Does the hairy crab die when it cools down?

When the weather temperature is 0℃~5℃, hairy crabs are in hibernation; When the ambient temperature rises to about 22℃, crabs will end their hibernation and resume their free activities within 10 minutes. To judge whether a crab is dead, you can fiddle with its eyes. If they don't move, throw them away. Provided by Erli River Crab Breeding Base.
