Things You May Not Know About The Nerscylla Subspecies
 * They mainly inhabit the Old Desert/Dunes and can only really be seen wandering it at night.
 * They wear Khezu Skin as a cloak possibly due to a different environment/region. It's unknown how they get the skin and the Guild are researching the Dede Desert so they can find out how along with discovering if Khezu even lives there.
 * One theory fans have is that it leaves the Dede Desert and goes to the Underground Cave/another area in order to kill a Khezu.
 * It should be noted that they have been seen wearing the hide of other monsters as well though unknown which ones.
 * The Nerscylla Subspecies doesn't make a web like the other Nerscylla Species and prefers to wander the desert in search of prey instead of waiting for prey to come to it. When it finds prey, it will sneak up on it by burrowing through the sand and ambush it from underground to catch it off guard and to attack it from its blind spot.
 * It is able to use its web to swing from rocks and cliffs plus it can freely swing in the air with its web like a pendulum.
 * Similar to Nerscylla, it gains its paralyzing toxins from its prey such as Genprey and possibly even the Seltas Subspecies, which is than stored in the spikes on its back. Once its back is broken, the venom will drip from its back. It also still has the poisonous toxins of the other species, which can be injected from its stinger and jaws.
 * From the Nerscylla Subspecies' beautiful colors, it has become a popular good in the markets around the world.
 * The shell has an eerie look to it.
 * The Khezu skin is used to protect itself from its elemental weakness.
