BLUE WHALE, Balaenoptera musculus (Linnaeus) . Cosmopolitan; occurs along both the 

 Atlantic and Pacific coasts of North America. Numbers greatly reduced through 

 excessive exploitation; protected by international agreement since 1966. Status 

 a matter of special concern because of decimation of numbers prior to protection 

 and apparent scarcity of the species at the present time . 



FINBACK WHALE, Balaenoptera phy sal us (Linnaeus). Cosmopolitan; occurs along both 

 the Atlantic and Pacific coasts of North America. Still widely hunted; not pro- 

 tected by international agreement . Considered in peril because of uncertainty of 

 the effects of continued exploitation, and lack of international protection. 



SEI WHALE, Balaenoptera borealis Lesson. Cosmopolitan; occurs off both the Atlantic 

 and Pacific coasts of North America . Still widely hunted; not protected by 

 international agreement. Considered jeopardized because of the effects of wide- 

 spread exploitation , and the lack of adequate protection . 



HUMPBACK WHALE, Megaptera novaeangliae (Borowski) . Cosmopolitan; occurs along 

 both the Atlantic and Pacific coasts of North America . Numbers greatly reduced 

 because of excessive exploitation prior to protection; protected, since 1966', by 

 international agreement. Considered in need of special attention due to greatly 

 reduced population. 



RIGHT WHALE, Eubalaena glacialis (Muller) . Polar, temperate and tropical seas; in 



North America roughly from Iceland to Bermuda in the western Atlantic, and from 

 Alaska to Baja California in the eastern Pacific . Population may now be stable; 

 protected by international agreement. Considered in need of attention because 

 of greatly reduced numbers . 



BOWHEAD WHALE, Balaena mysticetus (Linnaeus) . Northern oceans, south to the 

 Pribilof Islands and the Gulf of St. Lawrence. Greatly depleted in numbers; 

 protected by international agreement and population may now be stable . Con- 

 sidered as in need of careful watching because of its low population level .
