The crusher claw is short and stout; the cutter claw is long and slender.
破碎机的爪子短而结实;切割机的爪子则又长又细。
In contrast, when juvenile lobsters were reared in a smooth tank without the oyster chips, the majority developed two cutter claws.
相比之下,当幼龙虾在没有牡蛎片的光滑鱼缸中饲养时,大多数都发育出了两个刀爪。
This unusual configuration of symmetrical cutter claws did not change when the lobsters were subsequently placed in a manipulatable environment or when they lost and regenerated one or both claws.
