Espinas Rare Species Ecology

In-Game Information
(Due to the lack of a UK release, information on the White Espinas is not currently available.)

Taxonomy
Flying Wyvern. The White Espinas is a subspecies of the Espinas Flying Wyvern. Either that, or the White Espinas possesses either an albinism or leucism, that drains its cells of any pigment and leads to the white coloration.

Habitat Range
Unlike its cousins, the Espinas and Orange Espinas, the White Espinas is particular to the Sea of Trees, where it is among the apex predators of the food web. If the theory concerning its albinism/leucism is correct, then it is entirely plausible that the shade offered by the thick canopy protects it from sunlight; something that would lead to long term damage.

Ecological Niche
In direct competition for sustenance with the Azure Hypnocatrice, the White Espinas relies on its thick hide for protection against would be attackers. It is not fiercely territorial, remaining entirely passive unless angered. There are very few nerve endings underneath the thick, incredibly tough hide -- however, when enraged, vasodilation pushes the skin outwards, forcing them to the surface and softening the hide slightly. This increased blood flow also allows it to move at much greater speeds.

In its chest, the Espinas holds several toxin sacs that it mixes with the fire sacs in its body to both burn and poison any aggressor that it enrages. With prey, the sheer strength of its charge combined with the sharp spines on its body are enough to take its food down.

Behaviour
A largely passive creature, the White Espinas fights back only when enraged. When it does so, it is a very destructive wyvern, throwing its fiery poison breath attacks in every which way. It is known to destroy its habitat in order to kill the creature -- or Hunter -- that has angered it, so extreme caution is recommended when tackling this ferocious Flying Wyvern.
