One foot is bigger and the other is smaller! Qingdao Jiaozhou Bay estuary beach flooding with crabs

On August 31, 2018, the tidal crabs were active in the mudflats of the estuary of Jiaozhou Bay in Qingdao. On the beach where the Baisha River and the Ink River meet, a large number of tidal crabs grow densely, waving a large sting in demonstration, and another small stinger eating sand debris. The tide crab has a pair of matchstick-like protruding eyes, and when foraging, both eyes stand high, observing the surrounding movements. As soon as the situation is spotted, it quickly burrows into the hole.

A large number of small sand crabs spread across the mudflats.

Citizens catch crabs.

The biggest feature of the tide crab is a pair of claws of great size, and the large claws on the front chest resemble the shield of a samurai. The tide crab will make the action of dancing large claws, so it is called the tide crab. The purpose of this "tide-stirring" action is to intimidate the enemy with a large claw, or to court.
