A conservation lens
Deep-sea animals often grow slowly, and recovery can be difficult after habitat disturbance or heavy fishing.
This habitat lens is not a current population-status assessment. Status can differ among regions and change as new assessments are published; follow the reference links and local fisheries or wildlife agencies for current decisions.
