A conservation lens

Coastal development, vessel pressure, degraded water quality, and seagrass loss can shrink feeding and nursery areas.

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.
