CavernClan cats are typically large, stocky cats with short muzzles, ears, tails, and large paws and noses. They have thick, dense fur that comes in a variety of colors. CavernClanners may have a variety of features, such as mandibles, extra legs, eyes, horns, honeypot tails, stingers, elytra and wing-like ears in correlation arthropods. CavernClanners have antennae: two on their heads, and a range from six to ten on their backs. These antennae do not grow back when plucked, but return if damaged in adolescence. These antennae act as extra whiskers, detecting changes in the wind and vibrations. They can also pick up on scents and tastes! Gemstones sprout from their bodies and replace their claws into unsheathable talons for fighting and digging. These gemstones are around a 7-8 on the mohs scale of hardness. All CavernClanners have some degree of bioluminescence from their crystals and antennae (and mouths and teeth, if they take after these crystals), which flares and dims with emotions or at will. Their glow gradually fades when they die. The shape of their gemstones is in its raw form unless worn down. A guide to raw crystal shapes can be found here.

CavernClanners can be based off of most animals under the phylum arthropods, excluding most crustaceans. This includes,

• Arachnids (spiders, scorpions, etc., horseshoe crabs excluded)

• Insects (diving beetles, mantids, termites, moths, etc.)

• Myriapoda (millipedes, etc.)

• Terrestrial isopods

While CavernClanners may seem burly and slow, they are actually quite quick in their digging capabilities! These cats are able to tunnel down into the rocky earth at a rate of 20 feet per hour! When in shallow, easy to dig soil or clay, they can dig even faster. CavernClanners are also incredibly flexible, and much like the bugs they are based on, can flatten to nearly half of a normal cats size to squeeze down into tight gaps and narrow passageways without risk to their bones. CavernClanners have little issue with low oxygen and polluted caves, and are capable of surviving days in conditions that'd asphyxiate others. They can withstand depths of up to 9,842 feet in their caverns!

CavernClanners all possess geokinesis- the ability to move, control, and manipulate any and all types of earth! Mud, clay, crystals, dirt, and stone- you name it, these cats can control it! These abilities are most commonly used to fortify or collapse tunnels, or in battles with large opponents. Some CavernClanners have honed their abilities enough to create art with their geokinetic abilities, but most don't bother.

CavernClan leaders have much more gemstones than their Guardians. The crystals form large, segmented patches of impenetrable armor around the leader's body, primarily around their backs. They are also just physically stronger than the Guardians, and have stronger geokinetic abilities. CavernClan leaders also produce a toxin in their spit- it's not only sticky and hard to wash out, but it stings their opponent and has mild paralyzing effects, making those they bite sluggish and slow! Leader marks are either on the cheek or within a crest of gemstones upon their forehead! They also might have larger mandibles or horns!
