In-Game Information
"海竜 species that live in Sawara. 海竜 lurking in the sand, and attack the hunter in his mouth to mimic the site has a sand castle seems to be weak, exploitable patterns. Sand spit attack, lunge, jump and the bite has been introduced. "

Taxonomy
Confirmed to be a Leviathan. Details on its placing within the group are scarce as of now.

Habitat Range
Endemic to the Sandy Plains.

Ecological Niche
The Hapurubokka feasts on anything that fits in its mouth, much like Gobul does. This can be Rhenoplos, as shown in the intro, but also Delex. It can swim through sand with great speed much like Cephalos, making it a fearsome predator. High on the foodchain, only top predators like the Deviljho, Tigrex, Rathian, Rathalos and Diablos dare to attack it. The Hapurubokka may occasionally attack a Diablos, but this seems unlikely, due to the Wyvern's size and strength. It bears a resemblance to the Asian Hellbender Salamander except with more monstrous features.

Biological Adaptations
It has the remarkable ability to swim in sand, shared only with a few monsters, and its streamlined body helps it move through it at great speeds. It has a huge mouth for eating its prey in one bite, like the Gobul. It has poor eyesight so it locates its prey with hearing. It spits sand at predators that try to eat the Hapurubokka. Its eyes are on top of its head, so it could see its prey easier above when lurking in the sand. The also have salamander-like "gills" probably for helping it spew sand out or to make it easier to breath in the sand.

Behavior
The Hapurubokka hasn't been observed enough to say something about its behavior, but it is probably territorial to smaller creatures, but it would hide itself in the sand when a top predator passes. The Hapurubokka will hide itself in a sand dune when low on health. It may also compete with the Barioth Subspecies for food. Although it may not have a chance of winning territory with other top predators it may become succesful in fighting for food.
