The Worbals and extremely bioelectric. There is no definite amount of energy a Worbal can produce that we know of. Ancient Worbals used this ability to hunt, and while this is still viable today, modern Worbals use it for powering devices and basic communications, such as a greeting.
Worbals have two nervous systems. One functions similarly to animals on Earth and the second is used for their bio-electricity.
Worbals are covered in conductive hairs. These hairs are slightly thicker than their regular fur, but visually indistinguishable at a glance. They are concentrated around the ends of their limbs, tail, ears, and along their backs near the quills. These hairs connect to their second nervous system.
Worbal colors range naturally in the warmer range from yellow to red. Natural blue coloration is a recessive trait. Markings can vary greatly from stripes to spots and everything in-between, likely as a side effect from the gene-therapy color changes they have been using for decades. These markings are typically a lighter or darker shade of a Worbal's base color, but can sometimes be white or black. The non-bioluminescent section of a Worbal's quill will always be black. Albinism can occur in Wobals, and in such cases, the black portions of quills turn white as well as their fur. Bioluminescence continues to range all possible colors.
Worbals have used gene-therapy to change the color of their fur. It's about as expensive as dying hair on Earth. It is permanent, but reversible at the cost of re-changing their color back to original if the Worbal so desires. Changing their markings is more expensive than a color change, but still possible. Despite this technology, their bioluminescent hue cannot be changed. A Worbal's offspring will continue to be born with natural colors regardless of their parents' color changes.
Visually, it’s difficult to differentiate between male and female Worbals. Physically, they’re built the same and can have no problem competing in the same sports. On average, female Worbals naturally have lighter fur, but with color changes common in their society, this is more often false than it is true. Other than genitalia, there aren't any major differences between the two.
Worbal bioluminescence ranges through all the visible colors. There are superstitions about the meaning of these colors in Worbal culture, but none have scientific foundations or evidence to support them. It's theorized that they used to all be the same color, but since the ancient times on Cansevai, random mutations have introduced a wide range to the spectrum of possibility.
Worbals cannot control the color, but do have complete control over the brightness. There is no defined language using the pattern of quills off and on, mostly because a Worbal can’t count on having all of their quills all of the time as well as the total number of quills differing per Worbal. However, small groups such as duel teams or packmates have made use of this to communicate small packets of information wordlessly.
Worbals are cave creatures with very poor eyesight and below average directional hearing. Instead, they mostly see using a method similar to a shark's electroreception, but with their own twist. By producing their own electromagnetic field, they can feel the area around them. The range of this field is estimated to be 4-7 meters at rest, but without the knowledge of the extent of their bio-electricity, the true limit to this size is unknown when they actively expand it.
Worbals have poor farsight and are sensitive to high amounts of light. Their eyes are secondary to their Electroreception.
Worbals shed all their quills about once every year and grow them all back within two weeks. A shed Worbal quill can be used as a pen with luminescent ink. The quills are similar in shape and color to a grass-like plant, the Arvadi Plant, that lined the caves of Cansevai. These quills camouflaged the Worbals as they hid on the cave walls to create a tesla gate for killing their prey. Worbals can lose their quills through disease or simply something pulling them out. In which, they will grow back within 3 days and continue to be shed on schedule with the rest of the quills. Worbals can often lose a few quills in their sleep.
