Here are some detailed profiles of the better known species of Skinlegs. Currently, none of the specimens are tagged but I will name each one from left to right going downwards. As soon as I hit a head, I will state the creature's profile.
Sharpshooter Skinleg: of all Skinlegs, this one can fire its acid with the best accuracy. Its fangs have evolved to form a narrow funnel that forces its spit in into a stream rather than a spray. This is not only used in self defense against predators, but also to hunt food. It can fire its acid at prey hiding in tree tops as high as 7 meters. Wounded prey will eventually fall to the ground level, enabling the Sharpshooter to feed. As frightening as this may sound, this Skinleg is only 2 meters long at most, and it primarily hunts small animals like Sciuritoads and Ornitoads. The idea that Sharpshooter Skinleg, unlike most Skinlegs, used its acid primarily to hunt prey was initially met with criticism. The chemicals needed to make the acid are scarce so acid should be used in moderation. But sharpshooters live in a region of Toci1 where the plants that provide these chemicals grow in abundance. So this omnivore can use as much acid as it needs and still have ample of opportunities to replenish itself. The sharpshooter also has one of the strongest acids of all Skinlegs as it is capable of causing blindness. This allowed the species to eliminate any kind of Skinleg wishing to compete for territory.
River Skinleg: these aquatic Skinlegs are very similar in appearance to Earth’s Sea Snakes but are much less dangerous. They are herbivores and their weak fangs are only strong enough to bite through soft plants that grow in shallow waters. In contrast to the Sharpshooter, River Skinlegs have a very weak acid. It barely irritates the skin but it does smell very bad. When a River Skinleg feels threatened, it will spit a cloud of chemicals. Like the ink of a squid, the cloud obscures the enemy’s eyesight, enabling the Skinleg with a means to escape.
Black Skinleg: the infamous Black Skinleg is the most dangerous Skinleg on Toci1. While it only grows on average up to 2.5 meters long, its acid is the most powerful of all Skinlegs. By combining different chemicals stored in various glands in its lower jaws, this carnivore can create an acid so strong it can melt away limbs, leaving only a stump. One unfortunate predator even had its entire heads melted right off the neck and of course died instantly. To make matters worse, Black Skinlegs are short tempered, and the slightest intrusion in its personal space will cause it to attack. Black Skinlegs are very territorial towards one another but they will not use their acid on a member of its own species. Like Rattlesnakes on Earth, they will instead wrestle until one member has its head pinned to the ground.

Periscope Skinleg: this is a bulky Skinleg whose body almost instantly shrinks to a short spade-like tail. It buries itself in the mud near rivers waiting for prey to come to its lair. Once its sense movement close by thanks to sensitive pores in its skin, it will emerge from the soil and grab the passerby with its mouth. Periscope Skinlegs have a fairly weak acid spit but their fangs are very strong, enough to break small bones. When danger approaches, they will attempt to hide themselves by retreating in their lairs. If anything tries to dig them out, they will be greeted with an acid geyser. During mating seasons, Periscopes from all over gather to important water sources to compete for mates. Males will demonstrate their strength by attempting to stand upright on their muscular tails.
Spotted Skinleg: these herbivorous Skinlegs only grow about a meter long on average and are highly vulnerable to predators. Their acid spit can soften the tough vegetation they feed on but do little to discourage predators. Their best defense is camouflage, by hiding in foliage or inside splintered/hollowed-out trees with color similar to the pattern on their skin. The one above is shown being eaten by a Periscope Skinleg.
Big-Eyed Skinleg: the large eyes of these predators enable them to see better in the dark. Their habitat consists of large rock formations found near waterfalls throughout Toci1. They can cling to the face of these monuments waiting for prey to come within sight. It then slowly approaches its target until can get close enough to lunge forward and catch it in its fangs.
Dung Skinleg: these 50 centimeter long skinlegs have evolved to live alongside the Cacanians in the Augean Dung Fields. If it weren’t for the Dung Skinlegs, the field would actually cover a much greater surface area. These animals are coprophagians, meaning they feed on the dung itself. They feed from the surface going downwards until they reach dry ground below. Their activity allows sunlight to reach down to sprouts below that have more difficulty growing through the layer of fecal matter.
