Things you may not know about the Lagiacrus Species(Info comes from MH3U, wikwiki.jp, mh3neko, trinfo, and other fc2 blogs)

Firstly, all three Lagiacrus species are the same species, Ivory most likely being a mutation while Abyssal is an old Lagiacrus, note that both the normal and Ivory Lagiacrus turn into the Abyssal after a long time(I already know alot people are pissed off now but, like HellWolf said "Its Capcom Logic").

Their breeding habits are unknown but, in ways the normal Lagiacrus in Low Rank could be considered a juvenile, much like the immature Rathians in Low Rank, though its unconfirmed that the Low Rank Lagiacrus are just juveniles.

Lagiacrus live for quite a long time and it takes them a very long time to turn into the Abyssal Lagiacrus. They also continue growing for their whole life much like some reptiles.

Ivory Lagiacrus are rarely seen and their populations are quite small compared to the normal Lagiacrus.

Ivory Lagiacrus' electrical abilitys surpass the normal Lagiacrus' electrical abilitys and even Zinogre's electrical abilitys.

Unlike the normal Lagiacrus, the Ivory Lagiacrus doesn't need to cool down after discharging lightning from its body and can repeat it as many times as it wants.

It seems Ivory may eat quarts for extra defense against other monsters.

It seems the Ivory Lagiacrus in the village urgent was soon going to become an Abyssal Lagiacrus. The same also goes for the "Cruel King of the Sea" Ivory Lagiacrus.

It seems out after a set amount of time and, when they reach a certain size or age, either a normal or Ivory Lagiacrus will disappear in the sea mysteriously and never be seen again. After disappearing in the sea, they begin their process of turning into the Abyssal Lagiacrus.

The Abyssal Lagiacrus is a recently discovered form of the Lagiacrus species and wasn't known until the events of MH3U. There is also no official records on this thing from its rarity but, it is suppose to be the largest Leviathan and possibly the 1st Leviathan ever discovered(I'm to not sure about the second one).

The Abyssal Lagiacrus can remain permanently charged as long as it is alive.

The Abyssal Lagiacrus glows to attract plankton to feed on.

Its electrical abilitys far surpasses the other two and even rivals some Elder Dragons and other powerful electrical monsters.

The Abyssal uses its whirlpools to drag prey into the abyss and to drown them before feeding on them.

Its unknown why their color changes as an Abyssal Lagiacrus.

Lastly(This is unconfirmed), the Abyssal Lagiacrus may possibly use "Dark Thunder" like Doragyurosu.
