- •
Harbor porpoises forage nearly continuously day and night to meet energy needs
- •
Porpoises hunt up to 550 small fish prey per hour with a >90% capture success rate
- •
Targeted sizes of fish overlap little with commercial fisheries
- •
Even moderate disturbance may have severe fitness consequences for porpoises
