Stalker Teeth

The Stalker Tooth is a raw material dropped by Stalkers under special conditions.

When the Stalker sees metal salvage, it will approach the object and try to pick it up. When this happens, the creature will sometimes leave behind a single tooth.

Another method is to tame stalkers by feeding them Peepers.

It is not possible to obtain Stalker Teeth by killing stalkers.

Extended analysis of Stalker dental samples has been completed.

In other local lifeforms tooth composition follows a familiar biological process whereby a calcified structure is grown in the gum.

Stalker teeth are unique in exhibiting extraordinary lightness and strength, and containing only trace amounts of calcium. They gain their structural integrity from a titanium/iron compound somehow produced in the Stalker's body.

This suggests some possible explanations for the creature's metal-gathering behavior, but raises more questions: Assessment: More research required.
 * By what process can the stalker convert raw metals into dental structure?
 * What explains this seemingly costly evolutionary adaptation? An armored opponent? A calcium shortage?
