Sleen: There are several varieties of this six-legged, long bodied carnivorous mammal. It is almost like a snake. Some can get as big as twenty feet long and up to twelve to fourteen hundred pounds. They have two rows of teeth in a wide and triangular head. Their paws have six claws. They smell like a weasel or ferret but only stronger. Sleens are very dirty animals. It is an efficient, tireless, almost infallible hunter. It is capable of pursuing a scent, days old, for hundreds of pasangs. Sleens in the wild are burrowing and nocturnal. They do not climb. Their preferred prey is the tabuk.

They mate once a year in the spring. Their mating ritual is interesting. If a female has never mated before, she will flee and fight a male sleen. The male must finally take her by the throat and, belly to belly, mate with her. After mating once, a female never needs to be forced again. The mating season is usually confined to the spring. Their gestation period is six months and there are usually four young born. The young are commonly white furred and darken by the next spring. Young sleen are about eight feet long and adults are nineteen to twenty feet long. A young sleen's attack is noisy, a whistling rush, a clumsy squealing charge. An adult sleen sometimes makes kills swiftly and silently. There is also a hunting frenzy underwent by some sleen that is a function in part of the secretions of certain glands.

Most domestic sleen are bred as it is hard to tame a wild one and a wild sleen could revert. If young sleen are taken from their mother within the first two months of their life, there is a good chance they can be tamed. It may still revert though, especially in the spring, during the mating period. The specific verbal signals between a master and his trained sleen are private. Verbality is important as a sleen on the hunt may not look at his master. Sleen are used for herding verr and bosk, tracking tabuk and slaves, guarding and patrolling, and many other activities. In Thentis, sleen sniff out the smuggling of black wine beans. Assassins even sometimes use them. The Gray sleen is the best tracker. The forest sleen is large, and commonly either brown or black. Prairie sleen are smaller than forest sleen, usually only seven feet in length. They are domesticated as herd sleen and used as shepherds and sentries by the Wagon People. Aquatic sleen, or sea sleens, are common in the north. There are four varieties of sea sleen in the north including the black sleen, brown sleen, tusked sleen, and flat-nosed sleen. Many migrate though some remain largely dormant in the winter. Their principal prey are parsits and they follow their migrations. A medium-sized adult sea sleen is about eight feet long and weighs 300 to 400 pounds. There is a white snow sleen in the north as well. Sleen hunters, for luck when they kill one, eat its heart. The heart of the mountain larl brings the most luck. There are no sleen in the rainforests. The sleen is considered Gor's most perfect hunter.

Tabuk: There are several varieties of this one horned, yellow antelope. The common type frequents Ka-la-na thickets. It is small, graceful and eats berries and salt. Young tabuk rarely leave the thickets. Their hide is a mottled yellow and brown. Northern tabuk are massive, tawny, and swift. Many stand ten hands at the shoulder. Northern tabuk hairs are hollow and give its fur an excellent insulative quality. Both types have a single horn of ivory, a deadly weapon. It is a yard or so long and two and a half inches at the base. The herd of Tancred is a gigantic herd of northern tabuk, one of several. This herd winters in the rims of the northern forests, south and east of Torvaldsland. In the springtime, short-haired and hungry, they migrate northward, following the shore of Thassa until they reach the tundra of the polar basin for their summer grazing. When winter comes, long-haired and fat, they return south. The prairie tabuk reside in the Barrens. They are tawny, single-horned, and travel in herds. Some varieties lie down when sensing danger. They can attain short-term speeds of eighty to ninety pasangs an Ahn. Their evasive leaps can cover thirty to forty feet in length and heights of ten to fifteen feet. There are twenty varieties of tabuk in the rainforests.

Tarsk: This is a six-tusked wild boar, with a bristly mane running down its spine. There is a giant tarsk that stands ten hands at the shoulder. There are several varieties of tarks in the rainforests, both large and small. They can be domesticated and the rencers keep some. They are best hunted from the back of kaiila with lances and the giant tarsk is often hunted on tarnback with lances. Tarsk meat tends to be salty.

                                                                     
REPTILES

Hith: This is the huge, many banded python of Gor. The great banded, horned hith is the most feared constrictor but is only native to certain areas of the Great Forests. The golden hith is a rare snake. Its body would be difficult for a grown man to encircle with his arms.

Mamba: This is a large, predatory river tharlarion from the rainforests. It has a long, log-like body with short powerful legs. It has a long snout and tail. It is similar to a crocodile.

Ost: This is a venomous, brilliantly orange snake that is little more than a foot long. Its bite causes an excruciating death within seconds. A powder prepared from its venom can be put into wine. The osts of the rainforests are red with black stripes. The banded ost is yellowish orange and marked with black rings. .

Salamanders: In the salt mines, salamanders are tiny, white and blind. They are long bodied with long, stemlike legs. They have fernlike filaments at the sides of their heads that are feather gills, an external gill system. They have a slow metabolism and are capable of long periods of dormancy

Tharlarion: There are numerous varieties of this reptile. One type is a species of saddle lizard, common on Gor especially in swamplands and deserts. They are used mostly by those who have not mastered tarns. Tharlarions have been bred for a thousand generations before the first tarn was tamed. Wild tharlarion have round, shining eyes, webbed feet, teeth ridges and a long brown tongue that curls around their prey. They are carnivorous creatures. High tharlarion are short-tempered creatures, that run on its two back feet. Its forelegs are tiny and near useless. They respond to voice signals though sometimes the butt of a lance is needed to move them, hitting them about the eye or ear openings. Those are the few sensitive areas on its body as they are almost impervious to pain, having a sluggish nervous system. Most of the larger varieties have a brain and a smaller brainlike organ, located near the base of the spine. They need far less water than tarns and their metabolism is slower than a tarn. When they move slowly, their stride is a proud, stalking movement. When going fast, they bound in leaps that can carry them twenty paces at a time. Its saddle is built to absorb shock, unlike the tarn saddle. Mounted warriors though still wear a leather belt around their waists. They also wear high, soft boots to protect against the abrasive hide of the creature. Draft tharlarion are four footed, slow moving animals. They are herbivorous and also known as Broad tharlarions. There are at least four species of draft tharlarion.
Sea tharlarion, immune to the poison of Cosian wingfish, grow up to thirty feet and more in length and have a yellowish slatted belly. Rock tharlarion are the small lizards of the Tahari. There are tiny water tharlarion, about six inches long, that are little more than teeth and tail like piranha. Some live in the swamps. There are also marsh tharlarion and river tharlarion. River tharlarion are long necked, web-footed, and scaled. Some of them are herbivorous and can be domesticated. They may be used to tow barges on the Cartius River. Tharlarion are also used as cavalry and there are even racing tharlarions. Racing tharlarion are usually larger and more agile than saddle tharlarion but smaller than draft or war ones. The city of Venna is famed for its tharlarion races. Some select breeds of racing tharlarion include the Venetzia, Torarii and Thalonian
