Will crabs crawl into cages when it's cold?

Crabs won't climb into cages in this weather.

Crab is an aquatic animal, which usually lives in rivers, lakes and oceans. In cold weather, crabs will look for warm water or hibernate in caves.

The ground cage is a tool for catching crabs. It is usually put in water to trap crabs through meshes. However, the crab won't climb into the cage on its own initiative, because it doesn't know what the cage is or what's inside. So even if the weather is cold, crabs will not climb into the cage on their own initiative.
