Deep-sea sharks often have some of the longest lifespans among fish.

Sixgill sharks grow slowly and mature late compared to many coastal species, a life-history strategy suited to stable deep environments. However, slow reproduction limits rapid population recovery after fishing pressure.

Removing mature individuals eliminates decades of growth investment. Populations cannot rebound quickly when reproductive turnover is low.

A giant that withstood asteroid-scale extinctions can still decline under modern exploitation. Longevity that once ensured survival now increases vulnerability in human-dominated oceans.
