Athanas
Athanas is a genus of small, brightly colored, and active shrimps belonging to the family Alpheidae, commonly known as “snapping shrimps” or “pistol shrimps”. They are characterized by their unique asymmetrical claws, with one much larger than the other. This larger claw, known as the “snapping claw,” produces a loud snapping sound when it is closed rapidly, which the shrimp uses for defense, hunting, and communication.
