Skuldrs
Skuldrs are large, mammalian creatures that dwell in caves in total or near-total darkness. As a result, they have poor vision and rely on their sense of hearing to navigate and find prey. The protrusions and hairs on their ears allow them to detect airflow, which is key to telling direction in an underground environment. They communicate through screeches and clicks, and use these vocalizations in a form of echo location. They are communal creatures, choosing to nest and raise young together.
