Thorn beast

Thorn Beasts are used as food by the Covenant, and Jiralhanae in particular. They are docile herd. Their neck and head contain a high concentration of neurotoxins. It is unknown what causes this or what function it has for the animal, but it is possible this is to keep predators from eating it. .
