Nuzzling the shoreline with the curiosity and daring that made its ancestors easy prey for whalers, a young right whale is swimming slowly northward along the East Coast toward Martha’s Vineyard. The 20-ton mammal is keeping odd company with a giant sea turtle, and together the silent mammoths have been snooping lazily around Long Island for about two weeks.

One of the rarest creatures on the earth, the endangered right whale, was seen near the Vineyard Tuesday. The sighting off the Gay Head Cliffs is for the record books, a first for the Vineyard in a long time.

The Northeast Right Whale is one of the world’s most endangered marine mammals, with only slightly more than 300 known to be in existence. One was observed from an airplane while it was feeding.

“Cap’n” Seth Wakeman Jr. of Menemsha reports that representatives of the Oceanographic Institution at Woods Hole got “some of the best whale pictures ever taken,” during a recent visit to the Island. In addition to taking still and movie shots, the scientists also had excellent luck in recording the sounds of the whales which have been seen off Menemsha Bight and Gay Head in recent weeks.
