The planet Shand and its inhabitants are also known as Shand (pl. Shandi). They are about three metres high and look like a cross between a bear and a walrus. Tusks are a status symbol for adult Shand, those who are specialists in linguistics and diplomacy may have theirs replaced with detachable versions.
Shandi can only survive for about two days without food before reverting into ravenous beasts, killing and eating until their hunger is satisfied..
It should also be noted that the primary food source of a Shand is other Shand (Only Shand proteins satisfy the hunger). Though the practice has much reduced since the introduction of replicated food, on the home world honourable cannibalism still takes place in "The Game".
How Shands originally gained their necessary proteins is unknown and is the sort of situation that would require Narrative Causality to explain.
