Habitat

Harbor seals inhabit coastal waters, estuaries, and beaches in the Northern Hemisphere, from temperate to subarctic regions. They prefer areas with easy access to haul-out sites like rocks, sandbars, or ice floes for resting and breeding. These seals are adaptable and can be found in both protected bays and open ocean shores.

Diet

Harbor seals primarily eat fish such as herring, anchovies, and flounder, which they catch by diving to depths of up to 500 meters. They also consume invertebrates like octopus, squid, and crustaceans, often feeding at dawn and dusk when prey is more active. Their feeding behavior involves stealthy pursuits in shallow waters near the coast.

Behavior

Harbor seals are generally solitary or form small groups when hauled out on land, but they can gather in larger numbers at prime resting sites. They are diurnal, spending much of the day resting on shores and foraging in water, with males showing territorial behavior during the breeding season. These seals are curious and may approach boats, but they are agile swimmers capable of evading threats in the water.

Conservation Status

The IUCN status of harbor seals is Least Concern, with populations stable or increasing in many areas due to protective measures. Major threats include habitat degradation from pollution, entanglement in fishing gear, and disturbance from human activities.
