Oyrthirn are reptiles that inhabit all types of environments, each adapted to their specific habitat. They are long, snake-like monsters begin life eating whatever is around them and grow into almost exclusive carnivores.
The young and juvenile have blunted teeth that gradually become jagged due to wear and tear. However, they will lose these teeth around 3 years of age as their sharper adult teeth grow in. These teeth are not constantly replaced and oftentimes one will see an adult Oyrthirn missing a few teeth.
Female Oyrthirn are usually more aggressive than males and dictate which males they mate with. They will lay a clutch of 30 eggs. Depending on the sub-species they may lay their eggs at the base of a tree, in a rock crevice, or a specially dug hole in the ground. Females stay near their nests but will wander away to hunt. Eggs typically hatch after 2 months. The young are left to fend for themselves and many are eaten by larger predators during the first few weeks of life.
Arboreal Oyrthirn often make a large tree that can support their massive frames their home for life. Adults grow to be 300 pounds and 26 feet long. They do not move quickly but are renowned for their camouflage and ambush capabilities. They are also quick to cannibalize on their own species.
The spines, a constant on all species, are mostly vestigial, a remnant from the originally underground-only species, do help somewhat in gripping branches. This particular sub-species have begun to evolve so that their spines lay flat on their bodies, turning into hardened scales that do indeed help them maneuver better.
A false eye is also present on their lower jaws. It is a light colored scale that is used to confuse potential predators (such as certain species of drakes and Grinners) into attacking that spot instead of their actual eyes. This Oyrthirn will lay perfectly still when a predator is nearby and turn it's head upside down to expose the false eye. When a predator approaches, if it attacks the false eye the Oyrthirn will snap it's jaws with astounding speed as it makes an attempt to bite back. This is also one of their hunting methods.
They live in temperate climates (tropical varieties also exist, however, they are exclusively called 'Jungle Oyrthirn' and vary from their temperate climate brethren in color, spine structures, skull structure).
Subterranean Oyrthirn live in tunnels deep within the earth. They are primarily found in caves near mountains inland. They weigh up to 250 pounds and grow to around 15 feet long.
Unlike their tree-faring kin, Sub Oyrthirns are active hunters. There have also been no reported cases of them eating their own kind. The rock-like protrusions on their backs helped them blend in while they move. Due to this they are often mistaken for the landscape and many a traveler has met a grisly end at the teeth of this creature.
They do not have many other natural predators besides a few species of drake.
Oyrthirn have earned the nickname 'Delighted Death' due to how they always appear to be smiling.
There is another creature with a smiling grin named 'Grinner' that also frequents the same forest Arboreal Oyrthirns do. Evolution seems to like smiling predators in it's forests.
Teeth are used to make various tools, medicines, and trinkets. It is not uncommon to find market stalls that specifically sell Oyrthirn tooth products.
Oyrthirn have never been domesticated. There are a few cases of these beasts that have wandered into towns and villages and not attacked, merely slithered through or basked on a roof.
This is one of the most difficult to pronounce things I've ever thought of. I still have trouble saying it.
The original spelling had an apostrophe. I don't remember where. Probably spelled it like Oy'rthirn. Oh wait yeah that was it. I think it helps with remembering where to put the correct stresses on each vowel and consonant in the beginning.
I swear this will be the first thing in the next pronunciation guide audio.
Their teeth are based off of horse teeth/mouths.
