Note — In addition to sightings on Monterey Bay Whale Watch trips, this list includes all reported marine mammal sightings for this region. Sightings marked * were reported by other boats in the Monterey Bay area, including fishing, research, private and whale watch boats, as we keep track of all sightings in the Bay through our sighting network. Unusual sightings of other marine animals such as Leatherback Sea Turtles and Basking Sharks are also listed. California Sea Lions, Harbor Seals, and Southern Sea Otters, which are seen on all whale watching trips, are not included in the list.
