The yearly gray whale migration is one of Earth’s most fantastic nature shows. Everyone who came to Mission Bay had a whale of a tale to tell. At about 10 a.m., a gray whale was seen along the Mission Bay entry channel off Mission Point Park, south of Mariner’s Point. Those who had gathered on the coast anticipating seeing the whale were captivated by it. The fascinating gray whale may grow to be between 40 and 50 feet long and more than 36 tons (72,000 pounds) in weight! Gray whales, as their name implies, have white spots on their dark gray bodies. The white spots represent scars, color variations, barnacles, and even whale lice. The whale’s weight may be increased by up to 400 pounds by the latter two.
What Time of Day Are Gray Whales Most Active?
Gray whales are often active at night, but have been seen to be more active at other times of the day, seasons, and activities. Gray whales are less active at night during the summer, since their prey is easier to find during the day.
Although they can be crepuscular, gray whales are never nocturnal. Thus, they are most active in the twilight period, which includes the time just before and right after sunset. During these twilight hours, the whales may converse with one another without being heard by predators or prey, since the water will absorb their voices. In the twilight hours, seeing predators or prey is also simpler since there’s still enough light to see, but it’s dark enough to notice shadows. Since whales’ primary food supply, plankton, needs sunshine to develop, they are more likely to be active during the day. During the summer months, when plankton is more abundant, whales are less active at night.
