There are approximately 20,000 gray whales during the winter and spring migrations. A group of 200-400 whales feed along the Oregon coast during fall and summer. From March through June most of gray whales make the journey from their breeding lagoons in Baja California to the Arctic feeding grounds.Subsequently, one may also ask, do GREY whales travel in pods?
A: Most northbound gray whales travel in pods of two whales. We sometimes see larger pods; very occasionally we see pod sizes of over 10 gray whales. The moms with calves rarely travel in large pods; cow/calf pairs are usually solitary, but sometimes join together during periods of peak migration.
Similarly, what route do GREY whales travel during their migration? Gray whales have the longest known migration of any mammal. They travel 10,000-12,000 miles round trip every year between their winter calving lagoons in the warm waters of Mexico and their summer feeding grounds in the cold Arctic seas.
In this manner, do male gray whales migrate?
It takes about 5 - 10 years for gray whales to become sexually mature but most members make this 11, 000 to 12,000 mile (round trip) migration each year. The gray whale reaches full size after about 40 years with males about 42 feet long and females about 49 feet long.
Why do gray whales migrate along the coast?
Gray whales migrate 10,000 miles round trip every year, traveling between their winter calving lagoons in Mexico and summer feeding grounds in the Arctic. When seen off the California coast, they aren't stopping to eat or socialize, they're on their equivalent of a road trip, not even stopping to sleep.
What do gray whales do at night?
Scientists have also documented gray whales (Eschrictius robustus) sleeping with one eye open.

During summer, they live in the Arctic in areas rich in their food, bottom-dwelling organisms. As fall approaches, there is less sunlight, less food, and the water turns cold. This is when the whales travel to Baja California, Mexico where they enter lagoons to give birth and mate.Are gray whales aggressive?
Gray whales earned the nickname “devil fish” because of their aggressive reactions when harpooned. Gray whales are known for their curiosity toward boats and are the focus of whale watching and ecotourism along the west coast of North America.What time of year do gray whales migrate?
From March through June most of gray whales make the journey from their breeding lagoons in Baja California to the Arctic feeding grounds.What is the gray whales diet?
Gray whales mostly eat shrimp-like amphipods, but also eat surface-dwelling swarms of krill and small, schooling fish. A Pacific gray whale feeds by swimming slowly over the muddy bottom, at depths down to 200 feet.Is the gray whale extinct?
