Carnivorous Leech



The Carnivorous Leech is an aquatic alien creature from the science fiction computer games Half-Life and Half-Life 2.

The Carnivorous Leech is approximately eight inches in length, somewhat snake-like and white in color. The creature's head is featureless save for a round mouth bristling with sharp teeth. In Half-Life, these Leeches seem to live in fresh water, as they appear in several areas of Black Mesa which have been flooded. (In at least one case, when a room is drained, the Leeches flop harmlessly on the floor for several seconds until they die.) Although they deal relatively little damage and can be killed easily with a crowbar (for example), they can quickly overwhelm the player when appearing in large numbers.

In Half-Life 2, the Leeches appear to have adapted to salt water and are found plentifully in the ocean along Highway 17. The creatures are still fragile, but once again can quickly swarm a player with devastating effects.
