Harbor Porpoise

About

How harbor porpoise lives

Harbor porpoises are small toothed whales that hunt fish in cool coastal waters. Their low triangular dorsal fin often appears briefly before they vanish underwater. Coastal species are often adapted to tides, wind exposure, and rapidly changing shorelines.

Conservation

Status and habitat pressure

Vulnerable species face mounting risks and can decline quickly if habitats continue to shrink. Protecting harbor porpoise also depends on keeping coast, ocean habitats healthy and connected.

Vulnerable species can decline quickly when habitat loss, climate pressure, or human conflict intensifies.
