Below is a list of Animal-Life found on Icarus. To make it easier on everyone the list is divided into a few categories: Animals (mammals), Birds (winged creatures), Reptile (reptillian creatures), Fish (water-based creatures) and Bug (bugs & dangerous creatures).

Anteloct
[AN-tee-lokt]
This is an eight-legged deer-like creature which They are around 6' at shoulder height and are more than ten feet long. Both males and females have two horns that grow throughout their lifes. they do not shed them, but they can be broken. They are considered prey animal, herbivorous, and can be eaten by nearly anything large enough (or with enough members in its pack) to hunt it, like humans. The Antiloct is hunted for it's spicey meat, it's hide and it's horns which can all be used for a variety of objects.
At the start of spring (or around a rainy season depending on where they live), is usually the time for Antilocts to give birth to their young. Usually a female bares 1 or 2 calves, a 3rd or even 4th is possible, but would certainly be picked off by a predator and not missed.
Eyes set to the sides of its long face, with a longish tongue for browsing or tearing off leaves, grass or fruits. 
The Antiloct inhabits different climates and zones but with different types of coloration and adaptations, rather like Earthly deer. 
On the plains, this animal is slightly taller on the front end with a sloping back end. Its eight legs are quite spindly and designed to quickly sprint rather than kick. It's neck is longer than a deer's but not as lengthy as a giraffe. It has tan and brown mottled fur, ending in pale fetlocks and most often a white or pale yellow rump. Females and males both have short horns.
In dense shrubs and scrub desert, it would be shorter, with paler fur which is much shorter but dense with an undercoat for insulation. Males have longer horns, while the female's would be stubby.
In light forest or temperate rain forest, they would be long, and many suited for half-water conditions, with longer more matted fur in dark colors ranging from greens to blacks. Females would not have horns, but might have velvety stubs like a giraffe's.
In rainforest or wetlands, they would be much squatter, perhaps down to only 4' at the shoulder. Their coats might go through blues and greens, with black mottling. These would spend a lot more time in rivers, ponds or wet lands than the other types, and would have slicker fur. Males and females would both have short, sharp horns.
In heavy forest they would greatly resemble eight legged moose, with tall, heavy horns on the males and lighter but still long ones on the females. Coloration would range between tan and russet, with fawns being spotted at birth.
In high-forest or arctic conditions with snow, their legs would be long, but body compact. These would have stronger hind legs than the others, perhaps to fend off the tiger-like creatures which hunt it. Both genders have medium sized horns.

Bicorn
[BYE-Corn]
Horse-like creature with two back-swept horns rising from just above the eye ridges. The Bicorn is semi-intelligent and able to be tamed and used for travel. Their legs are long and spindly, therefore more fragile then Earthen horses, but allow them to move at nearly twice the speed. Wild Bicorns have long manes and tails while those in captivity have their hair cut short for practical use. Not only does this distinguish them from the wild herds but it also prevents the rider being whip-lashed by the long manes. Their hooves are split to give them easier movement over rocky regions (their natural homelands being plains and valeys). Their coats can come in almost any earthen colour and range all the way up to white, silver and gold.

Camels
[camels]
 Your standard earthern camels, one of the few species that was salvaged from the 'Hyantis' after the crash. Camels now are the most used way of transportation through the desert (aside from draks of course).

Nurk
[nurk]
Nurks are pack mammals that look like goats. They are bigger though, about the size of a deer with a long shaggy fur and two long arched horns. Nurks can be found in the wild almost all over Icarus, except in the deserts where they cannot find the necessary amount of grass to feed them.
When kept, their long fur is sheered twice a year (at the beginning of spring and halfway through summer). Though they are quite strong, with heavy legs and a calm temper, they are not made to pull carts. When bound to ride or pull, they go completely rigid and refuse to move, no matter how much sweettalk is applied.

Pruts
[pruts]
 Pruts' are small, furry rodents with two sets of ears, standing high on their head. Each large round ear can be moved seperate from the three others giving it an almost perfect suround sound hearing. Prutses walk on four legs, which end in paws that resemble a hand with four fingers and a thumb. This makes them agile climbers, which is of great use to them in their forest habitats. Prutses also have a set of bat-like wings on their back that they cannot fly use for flight, but in stead use to camouflage themselves against the trunk of trees. Lastly they have a long agile tail that can support their body weigth if necessary.
A pruts female can have a litter of 4 to 10 pups twice a year. About half of those fall victim to larger animals that hunt them before they reach adulthood at 4 months of age. A common Pruts can become 4-6 years in age before it dies.