Emperor Skinleg: the third longest Skinleg is also one of the most recognisable. It is actually the largest member of a group of Skinlegs who all share a similar body structure: a skin larger arranged like the cowl of a cobra’s. Similar to its Earth dwelling lookalike, the cowl is designed to intimidate potential threats to the Emperor Skinleg’s wellbeing. It will only spit its acid if danger persists. Several animals, such as the herbivorous Snake Mask (tapejara.deviantart.com/art/To…) have taken advantage of the Emperor Skinleg’s threatening posture to scare off their own predators. Emperor Skinlegs are omnivorous and will feed on a variety of things including Ornitoads, Sciuritoads, Blugs, Flowers, Lichens, Eggs and even other Skinlegs.
Raft Skinleg: these meter long predators have some of the longest skin extensions relative to body size of all Skinlegs. This design allows them to float on the surface of slow current rivers, allowing them to hunt small Fleels and aquatic Blugs. They themselves are preyed upon by large Fleels can coat the water surface with putrid chemicals should they feel threatened.
Vine Skinleg: arboreal skinlegs that hang upside down from branches to catch prey and survey their territories. They are able to maintain that poses that to the Velcro-like skin found on the underside of their tail.
Mini Skinleg: as the smallest Skinleg currently, Minis do not grow much longer than the average human thumbnail (the own shown above is not to scale). They are usually found in giant colonies at the bottom of holes scattered across the rainforest. Anything that ventures into its lair is instantly attacked and repeatedly bitten by the irritating fangs of the swarm. If anything too dangerous comes to visit, the swarm of Minis will secrete a little bit of acid that causes severe burn if exposed for too long. Curious herbivores have had their muzzles covered with permanent scars due to their reckless decisions.
Horror Skinleg: one of the best known animals known to live in the area known as the haunted forest, Horror Skinlegs are truly a product of nightmares. Their red fangs are able to stretch out widely as they are loosely connected to the head. This allows them to swallow prey bigger than themselves. Bear in mind that these are the second largest Skinlegs known, growing as long as a hearse. Its mouth is constantly leaking a small amount of acid. This is used to disable prey caught in its maw before the imminent thrashing causes damage to the Horror Skinleg’s body. Females will occasionally retain prey in their mouths and spit out the predigested remains to feed a nest full of these abominations. The pearl coloring of their heads is also the same color as a skeleton, providing some camouflage to the monsters that would feed on it.
Devil Skinleg: living in drier forests away from significant water sources, Devil Skinlegs are a rare find on Toci1. What makes them unique among all life forms on the planet is that they will actually become more active during the deadly solar flares. They skin oozes a thick ointment that acts as a powerful sunscreen that protects them from ultra violet light. As most animals tend to concentrate in specific areas during flares, it allows the “horns” on the animal’s head to pick up the scent of all its prey hurdled together. Thanks to its higher-than-average speed for a Skinleg, the Devil quickly hunts them down and attacks with its fangs. Should it itself be targeted by a predator, the Devil Skinleg will spit a peculiar acid that also has a high temperature. There’s a small chance that if that acid comes in contact with dry tinder, it can spark forest fires.
X Skinleg: this skinleg gets its name from the way its skin extensions are arranged with the spikes running along its back. Together they take the shape of the letter X. It feeds primarily on blugs but will occasionally feed on small purple berries that are responsible for its skin color. They are commonly found in the same areas as X Skinleg but will rarely acknowledge each other’s existence.
Quill Skinleg: along the length of its body, small patches of skin have coiled and stiffened, turning into the quills from which it gets its name. Quill Skinlegs grow about a meter long and feed primarily on blugs that it chases after in low lying foliage. The quills are used for defense against large animals that step on it as the pain they inflict will cause the beasts to back off before they can crush the Skinleg.
Foam Skinleg: as this insectivorous Skinleg matures, the cavities in its skin fill with methane harnessed from the swamps that it lives in. This not only lightens its body to make moving about easier, but also causes its body to look like a cluster of bubbles. Foam Skinlegs use this to hide in shallow water and wait for blugs to come within reach of its fangs. Foam Skinlegs are ambush predators but can use great bursts of speed to evade their own predators. Though this is only for short bursts and they must rest frequently or resort to spitting acid.
