An incredibly rare and critically endangered North Atlantic right whale was recently sighted off the coast of Massachusetts, accompanied by her calf in a heartwarming display of nature's resilience. This marks the first sighting of the season and has sparked excitement among researchers and conservationists alike.
The mother whale, identified as Legato (EgNo 1802), is a 36-year-old descendant of Staccato (EgNo 1014). Her calf, born in December, was first spotted on New Year’s Eve in Florida. The sighting off Cape Cod Bay on April 1st was a moment of joy for the team from the Center for Coastal Studies, who were conducting aerial surveys in the area.

Ryan Schosberg, part of the observing team, shared the thrill of spotting the duo. "We were just finishing a survey track line when we saw a right whale feeding less than a mile from the beach off North Marshfield. We flew over to document the animal and all cheered in excitement when a little calf popped up by its side!"
The migration of North Atlantic right whales from their calving grounds in the southeast U.S. to the feeding grounds in New England and Canada is a perilous journey. Cape Cod Bay serves as a crucial stopover where the whales find calm waters and abundant food after surviving challenging conditions.
Dr. Charles “Stormy” Mayo, director of the Center’s Right Whale Ecology Program, emphasized the significance of Cape Cod Bay for these endangered creatures. "It must be a relief, no wonder they hang out here for days or weeks," Mayo remarked.
The presence of Legato and her calf is not only a testament to their successful migration but also a reminder of the species' critical status. With only about 360 North Atlantic right whales estimated to be left, every birth is a beacon of hope. The Commonwealth of Massachusetts has taken steps to protect these whales by limiting boat speeds during right whale season to prevent ship strikes, one of the greatest threats they face.
The sighting of Legato and her calf brings optimism and highlights the importance of conservation efforts to ensure the survival of these majestic creatures for generations to come.
The North Atlantic right whale (Eubalaena glacialis) is a majestic marine mammal known for its colossal size, distinctive appearance, and critically endangered status. Here are some detailed insights into this fascinating species:
-
Physical Characteristics:
-
Size: North Atlantic right whales are among the largest whales, with adults reaching lengths of up to 50 to 60 feet (15 to 18 meters) and weighing as much as 70 tons.
-
Appearance: They have a robust body with a stocky build and a large, broad tail. Their heads are massive, making up about one-fourth of their total body length. One of their most distinguishing features is the presence of callosities, which are rough patches of raised skin covered in white crustaceans, on their heads. These callosities are unique to each whale and are used by researchers for individual identification.
-
Coloration: Their bodies are mostly black, with occasional white patches on their bellies.
-
-
Habitat and Range:
-
North Atlantic right whales inhabit the North Atlantic Ocean, ranging from the southeastern United States in winter to the Gulf of St. Lawrence and occasionally further north in summer. They are known to migrate seasonally between their feeding and calving grounds.
-
Feeding Grounds: These whales primarily feed on zooplankton, especially copepods, by filter-feeding through baleen plates in their mouths. They are often found in areas with high concentrations of plankton, such as Cape Cod Bay and the Bay of Fundy.
-
-
Behavior and Reproduction:
-
Social Behavior: North Atlantic right whales are typically seen alone or in small groups. They are known for their slow, deliberate movements while feeding near the surface.
-
Reproduction: Females reach sexual maturity at around 10 years of age and give birth to a single calf every 3 to 5 years after a gestation period of about a year. The calves are born in warmer waters and are nursed by their mothers for several months before they are weaned.
-
-
Conservation Status and Threats:
-
Critically Endangered: The North Atlantic right whale is one of the most endangered large whale species globally, with only an estimated 360 individuals remaining. It has faced centuries of intense whaling that drastically reduced its population.
-
Threats: The species continues to face numerous threats, including entanglement in fishing gear (such as lobster and crab pot lines) and ship strikes. These human-induced factors pose significant risks to their survival and reproductive success.
-
-
Conservation Efforts:
-
Conservationists and researchers are actively involved in efforts to protect North Atlantic right whales. These efforts include:
-
Implementing regulations to reduce ship speeds in areas frequented by whales to minimize the risk of collisions.
-
Developing and promoting whale-safe fishing gear to prevent entanglements.
-
Conducting research and monitoring programs to study their behavior, population trends, and health status.
-
-
Understanding and conserving the North Atlantic right whale is crucial not only for the species' survival but also for maintaining the health and balance of marine ecosystems they inhabit. Efforts to protect these magnificent creatures are integral to preserving biodiversity and ensuring a sustainable future for our oceans.
