Large number of whales, orcas in particular, have followed to feed on the herring.
In 2006 orcas and harbour porpoises have also been seen but such sightings are rare.
The average lifespan of a wild female orca is 60 to 80 years.
The decrease has been seen in the populations of: forage fish, salmonids, bottom fish, marine birds, harbor porpoise and orcas.
The parks feature orca, sea lion, and dolphin shows and zoological displays featuring various other marine animals.
Orcas, the largest species of dolphin, have been involved in fatal attacks on humans in captivity.
Orca, cod, dolphins, porpoises, sharks, rockfish, seabird, whales, squid, sea lions, seals, tuna, salmon, and fishermen are among the predators of these fishes.
Once it was completely subdued, the orcas dragged its lower jaw open and gorged themselves on its tongue, then departed without touching the remainder of the carcass.
