One of the many silicon-based lifeforms that call Tivar home, these creatures exhibit herd behaviour and often stick in groups of up to 80.
These creatures have earned the nickname "Sheep" due to the thick metallic velvet that covers their plates. They shed every year and visitors have found that this velvet makes for an excellent insulator against the harsh and damp cold of Tivar. Those who wish to visit Tivar should probably buy a velvet coat since spacesuits tend to freeze up on the surface.

random details:
Like all surface organisms of Tivar, the Silicovis uses bioluminescence to see. Unable to see normal light, they have adapted to be able to process light that is specifically made by bioluminescence. By lighting up the terrain around them, they gain a sense of the area around them. They do not have eyes like we know, but instead capture reflected light in special organs that gives them a kind of "sonar". This allows them to see a short distance around them, but also spot other members of their species from far away who are emitting their own light.
It is unknown why life developed this way on Tivar, but it is thought that the planet was extremely dark in the recent past leading to this evolutionary path.
Organisms are mostly nocturnal on the planet since their light is much easier to spot during the night. Of course there are some exceptions though.

As for the body plan of the Silicovis, it has a very matte skin that absorbs heat easily, and a blueish silver fur that reflects and traps heat inside, eventually reaching its skin. It has several large metal plates on its body that act as structural support and protection for its internal organs. These plates are also where its velvet grows and also helps with temperature regulation.
The two holes in its dorsal plate are its nostrils, the 3 holes on its front shield plate are its ears, and the 3 holes on its butt plate are where it produces its sounds. (sounds similar to a flute/brass instrument)
The mouth is located just under the shield plate and is somewhat of a fluid, allowing it to absorb and diffuse nutrients into its body.
Its 3 legs are almost solid metal, with just a few muscles in between. This allows them to withstand almost any temperature but also makes them rather slow-moving.
There are a separate set of nostrils underneath its shield plate that are used when the wind is too harsh or the temperature is too cold to breathe through it normal nostrils. During these times, they often settle down in place, facing their shield to the wind, and wait for the weather to improve.

As for food, they are grazers, feeding off of the moisture catching "plants" that cover the surface in large patches.
And finally their demeanor is often gentle, but defensive in nature. They have been domesticated, but truly wild Silicovis will often batten down and emit threatening noises.
