Horranth
Horranths are an existing species from Legends.[1]
By 5 ABY, the Horranths on Tython had evolved to the point where they would band together in ferocious packs and creating a collective mind that was much sharper than their barely-sentient individual minds. K'uaz and T'iaz enjoyed hunting them and recommended the practice to Palpatine after one of their hunts.[2]
