Sand Clam

Sand Clams are ambush "gotcha monsters" from Warhammer Fantasy and Warhammer 40K.

Warhammer 40K

Basically a living bear-trap

The Carnivorous Sand Clam is an aquatic life-form from the planet of Salutation.

This clams lies on the shallow coastal margins where they feed 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 stumble near the Clam, it feels the vibration of the creature's movement and suddenly opens, drawing sand and victim into its shell. Though humans are too large for the Clam to crush and eat, their powerful jaws could break the human's legs and only breaking the creature's shell could help the prey escape.

Warhammer Fantasy

The Sand Clam lives only in wet sand, usually by the sea shore or at the tidal margin. Although immobile, the Sand Clam is a voracious carnivore, preying mainly on seals and the larger seabirds. It lies buried under the sand and, whenever an unwary creature passes over it, the trap is sprung and the victim is caught by the jaw-like valves of its shell. Small creatures (under 2 feet) are crushed to death instantly, while larger victims are held fast and will usually be drowned by the tide. Warhammer Fantasy Roleplay
