Seruslong

Physiology
Seruslong are a large brute wyvern that have long tooth filled maws and a long barbed tongue that can be launched out of its mouth to grab smaller prey items, the tails of Seruslong are incredibly long and semi-prehensile and are able to help balance, be used like a whip and constrict large monsters and hunters. Seruslong sports a pair of long, highly developed forelimbs that have powerful four fingered hands equipped with sharp claws. Seruslongs hindlimbs are powerful and robust to carry its massive weight. The hide of Seruslong is strong, flexible and smooth and is able to change its color and texture allowing the beast to hide its massive body from its prey. The creature has no elemental powers or abilities just raw strength and power.

Abilities
Seruslong is able to change the texture of its skin and manipulate the hormones in its body, when it skin takes on a rust color it defense sharply rises and when it skin takes on a red tint it becomes faster and its attacks deal more damage. Seruslong is also able to camouflage itself by blending in with the environment. Seruslongs claws and forelimbs are powerful enough to allow it to dig quickly through solid rock and its rear legs are strong enough to allow it to jump. It can use its barbed tongue to harpoon prey and hunters.

Taxonomy

Habitat Range
Seruslong are native only to the Primeval Coastline and inhabit the large redwood forests located in that region, it is unknown if that is their only range as they are quite reclusive and rare creatures.

Ecological Niche
Seruslong are the top predators in of a lot of areas it is found in. Seruslongs are a keystone species and fill a niche similar to Akantor and its relatives. Seruslong are known to prey on large monsters like Duramboros and even Uragaan and on occasion they will even hunt other large predatory species that wonder into its territory, even the fearsome and powerful Sicarapax, Ferrumos and Dinovaldo are on this monsters menu. The only things that could potentially threaten a Seruslong is other Elder Dragon-Level Monsters or Elder Dragons themselves.

Behavior
Seruslong will attack and kill almost anything on sight, and even when not actively hunting or in combat, Seruslong appear highly aggressive, destroying whatever bothers them as they travel their destinations. These rare monsters have made exploring and documenting the deep forests of the Primeval Coastline an extreme hazard to scientists and guild members.
