Dagannoth hide

Dagannoth hides are a member's only item used in the making of Fremennik armour. They are used, along with coins and either rockshell, other hides or bones to make rockshell, spined or skeletal armour respectively. Helmets require at least one hide, leggings require two hides, and tops require three hides. Dagannoth hides can be obtain in several ways:
 * As drops from most Dagannoths (except the Lighthouse dagannoths).
 * By trading with other players, either directly or by using the Grand Exchange.
 * By looting certain impling jars in Impetuous Impulses. A Ninja impling jar can contain three noted dagannoth hides and a Spirit impling jar can contain one.
 * By gambling in Soul Wars.
 * By successfully defending/prosecuting in the Barbarian vs. Wizard Court Cases.

A dagannoth hide is also the tertiary ingredient in infusing Spirit dagannoth pouches.

Trivia
If you look closely at the icon of the hide, you will notice some dark shadows, these seem to be a Dagannoth's spikes on its back, which means, that most hides dropped from Dagannoth's are from its back.