Ribbon Skinleg: considered to be the most beautiful Skinleg, Ribbons live within the trees found in tropical climates. The coloring is used by males to attract females who aren’t as flamboyant. The ribbon shape of their bodies likely enables them to hide in shallow crevices, the only shelter available in the treetops. The skin pattern is the same for each Skinleg but the brightness of each color can be improved by eating specific fruits. To ensure a regular supply of nutrients needed to keep their skin beautiful, Ribbon Skinlegs will viciously defend their fruit tree. Any herbivore that tries to consume too much fruit may receive an unpleasant surprise in the form of acidic goo. The acid of the Ribbon Skinleg is stickier than the average Skinleg, making it harder for the animal to clean off and in turn, causing greater scarring or even death.
North Leaf Skinleg: this Skinleg lives at higher latitude than any other species. Skinlegs are cold blooded so normally they need regular exposure to heat sources to remain active. North Leaves live entirely on top of the giant leaved plants that dominate the poles of Toci1 and remain constantly bathed in the light of Toci1’s two suns. The color of their bodies provides camouflage from predators. In the event of a solar flare, the North Leaf curls into a cylinder and rolls down between the branches. The bloating leaves should then close up on it, protecting it from the flare. An unlucky North Leaf who rolls off the tree altogether will have to make a long sluggish journey back to the emergent layer.
Giant Skinleg: as the name suggests, this is the largest Skinleg currently known, growing up to 6 meters in length. Giant Skinlegs are primarily scavengers and can consume entire corpses of megafauna within a weak. They are usually placid and will even let Ornitoads perch on its body so they can pluck any parasite off its skin. But if dead animals become scarce, it will slowly make its way towards slow moving animals and attack with its massive fangs. Its victims are oftentimes females trying to defend a nest of youngsters. The targeted parents will likely try in vain to strike the Giant Skin legs with hooves, teeth or spikes. But the predator has very thick thin and most animals can do little to fight off a slow death. In the event that a Giant Skinleg has stumbled upon an animal it cannot fight off and becomes at risk itself. It will release an acidic spray from its mouth. The Giant Skinleg’s acid is more gaseous than liquid however and typically is found inhaled by its target. This will cause respiratory difficulties for the target but is rarely lethal.
Tiger Skinleg: these 3 meter long creatures are easy to photograph as they easily stand out of the green vegetation due to their coloring. They are also found in large gatherings whether it is mating season or not. As of 2016, they have never been observed doing any kind of movement. However, a probe that has likely gotten too close for comfort has caused the Tiger Skinlegs to unleash a very foul odor. The latter was quickly sensed by hundreds of other species hiding within the vicinity and they all scattered away for the stench.
Angel Skinleg: a distant relative of the Giant Skinleg, Angels belong to a family of unique Skinlegs that have flat rather than elongated bodies. The purpose of such a body is not fully understood, but it may allow the Angel Skinleg to slide into crevices found in rock formations.
Mud Skinleg: the better studied relative of the Angel Skinleg has demonstrated how it makes use of its body shape. The wide surface area keeps it from sinking into the muddy terrain that it stalks while hunting prey that consists mainly of blugs. Mud Skinlegs have also been shown luring predators towards mudbanks waiting for them to get trapped. Once the predator has died from starvation or dehydration, hundreds of Mud Skinleg will be lured to the smell of decay and begin feeding on the carcass. Mud Skinlegs have never been seen using their acid as of yet, but it is known from autopsies that they do possess glands.
Common Skinleg: found across 80% of the planet, Common Skinlegs have been found to share the same environments as all the other Skinlegs listed except for the North Leaves. They grow just under a meter in length and are preyed upon various larger predators such as Stiltfoot Snake Eaters and other Skinlegs. They do spit venom and have relatively large glands so they can store a lot of chemicals for their size. However their accuracy is very poor and is more likely to deceive predators from attempting to eat it rather than cause any true harm. However Common Skinlegs are very prolific and females lay more eggs than any other Skinleg known, up to 50. Common Skinlegs are absent parents and may even cannibalise their young.
Two-Headed Skinleg: this is not an anomaly. Two-Headed Skinlegs are a common sight and almost every individual encountered had two heads. They were the second animal encountered after the Gemini where polycephaly was the norm for the species. The advantage of having two heads makes the Skinleg look more threatening for animals trying to evade a spray of acid. The truth is, each head contains a separate enzyme which the heads spray simultaneously onto the same targeted area. The chemicals then reacts outside the Skinlegs body every time, preventing any kind of fang damage that some Skinlegs unfortunately suffer from after defending themselves. Two-Headed Skinlegs are omnivorous but only eat one type of plant. The plant is similar to catnip on Earth and causes the heads to feel more relaxed, eliminating the urge to attack each other.
