Right whales reach sexual maturity within 7-10 years and a cow is capable of producing only one calf every third or fourth year. The gestation period lasts for about one year and they will suckle their young for the equivalent length of time. It is assumed that they can live for nearly seventy years. Pilot whales are sometimes seen on Stellwagen Bank during the fall and winter months. They can reach lengths of up to 25 feet and weigh up to 4,000 pounds.
Pilot whales tend to remain in the cool temperate waters of the North Atlantic.
They may occasionally cross paths with their closest relative, the short finned pilot whale, in the vicinity of Virginia. Their principle diet consists of squid and fish. Sexual maturity will generally occur between 6-12 years and the females are capable of producing one calf every third year. The cows will continue to feed their young for almost two years before weaning them. Studies conclude that they may live for nearly 70 years.
