The total harbour seal population in the eastern north Pacific is estimated to be 330,000, and in California the estimated population was 40,000 in 1997. They usually are found in small groups, but sometimes occur in numbers of up to 500.
RANGE/HABITAT: Harbour seals are found across the Northern Hemisphere in both the Atlantic and Pacific Oceans. In the Northeast Pacific, they range from Alaska to Baja California, in Mexico. They favor near-shore coastal waters and frequent sandy beaches, mudflats, bays, and estuaries.
Harbour seals spend about half their time on land and half in water, and they sometimes sleep in water. They can dive to 1,500 feet (457 m) for up to 40 minutes, although their average dive lasts 3 to 7 minutes. They are opportunistic feeders and hunt for sole, flounder, sculpin, hake, cod, herring, octopus, and squid.They will also take fairly large salmon.

At Race Rocks,the Harbour seals are year round residents, although their numbers peak in mid summer to over 400. They have pups on the island from March to July. This file shows what happens if boat traffic is too fast in the ecological reserve or around any seal haulout area,
