I made Grayhound of the Sea stands for Fin Whale from Maurice Burton's Animal World In Color: Animal Explorers and Wanderers, I found picture book of Fin Whale, there's words is The Large "Grayhound", but however, Grayhound of the Sea is a nickname for Fin Whale, but Fin Whale is second largest Laurasiatheroglires on Earth but after Blue Whale is larger. Maurice Burton (28 March 1898 – 9 September 1992), he's a zoology and studies author animal books.

THE LARGE "GRAYHOUND"/GRAYHOUND OF THE SEA

The Fin Whale (Balaenoptera physalus [synonyms: Piscovenator physalus/Crustaceovenator physalus) also known as Finback Whale, Razorback Whale, Common Rorqual Whale, Finner Whale, Herring Whale, or Grayhound Whale (sometimes called it 'Greyhound' Whale), found in all the oceans of the world, is called the Grayhound of the Ocean, because of it's slender build and great speed in swimming. With an average length of seventy-five feet, and a maximum of eighty-two feet, it is indeed a large 'grayhound' but one with extraordinary driving power and strength: and it can be bad-tempered, particularly - and understandably - when wounded by a harpoon. At such times a finner has been known to throw all its weight, force, and speed into blind fury, sometimes attacking the whaling ship from which the harpoon has been fired. In 1910, a woodenbarked whaler, the Sorenson, was charged in this way by a finner travelling attwenty-five knots. The ship was ripped apart and sunk. A mumber of similar incidents have have been recorded in the pasty sixty years. Another whale, firmly harpooned towed a whaling ship with it's engines going full speed astern at twelve knots before eventually - after a long thrashing fight - tiring itself out. These 'grayhounds' are distributed over the seven seas but they are not common in polar sea. They may migrate from Greenland to Japan and from Chile to Alaska, and when on these long curises they travel in large groups, travelling straight ahead and at a speed that axes the whalers to overhaul them.