Vulpa
[VUHL - puh]
 Vulpas are a small, fox-like mammal about 1 foot 8 inches in height on average but can reach 2 feet. They have large ears and a large fluffy tail. Male Vulpas have tufts of fur of the tip of their ears while female Vulpas have none.
The color of a Vulpa can range from plain, to spotted, to striped and can be basically any color. The Vulpas are a generally vicious species, as they have to survive out in the wild. Their teeth are razor-sharp and they have fairly good reflexes. They were bred from earth caracals (one of the c-viles that survived the crash).
Once tamed, a Vulpa can be a very loving creature and they rarely turn on people. If one feels they or their partner(s) is(are) in danger, then they will attack the offender. A Vulpa has a litter of up to 5 pups every two years or so and they can live for 15-20 years.

 

Chikens
[CHICK-uhn]
One of the few species salvaged from the 'Hyantis' after the crash. Chickens still run around in farms, providing eggs for the humans to eat.

Drak
[drahk]
 Draks, the dominant species on Icarus, are large winged reptiles. They have four limbs and two sets of wings that allow them to fly fast, but also to hover when they need it. They are very intelligent, learning languages fast and docile. They proved to be just what the humans needed in their fight against the Nex Necium. The draks, coming in 12 colours, spit acid that burns through even the thoughest Nex hide and their ability to pair with a human to form an even closer bond has ensured that the devastation of Nex Necium attacks has gone down dramatically.
Draks grow to adulthood in about 4 years. They can form a lifelong bond with another drak of either gender, to mate for life, or in the case of same-gender pairing, to form an unseperable unit. 
A female Drak in heat, chooses which male she wants to fly her. Shortly after she has been impregnated she retreats to the Deep Caverns where she waits for her eggs to hatch. During the hatching, no humans are allowed inside the deep caverns, and even the females mate is sometimes shunned from this event. After the hatching, the mother names her draklings before she allows them to go out to pair a human. 

Fairy Drak
[FAY - ree drahk]
 Small creatures of about 5 inches in length, but some vary in length of anywhere from 3-10 inches. They can have either four legs or only two legs depending on the area they are from. They come in the same colors as their larger cousins, but rares can be found more commonly among these smaller creatures as they breed sooner than their larger cousins do.
Fairy Draks grow to adulthood within 6 months of hatching and have a life span of about 10 years. Depending on how well they are taken care of, they may live a few years longer or shorter.

Teryx
[Tey-rix]
 An eight limbed bird that somewhat resembles the earliest form of terran feathered birds. Teryxes are very colourful with two front legs, two arms, the hind talons, and small claws on the wings. They can attach themselves to walls like bats because of their wingclaws, but also have the ability to hold food in their front claws and still move swiftly on all four feet. They have a slightly reptillian face with fewer feathers, a bald head and a large, powerful beak filled with teeth.

Visus
[Vee-sus]
 Visus' are six inch reptilian birds. They have one pair of wings and two reptilian legs. More like birds they have no scales, but remaining with the reptillian dominance on icarus, these birds posses no feathers. In stead they have  a rubbery-type of skin which secretes an oily substance. This oil is posionous and gives off a putrid smell when they fear something, so creatures who have any thoughts of attacking it think twice. 
Visus' Breed once a year and lay about 5 small ovoid eggs of which about only two or three survive to hatch and one or two make it to adulthood.

 

Racer
[RAY-suhr]
 Large 6-legged reptillians that are cousins of the Draks. They are usually bipedal with a large tail to keep their balance. They come in a wide range of colours that varies from place to place. In stead of wings they have two stubs on their necks that seem to have no functional use. Unlike the draks they posses no consciousness and are used in races and as beasts of burden, pulling carts and obstacles.

