A fully grown humpback whale was spotted in California's Sacramento River, roughly 60 miles upstream from the Pacific Ocean. The sighting took place while Denny Glover and his friends were fishing, hoping for a big catch but instead encountering the whale.
Humpback whales are typically ocean-dwelling animals, so this inland appearance is highly unusual. The exact reason for the whale's journey is not yet known, and no other sources provide additional context.
The report offers no details on the whale's condition or whether it has returned to the ocean. It serves as a striking example of marine life appearing in unexpected freshwater environments.
