Arkenors could be considered either forest or water creatures because they live in wet, woodland areas. They can see as well at night as they can in daylight. Have spines on their backs and muscular fore legs ending in sharp claws which they use to grab and kill their victims. They have the webbed fingers which make them good swimmers. They live in small groups consisting of only a few individuals. They prefer dark places like caves and do their hunting at night. During the day they are very difficult to see, but some are found on occasion.
