Stalker Teeth

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

A good method to obtain Stalker Teeth is to tease them with the Seamoth. The Stalker will bite the submersible, and leave behind a single tooth. You can also temporarily tame the creature by feeding it Peepers. The player can get a stalker to drop a tooth by dropping Metal Salvage near the creature, however, this method is not recommended, as the player is likely to get attacked.

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

Data Bank Entry (Stalker Behavior and Physiology)
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?
