The ‘original’ Nihorra, Cave Nihorrae do not have eyes. The upper portion of their skull bulges forward into a huge lumpy brow ridge, usually asymmetrical, and then sags down jaggedly into the muzzle, which is short and broad. Their tusks are short, thick and stubby, and their jaws are crooked and do not meet properly. They have two sets of ears, one on top of the head and one, more like overgrown fleshy whiskers, just behind where jaw meets skull.
The ‘speaker’ part of the entire species’ obligatory fancy folklore name is from the sound they make to echolocate. A Cave Nihorra does not have vocal cords for roaring. Instead, it sucks in massive gasps of air and howls using its malformed jaws and big baggy throat. It sounds like if
you take a vaccuum cleaner tube and spin it in the air around your head, except much louder and carefully calculated for accurate echolocation. The upper frequencies are felt rather than heard, and while harmless to a human or another Nihorra, they can induce ear canal damage and bleeding to creatures with sensitive hearing. Aquifer caves with guano residue and no bats can indicate a Nihorra cave.
This creature only howls while wandering its cave or crag of choice. Once it has a fix on its prey, it goes completely silent. Its hunting crawl is more of a slither, legs spreading to the sides like those of a lizard, letting its body flow so close to the ground that it can feel every minute vibration.
Cave Nihorrae are white-furred when born, their hair translucent like that of a polar bear, but soon turn a gross greenish black due to a type of light blue-green cave algae that quickly forms a benificial relationship with a very black lichen and grows all over the fur.
The claws of a Cave Nihorra are like the bastard children of mole claws and velociraptor sickles, splayed out grotesquely in all directions. Because they do not have the hooking tusks of their less subterranean cousins, they rely heavily on these limbs for offense.
