Einode Winterschlaf-Halten (Ger. desert hibernate, umlaut over the "o")

(Homo piscis pulmo)

These are another species of rare wesen. Einode Winterschlaf-Halten are lungfish-like wesen. They are harmless, yet quite strong and capable of taking care of themselves. They are very persistent and are not bothered by people telling them that they won't succeed. These wesen are capable of going into a state of suspended animation, for a prolonged period of time, in a cocoon known as a "Trocknen Stabbeutel" (Ger. dry sac). This state is known as "Wuste Schlaf" (Ger. desert sleep) and it is not known if there is a limit to the time an Einode Winterschlaf-Halten can spend in Wuste Schlaf. The Trocknen Stabbeutel is produced through glands on either side of the mouth. This phenomenon is becoming rarer, but is was originally done to avoid predators, basically "hibernating" until the enemie forgot about them. Unlike other fish wesen, they don't dehydrate, in fact, they are exceptional at conserving water.

When woged, the body becomes covered in extremely tough scales. The nose vanishes and the mouth shrinks. A long fin developes along the back.
