Barboach are small, loach-like Pokémon that are covered in a slimy film at all times. They have an innate sense of seismic activity that is better developed in their evolved form, Whiscash. Barboach have blue whiskers that work as a superb radar in even the murkiest of water, as well as rounded pectoral fins and a tail fin. Judging by this, it is suggested that they aren't fast swimmers, but are hardy fish Pokémon. The main body of a Barboach is a soft grey colour with a jagged black line running the length of their body—this might represent a fissure crack or fault line, reflecting Barboach's dual types—Ground and Water.
