'''Things you may not know about the Espinas, Espinas Subspecies, Espinas Rare Species, and the Meraginasu(Info comes from Famitsu, 4gamer, mhf-wiki.net, atwiki.jp, wikiwiki.jp, and mhfo.wikiwiki.jp)

Espinas

Firstly, Espinas is strong enough fight against Elder Dragons and its said it was engaged battle with one in a battle over territory. It in the end was able to scare of the Elder Dragon(Its unknown what kind of Elder Dragon Espinas fought but most fans believe its either Kushala Daora or Chameleos).

Espinas isn't truly a threat to people from it pretty much almost always being clam.

The reason why Espinas doesn't go into Rage Mode instantly is because from their armor they will just wait afew minutes and hope for the threat to give up and, move on. If the threat doesn't give, you guys can already guess what happens.

Once its enraged, it will try to eliminate/kill the threat as a last resort. While enraged, blood flow increase and blood vessels dilate and, this can be seen on some parts of the Espinas' body.

Poison is in all of its spines.

The toxic balls it spits out have two different poisons combined together. One that can paralysis prey, another that can cause prey to bleed out(I'm really just thinking about two different venoms usually used by snakes).

Espinas are well-known for having all sorts of scars on their body from previous attacks or battles.

Its scales are much harder than any other known Flying Wyvern's scale.

The toxins used by all three Espinas are different from each other and it seems that the Espinas Subspecies has the strongest toxins because its toxins are said to cause plants to wither. For older individuals, their toxins are said to be enough to kill people with ease.

Its tail spikes are said to constantly produce poisons and that its used as an offensive weapon. The tail spikes of the other two are different but far deadlier.

The Espinas Subspecies combines its poison with a heavy amount of acids that decrease a hunter's defense.

The Espinas Subspecies habitats are different from the Espinas, which its only known to be found in the Gorge and the Towers. The Espinas Subspecies is adapted for harsher environments.

Older(HC) Espinas Subspecies are well-known for being aggressive, even when their not enraged.

Shortly after discovering the Hypnocatrice Rare Species, there were sightings of large fires in the area. This later on led to the discovery of the Espinas Rare Species, when the Guild investigated this.

The Espinas Rare Species ecology is still a mystery at this point.

The Espinas Rare Species seems to be the most aggressive Espinas since as soon as its awakened by any threat, it will instantly go into Rage Mode.

Meraginasu

These mighty wyverns live in the deepest parts of the Tide Island Caves and they have come from ancient times.

Meraginasu was once thought to be an extinct species but not until it was recently rediscovered living underground in the Tide Island Caves.

Meraginasu might also help the Guild discover Espinas' ancestor.

It seems to be specialized for living underground and in caves where sight isn't needed.

This monster isn't an Espinas, its a close relative of Espinas.

It can't see very well but it has very good hearing. It also is constantly on the prowl for prey, searching for it and hunters.

It will raise its ears up high to listen to anything that is in the area but will fold them when its not using them.

Some things are suggesting that this thing maybe a predator to one of our cave dwellers, which I'm guessing Taikun Zamuza.

Meraginasu uses an unknown element that hasn't been seen before. It seems to be Thunder + Water(In this cause body fluids)though it hasn't been confirmed yet.
