Grey whale is also known as a grey back whale, California Grey Whale, or Pacific Grey Whale. It is a baleen whale. It migrates during feeding and breeding periods every year. The average and typical lifespan of gray whales is still unknown, but once a female grey whale was estimated around the age of 75 to 80 years after death. It has a long sleek torpedo-shaped body which is perfect for diving and swimming with less drag effort and with greater speed.

Its skin excretes tiny oil droplets due to which drag effort is decreased even more. The outer layer of the whale’s skin sheds rapidly and again helps to reduce the drag effort. The average size of a blue whale is about 49 feet long and is pretty heavy and weighs around 90,000 pounds which is like 30 to 40 tons. Female grey whales are slightly larger in size as compared to male whales. They are found in shallow coastal waters of the Northern Pacific Ocean, during migration sometimes crossing the shores of deep waters. They are omnivores.
