The animal seen in July 1984 was entrapped in a codtrap and resisted all attempts by humans to come near it. At times it was very aggressive toward approaching boats. Eventually the animal towed the codtrap with all its supporting grapnels out to sea. Despite extensive searching the animal was not seen again, and it is believed that it could not have survived. Discussion The only sighting program in this study where results can be quantified was the one operated by MUN. For this program, sighting rate of Right Whales by land-based observers was 0.0009 per person-week of observation. This compares with 0.02 for Killer Whales {Orcinus orca); 0.34 for Humpbacks (Megaptera novaeangliae); 0.22 for Minke Whales {Balaenoptera acutorostrata); and 0.32 for Long-finned Pilot Whales {Globicephala.

Although Right Whales occasionally occur in waters off Newfoundland and Labrador, they are indeed very rare. During the decade (1978-1987), there were three additional sightings of Right Whales that have been reported. Sears (1980) saw th
