North Atlantic Right Whale | ![]() |
| (Eubalaena glacialis) |
Physical Statistics:
Right whales can reach 60 feet in length. They tend to be rather rotund in nature, weighing up to 80 tons.Field Marks: Due to the nature of the blowholes, which are further apart than other baleen species, a right whales blow is v-shaped if seen from behind and is very low and bushy. While on the surface, the most noticeable feature is the large, broad back and lack of a dorsal fin. The flippers are rather large, dark and paddle-shaped. When diving, the right whale will bring its large, dark tail out of the water and will occasionally stay down for over 20 minutes at a time. With the exception of spring, right whales are usually seen in this area traveling alone or in pairs. Right whales are the most endangered cetacean in the North Atlantic.
Individual Identification: Along the head, each right whale has a number of light-colored growths called "callosities" that form around the blowholes, snout, eyes and lower jaw. Callosities are calcified skin patches that form a pattern on the head unique to each individual. The pattern changes little and has allowed researchers to identify 374 individuals, although 49 of these are presumed dead. Scarring on the body is another way of identifying individuals. Unfortunately, over 60% of the population have scars due to entanglements or ship strikes.
