On September the 11th of 1876, two men by the names of Captain John K. Webster and James Anderson (a surgeon) were on a steamer ship known as the Nestor, when they witnessed a huge, unknown creature undulating through the waters of the Strait of Malacca (located off the coast of Malaysia).  The men watched the creature move around the steamer ship for nearly thirty minutes and documented its appearance before it swam out of sight.
