Akantor Ecology

Disclaimer:: This is merely a plausible explanation for the monster(s) in this article, and should not be considered canon.

Taxonomy
Due to its large size and appearance, many claim that it is an Elder Dragon. This however is false, it is a Pseudowyvern, like the Tigrex. It has similar tail, forearm, and upper skull structure to that of a Tigrex. Albeit a very large Pseudowyvern. Akantor is an ancient creature and represents what is perhaps the pinnacle of psuedowyvern evolution.

Habitat Range
It is evident that Akantor's bodily functions thrive in areas exibiting a very high temperature, making the Volcanic Belt a suitable home. Stated that it will roam freely be is confined to the volcanic belt by a good portion of the Hunters Guild's collective might. Most likely will deplete an area's large prey (and predator) population before moving on to a another region.

Ecological Niche
Akantor is a top predator; nothing else appears large or powerful enough to prey on it. Is so poweful it can have extremely negative effects on the environment it resides in. Predator and prey flee from Akantor and only the largest wyverns even dare challenge it.

Biological Adaptations
Akantor's dark black shell is perfectly suited to the volcanic belt. It can burrow into the lava and stay there for a short period of time due to having thick plating. The large spikes on it's back help deter any airborn attacks. Akantors famous tusks are equally effective at burrowing into dense lava as they are gutting and killing a large wyvern.

Behavior
Akantor is highly aggresive and predatory - it is shown to be more than capable of taking down a Gravios. It will attack and kill almost anything on sight, often letting out a defening roar before charging head on.
