Harbor Seal

Communication

Vocal Communication

  1. Harbor seals are probably the least vocal of all pinnipeds.
  2. In air, they may snort, hiss, growl, or sneeze - often as a threat to another seal. Harbor seals vocalize mainly underwater.
  3. Pups vocalize more frequently than adults, especially with their mothers. Pups' sheep-like cries are individually distinctive to their mothers.
  4. Mature males vocalize underwater as part of a display during the breeding season.

Visual Communication

  1. A harbor seal may slap the water or its own body with a pectoral flipper to show aggression, or during courtship.