Saharel
[Sah- hah-REL]
Small 8-legged lizards that grow from the size of a finger to the size of an arm. Saharels can be trained like dogs to carry messages and fetch items for their owner. Though they are active little creatures they easily get pampered after which they're hard to motivate to say the least.
In the wild, Saharels live mostly in the desert, though they can be found almost every place which has a rocky or sandy ground with enough exposure to the sun. Saharels have in fact been found in forests where they steal eggs of the Visus' nest to eat. 
When they were first seen their hides were mostly tan and brown in colour, though now that they have been carried out around the planet, they come in a rainbow of colours, adapting to their new environments with almost the same ease as chameleons (albeit taking a few generations).
Saharels usually mate up to three times  a year with their mate (if the mate dies, the other half remains alone and will not mate again). If the female is pregnant (which can only happen once a year), she will lay a small clutch of one to four eggs after about 2 months. Guarding the babies in small cracks and openings in warm stone, there is almost nothing that can eat the newborns. Later (about 3 months after they're born), when they emerge from their hiding space they are the most vulnerable to threats.

 

Fludium
[flu-DEE-uhm]
An ocean-dwelling fish about ten feet in length. Fludii are very playful and curious. They swim in pods, much like the Earthen dolphins. They have a tiny, barely visible, dorsal fin, two flippers and one fluke. They are torpedo-shaped which helps give them speed through the water. They are not air breathers, instead, they breath through gills in the water.

 

Cockroach
[KOK-roach]
One of the few species salvaged from the 'Hyantis' after the crash (cockroaches survive anything, right?) they are the only vile of DNA which was never evenbrought up in the discussions about which animals should be ressurected.

Nex Necis (plural Nex Necium):
[nehx NEH - sihs (p. nehx NEH - see - oom)]
Nex Necium are mantid-like creatures have that have eight legs, standing up to 12 feet tall and as long as 18 feet. They walk on their six hind legs and carry their forelegs in front of them. Each leg has two large, deadly, knife-like claws that can kill a human being with one swipe, and can seriously injure even a large Drak. They have scaly, reptilian bodies and can blend in easily with their environment when they want to. The Nex Necium are flexible and can form into tight balls and roll across ground easily or float in water to escape an attack. They are also very intelligent, making them a most-definite match for Draks. Nex Necium have a long, slender tail which ends with a long poisonous spike, much like that of scorpions.
Nex Necium attack villages, castles, or anything else they can get their claws on. They are very nasty creatures and have no mercy for another creature. Nex Necium travel in large packs, making more than a match for helpless villagers, although a single Nex Necis is more than a match for even a group of skilled fighters, and few Draks are willing to challenge a Nex Necis on their own. Usually, the person that is head of the village has a Fairy Drak and can send for help to the castles. But for those on the outskirts of the villages, if they don’t have a Fairy Drak themselves, they will most likely die before any help reaches the village.
On occasion, Nex Necium attack Castles. Their clawed forelimbs are strong enough to breach the hard rock Castle walls, and given enough time they can break into the Castles and swarm inside. Here, they can easily kill the Draks because there is no room to fly. However, most of the time, the Draks and their Knights can stop the Nex Necium before they manage to break into the Castles.

Scale Mites
[Scale Mites]
 Small parasites that live between the scales of the reptiles of Icarus. They burrow under the scales, finding access at the edges of the scales, where the overlap isn't perfect (like where they have been wounded once and never really regrew the scales) and to attack their soft hide. They're very small and annoying to draks, often burrowing into places that the drak can't reach. Humans can develop a salve to repel the bugs, and part of Squire training is how to look for and remove scale mites.

Spider
[SPY-duhr]
Spiders on Icarus are about a foot long and harmless. They have an oval brown body, with red marks on top. Their head has a more greenish sheen with a few large black eyes. They feed on vegetation, not blood like it's terran cousin. They have a preference for sweet-tasting, juicy fruits. 
They are given to children as pets (toys) from the age of 8 and up. Younger children have been known to throw the poor creatures around, creating a messy house and at times, causing the spider to die. 

Venomous Rogue
[VEHN - uh - muhs rowg]
 This creature is not really a plant as its appearance suggests, but a tentacle-bearing animal that mimics vines to allow it to catch it's prey more easily. If another animal wanders too near, the Venomous Rogue reaches out with its tentacles and ensnares the hapless victim. The Venomous Rogue suffocates its prey by tightening its grip, then drags the prey into its tooth-lined mouth, which is concealed in the center of its arms. These creatures favor the more heavily forested tropical and sub-tropical regions but are occasionally found in temperate forests and even taiga regions.
