Common Name: North Atlantic Right Whale
Scientific Name: Eubalaena glacialis
Length as an adult: 52 ft (16 m)
Weight as an adult: 77 tons (69 kg)
Length and Weight at birth: 12ft (3.5 m) 1 ton (0.9 kg)
Length of Pregnancy: 12 months
Range: East coast of North America from Newfoundland to Florida; a population that existed off Iceland and northern Europe is now thought extinct
Likelihood of being seen on a whale watch in Massachusetts coastal waters: It’s very rare to see them but it’s more often to see them early spring
Preferred Food: zooplankton, especially copepods
Unusual Characteristics: They have raised, hardened patches of skin known as callosities. Each callosity pattern is unique to the individual animal.
Appearance: A large, mostly black whale with whitish patches on the head and belly, no dorsal fin, and a graceful, deeply notched "fluke," or has long, mustache-like fringes of baleen instead of teeth, which it uses to strain tiny animals from the water for food. Two blowholes on the top of its head give a distinctive v-shape to a right whale’s spout.
General Information: One of the most endangered marine mammals in the world. Once lived up to 50 to 70 years old, but whales born today have a life expectancy of approximately 15 years.
Unusual Habits: Right whales gather in ‘surface active groups’, large congregations of whales that interact very closely with one another.
Population Status: 500 individual right whales
Threats: Entanglement in fixed fish gear, ship collisions, climate and ecosystem change, and disturbance from whale watching boats
