[[Image:HalfLife Barnacle.jpg|thumb|300px|A barnacle, as seen in ''[[Half-Life]]'' ('''left''') and ''[[Half-Life 2]]'' ('''right''').]]

(contracted; show full) for ''Half-Life'''s barnacles (as a sidenote, the scientist's use of the term "gestation" may be incorrect depending upon how barnacles reproduce and disperse).  However, it is known that they are attached very firmly and permanently, as evidenced by their continued attachment after death. In the Half-Life 2 series, the Barnacle has a "second mouth" that it uses to eat and when killed, the mouth hangs out from its actual body that can be seen at all times.
 This mouth is usually a lot more pink than the barnacle's original skin color.

== Behavior ==
Barnacles are relatively simple creatures. They do not appear to possess any [[sensory organs]] (beyond the tongue's sensitivity to touch) and only a small degree of [[intelligence]](if you feed them a random item from the ground, they will attempt to eat it once, but recognize it the next time, and ignore it.) - instead of actively hunting prey, they feed by reacting to external [[stimulus (physiology)|stimulus]], in the form of animals which come into contact with the barnacles'(contracted; show full)
