Crystalback Conteratops crystallinus ("Grinding Horn of Crystals") Once erroneously called Diamondbacks, these rhino-like beasts are as their name suggests; creatures with crystal formations covering their backsides. Despite their fearsome appearance, Crystalbacks are not carnivorous animals, rather petravores (Animals that eat minerals like stone). Their bodies are covered in a stony plating alongside their crystal protrusions, with powerful mandibles used for crunching up rocks and crystals. The crystals on their backs are developed from the minerals they ingest daily, growing larger the more they eat. Depending on the minerals eaten, the crystals growing from their backs change accordingly in conjunction to it. Some examples include the crystal formations turning into red, blue, and white colors when a Crystalback consumes rubies, sapphires, and diamonds respectively. This has provided a grand number of different color variations of Crystalback gemstones. A healthy Crystalback has a shiny formation, further brightened by much crystal consumption. The crystals can actually be harvested for use in jewelry and other products, growing back as the Crystalback feeds. However, the one crystal that a Crystalback will not allow to get collected is its massive horn crystal located on its head. The largest horn crystals often denotes the leader and strongest of a group. This is a deadly weapon, which with a Crystalback's quick temper makes this seemingly peaceful petravore a dangerous creature. When angered, they charge blindly towards the threat with an earth-shaking tackle, crushing bone in the process. While found far underground and rare on the surface, Crystalbacks have been introduced to new environments as of recent events, notably the gem-loving Glunaught planet. Some have even been bred by the Glunaughts to specifically produce treats called 'Rock Candy' from their backsides. This sugary rock-like snack is a popular food item that is in high demand in Glunaught society. There are rumors that there are even variants being bred by Darkbound forces that grow Void Crystals on their backs...
