Headcrabs, they've been described as cream puffs, target practice and, "That damn thing that gives you a heart attack whenever you see a shadow." But what, exactely, are they? The easiest answer is that they are a parasite, and that while perhaps capable of sexual reproduction are more than likely asexual reprocuders. But... what do we really know beyond the horrors of zombification and advanced physical mutation these creatures are capable of inflicting upon hapless humans?
Behavior and Food Chain Position
Upon their (possible) homeworld of Xen, these creature are, probably at best, a minor pest. Bullsquids, xenomorphic ant lions, and even Vortigaunts seem to treat these creatures with not only outright hostility, but also also impunity. Which leads me to suspect that they are more than likely at the bottom of the Xen ecological food chain. From the brief glimpses of Xen given in HL1, a lot of Xen's plants (or aproximate life form) sport a number of growths similar to the human head in size and/or shape. Headcrabs have no noticable eyes, or the very least they have no noticably large, complex, and dedicated visual organs like eyeballs on thier bodies and could easily mistake a head for its natural food supply.
Soon to come... Infiltration.
