What is the primary function of the critical den established by the territorial wolf eel?

Answer

Resting, avoiding predators, and potentially raising young

The den is arguably the most critical element of the wolf eel’s habitat requirement, as these solitary and territorial fish depend entirely on it for survival and reproduction. This safe haven, usually a deep, narrow crevice within rocky reefs, serves multiple vital functions. It acts as a secure location for the eel to rest throughout periods when they are not foraging. Crucially, it provides defense against larger predators. Moreover, the stability and protection offered by the den are necessary for the potentially delicate process of raising their young, making the establishment and defense of this single spot paramount to their life cycle.
