Harbor seals may weigh between 180 and 285 lbs (80-130 kg). Fish, octopus, and squid make up the bulk of their diet. Though normally associated with the ocean, harbor seals will happily follow spawning eulachon and salmon up rivers and sometimes into lakes or ponds. Their coats come in a variety of colors, varying from dark to light.
Harbor seals were traditionally hunted by the Tlingit people: a practice that continues today with both fur and meat being used. Although native peoples are allowed to hunt seals, they and other marine mammals are strictly protected. Orcas will also feast upon harbor seals.
