Diving right at the foot of the coastal rock embankment in Giang Hai commune (Phu Loc), precisely at the moment when the waves had not yet reached, Mr. Hung extended his hands into every crevice. In just a moment, he firmly held in his hand a stone crab (Gecarcoidea) with its two large claws.

A neat preparation with a flashlight, a shovel, a one-meter-long stick and a bag is just enough for an interesting chase of ghost crabs at night.
