In some parts of Mobius, the meat of the Umikuji is actually considered a high-priced delicacy; when prepared properly, it is safe to eat, much like how ''fugu'' (the dish prepared from pufferfish) is edible when prepared properly. Also like fugu, Umikuji meat requires specialized chefs to prepare it, and they are required to undergo two to three years worth of extensive training in order to obtain a
licence for this. A single, tiny mistake in the preparation process can have disastrous consequences.
Umikuji are also common victims of the exotic pet trade.
