Carnivorous Sand Clam
This clams lies on the shallow coastal margins where they hunt on semi-aquatic animals. Carnivorous Sand Clam consists of two large serrated valves approximately 2 metres across. Most of the time it spends submerged in the sticky mud. When their victim stamble near the Clam, it feels vibration of creature's movement and suddenly opens, drowing sand and victim to its shell. Though the man is too large for Clam to crash and eat, their poserful jaws could brake the leg or an arm and only destructing of the creature could help the escape.
