形态特征 Morphological Characteristics

体长70余厘米，宽约30厘米，全体深褐色，头胸及腹部各有1坚硬的甲壳被覆。头胸部背甲广阔如马蹄形，背面有3条纵脊，中央1条的前端有单眼1对，两侧纵脊上，各有复眼1对。腹面有口，口缘有附肢6对，除第1对螯肢由3节组成外，其他各肢均有6节；第2对为脚须，幼体及雌体均呈钳状，雄者则末端呈1弯钩。另4对为步足，位于口的两侧，基节上均有倒刺，前3对的末节均呈钳状。腹部背甲呈六角形，两侧有缺刻及短刺，腹面有板状的附肢6对，附肢为双肢型，内肢细长，外肢宽阔；第1对附肢左右愈合呈盖板，下有生殖孔1对；其他5对的外肢后面各有1对叶状鳃。腹部下面有1条强直的剑状物，称为剑尾。穴居，生活于海底沙土中，以海中的蠕虫及软体动物为食。
The body is over 70 cm long and about 30 cm wide, dark brown in color, with hard carapaces covering the cephalothorax and abdomen. The dorsal carapace of the cephalothorax is broad and horseshoe-shaped, with three longitudinal ridges on the back; a pair of simple eyes at the front of the central ridge, and a pair of compound eyes on each lateral ridge. The ventral side has a mouth surrounded by six pairs of appendages; except for the first pair of chelae (composed of three segments), all other appendages have six segments. The second pair are pedipalps—pincer-shaped in juveniles and females, while males have a curved hook at the tip. The remaining four pairs are walking legs, located on both sides of the mouth, with spines on the basal segments; the terminal segments of the first three pairs are pincer-shaped. The abdominal carapace is hexagonal with notches and short spines on both sides. The ventral side bears six pairs of plate-like biramous appendages—inner branches slender, outer branches broad. The first pair fuses into a genital operculum, with a pair of genital pores underneath. Each of the following five pairs has a pair of leaf-like gills on the posterior side of the outer branch. A rigid sword-like structure extends from the underside of the abdomen, called the tail spine (telson). It is burrowing and lives in sandy seabeds, feeding on marine worms and mollusks.
