These are the classic, slow-moving headcrabs. They attack by jumping at the player's head and inflict a nominal amount of damage. Almost any weapon can dispatch them easily.
{{toc-right}}
Commonly found attached to a [[Npc_zombie|zombie]] host body, they will detach if that host is sufficiently damaged below the head.

There are several other [[headcrab]] variants and associated zombie types.

See also [[env_headcrabcanister]] which is a mortar shell containing a payload of headcrabs. The mortar shell inflicts damage within a radius of where it lands and releases headcrabs after impact. Triggers and entity options offer control over impact damage and when the headcrabs are released, among other options. 
{{PlacementTip|Classic headcrabs can be paired with their [[npc_headcrab_fast|fast-moving]] or [[npc_headcrab_black|poisonous]] relatives to make it more interesting.}}
{{PlacementTip|Avoid the cliche of placing headcrabs in vents; they would likely be more of an annoyance than an improvement on gameplay.}}
{{bug|If a headcrab is burrowed, using inputs or command that would kill it like {{code|sethealth 0}} or {{code|npc_kill npc_headcrab}} does not work. They get ignored and the headcrab's [[health]] doesn't change.|tested=Half-Life 2}}
