Answer:
The animal with the longest tail also has a pretty long neck. The male giraffe has a longer tail than the female. The male's tail can grow up to an incredible eight feet in length! The female giraffe's tail is not quite as long.
Archaeologists discovered that prior to the giraffe, the animal with the longest tail was a dinosaur called the Diplodocus. From a dig to recover this huge animal in 1878, they found from the skeleton that the Diplodocus' tail was almost three times as long as its body!
