How to judge whether a crab is alive or dead:

The crab can be put into the water immediately after it is sent home, and the live crab will soon begin to blister. You can also pick up the back of the crab and gently shake it. If the claws are firm and start to tremble, it also means that the crab is still alive. On the other hand, if the crab doesn't spit, shake or tease in the water and doesn't respond, it's likely that the vertical feces is dead. /8d5494eef01f3a295258e55b8b25bc315d607c96?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85% 2Fformat%2Cf_auto
