Harbor Seal

Brief Description

A medium-sized marine mammal often seen resting on rocks or beaches in coastal areas.

Characteristics

Spotted coat ranging from silver-gray to brown/black, lack of external ear flaps, short flippers with claws, and a distinctive 'V' shaped nostril pattern.

Habitat

Coastal waters, sandy beaches, rocky shores, and estuaries.

When to Find It

Visible year-round, but often haul out on land during low tide to rest and regulate temperature.

Conservation Status

Least Concern (IUCN), though protected by the Marine Mammal Protection Act in several countries.

Ecological Role

They are apex predators in many nearshore ecosystems, helping to regulate fish and invertebrate populations.

Easily Confused With

Sea lions (which have external ear flaps and can rotate their hind flippers forward to 'walk') and Grey Seals (which have a longer 'horse-like' snout/profile).

Observation Tips

Keep a distance of at least 150-300 feet to avoid disturbance; seals haul out to rest and can become stressed or abandon pups if approached.

Interesting Facts

Harbor seals can dive to depths of over 1,500 feet and stay underwater for up to 30 minutes, though most dives are shallow and short.
