In the Old World, they inhabit the Desert, Old Desert, Dunes, Old Jungle, Jungle, Tide Island, Kumbel Wetlands, Primal Forest, and Everwood. They've also been seen in the Deserted Island of the New World.
Daimyo Hermitaur fill a variety of niches. They will feed on just about anything they can get their pincers on. Daimyo Hermitaur will also meticulously sift through large quantities of sand, looking for small creatures and organic material. Daimyo Hermitaur will even eat humans when given the chance. This is a safe way to get a meal, but is a slow process. Daimyo Hermitaurs will occasionally turn to scavenging if food is scarce. These large crustaceans inhabit areas that harbor fearsome predators like Tigrex, Copper Blangonga, Kuarusepusu, Lagiacrus, Plesioth, Abiorugu, Meraginasu, Tigerstripe Zamtrios, and rare Elder Dragons.
They have huge, thick claws capable of holding prey as well as shielding the giant crab from most any attacks. Daimyo Hermitaur's shell is also very tough, able to deflect the blows of most weapons. The one chink in the creature's armor is its soft hindquarters, where many of the creature's major organs are stored. To fix this problem, Daimyo Hermitaur will wear the skulls of dead wyverns on their backs. Acquiring the right size shell is a chore though, and occasionally Daimyo Hermitaur can be spotted with shells too large, or small for their bodies. Almost all of Daimyo Hermitaur's shells come from members of the larger species like Monoblos. Daimyo Hermitaur also possess surprisingly strong legs, able to move the creature with great speed if necessary. The legs assist the creature in digging holes and they are able to launch themselves many feet into the air, causing them to land vigorously on top of hunters who don't react fast enough.
Some unusual rare Daimyo Hermitaur have a dark redish color on their claws, darker legs and more shiny eyes. Along with this their shells are unusually covered in moss or algae. Like Plum Daimyo Hermitaur, they also share the ability to spit long streams of water. They use new attack techniques as their claws are much stronger than average, they use their claws in a shielded position much like a human boxing while walking at a target, these claws are reported to be so strong in this position that ranged projectiles fired from guns ricochet, along with this new smarter advancing technique they perform a very aggressive non stop side to side claw snapping attack behavior that out-speeds most attackers.
Daimyo Hermitaur are rather passive creatures, sometimes failing to take notice of hunters standing only feet in front of them. They are very single-minded and will sometimes become completely focused on the task at hand, which is often feeding. Whenever a Daimyo Hermitaur discovers a new shell that is larger than its old one, it may immediately switch between the two, anticipating its future growth and possible discomfort if it doesn't get a larger shell. Daimyo Hermitaur are not particularly territorial, but may fight one another if local food sources are scarce.
