Harbor Seals live in coastal areas many of which are heavily fished and this results in entanglement and bycatch issues (see Desportes et al. 2010) Overfishing and environmental variability (including global climate change) may also impact Harbor Seal prey populations.

Harbor seals are brown, silvery white, tan, or gray, with distinctive V-shaped nostrils. An adult can attain a length of 1.85 m (6.1 ft) and a mass of 132 kg (290 lb). Under the seal's skin helps to maintain body temperature.

Females outlive males (30–35 years versus 20–25 years). Harbor seals stick to familiar resting spots or haulout sites, generally rocky areas (although ice, sand, and mud may also be used) where they are protected from adverse weather conditions and predation, near a foraging area. Males may fight over mates under water and on land. Females bear a single pup after a nine-month gestation, which they care for alone. Pups can weigh up to 16 kg (35 lb) and are able to swim and dive within hours of birth. They develop quickly on their mothers' fat-rich milk, and are weaned after four to six weeks. The global population of harbor seals is 350,000–500,000, but subspecies in certain habitats are threatened.

Once a common practice, is now illegal in many nations within the animal's range. Harbor seal swimming Individual harbor seals possess a unique pattern of spots, either dark on a light background or light on a dark. They vary in color from brownish black to tan or grey; underparts are generally lighter.

The body and flippers are short, heads are rounded. Nostrils appear distinctively V-shaped. As with other true seals, there is no (ear flap).

An ear canal may be visible behind the eye. Including the head and flippers, they may reach an adult length of 1.85 meters (6.1 ft) and a weight of 55 to 168 kg (120 to 370 lb). Females are generally smaller than males. Population [ ] There are an estimated 350,000–500,000 harbor seals worldwide.

They may spend several days at sea and travel up to 50 km in search of feeding grounds, and will also swim 100+ miles upstream into fresh water in large.
