North Atlantic right whales are not so lucky. Although protected since 1970, they number only 450. Ship strikes are a major cause of mortality since they inhabit the North Atlantic in busy sea lanes. Federal officials have proposed a critical habitat zone of 39,655 miles along the East Coast to save them from extinction. Southern right whales are experiencing a die-off. Over the past decade 400 whale calves have died for unexplained reasons. Researchers are tagging southern right whales in order to follow their movements in the vast South Atlantic more closely. Hopefully the satellite telemetry will help explain the increased calf mortality rate. Southern rights are still the most abundant of the three species of right whale, rebounding at 7% a year from the end of commercial whaling.
