Anomura (hermit crab). It is distributed in the northern Sea of Japan, from Hokkaido to the Bering Sea, but its Japanese name comes from the fact that it was once abundant in the Hanasaki Peninsula (Nemuro Peninsula). It lives in shallow waters, and small individuals can be seen among seaweed on the shore. Its carapace is about 15 cm wide and long, with many projections, and the spaces between them are smooth. It resembles the red king crab, but can be distinguished by its short central spine on its rostrum with a rounded tip, and its thick, short walking legs. It is dark reddish-purple brown when raw, and turns bright red when boiled. With the stricter fishing regulations for red king crab, the resource value of this species has been reevaluated.

節足動物門甲殻綱十脚(じっきゃく)目タラバガニ科に属する海産動物。水産業上の重要種で、カニ型であるが分類学的にはタラバガニと同様に異尾類(ヤドカリ類)に属する。日本海北部、北海道からベーリング海にかけて分布するが、かつて花咲半島(はなさきはんとう)(根室半島)に多産したのが和名の由来である。浅海にすみ、小形個体は磯(いそ)の海藻の間でもみられる。甲幅、甲長とも15センチメートルほどで、多数の突起があり、それらの間は滑らかである。タラバガニに似ているが、額角(がっかく)の中央棘(きょく)が短くて先端が丸いこと、歩脚が太くて短いことで区別される。生時は暗赤紫褐色で、ゆでると鮮やかな赤色になる。タラバガニの強い漁業規制とともに、本種の資源的価値が見直されるようになった。 [武田正倫] 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
