- Family: Lagiacrus
Easily asserting itself as a top predator, this Leviathan preys upon many creatures such as Aptonoth, Epioth, and Jaggi. It also seems to be a scavenger when given the chance. Due to its sheer size, it is able to prey on small to medium sized monsters such as Great Jaggi and Qurupeco without too much trouble. To avoid direct competition with its blue-scaled cousin, it has adapted itself to be more terrestrial. However, this puts it in line with other large predators such as Rathalos, Zinogre, and even Deviljho. Due to its size and electrical capabilities it is able to survive most confrontations with its competitors. If the amount of prey on land runs scarce, however, it still retains the ability to hunt underwater, where it has much more prey to choose from with less competition present. Other aquatic predators such as Plesioth, Royal Ludroth, it's Subspecies, and Gobul will avoid this creature at all costs. Confrontations with their two close relatives are rare, yet do happen on occasion. Ivory Lagiacrus have also been seen feeding on quartz, giving them their unusual color and land-dwelling behavior.
It has the same adaptations as the normal individuals, simply built more for life on land, such as stronger legs and smaller skin pores to reduce dehydration. The reason a Ivory Lagiacrus's shell is a more white color is because its shell is composed mostly of quartz. The shell on their head is composed of more quartz than the rest of its body. But they seem to have stronger electric skills than the normal Lagiacrus. It can use it's shockers at full power without getting any power in them, but if it does put anymore power, it would be completely devastating to any monster that comes across this territorial beast.
Ivory Lagiacrus are quite aggressive compared to their normal species. Ivory Lagiacrus have been seen to attack a lot more different threats compared to the other Lagiacrus and can even hold a grudge against most threats.
