Thorn Beasts (Earth-4001)

A thorn beast is a type of docile herd creature that is used for food and other resources by the Covenant and the Jiralhanae in particular.

History
The history of the thorn beasts is the same as their mainstream counterpart.

Biology
Thorn beasts are named for the five "thorns" that ridge their spines. A thorn beast's head and neck contain high concentrations of neurotoxins; likely a defensive adaptation against predators.
