Nope, it’s not the Orangutan…
Wikipedia says that the blue whale has the largest dong in the animal kingdom. It is commonly cited as having an average dong length of 2.5 metres (8 ft 2 in) to 3 metres (9.8 ft) and a diameter of 30 centimetres (12 in) to 36 centimetres (14 in).
The dong is normally hidden inside the body and jets out through a slit during you-know-what. It’s stated to be tough, and fibrous (more than in any other mammal). It is believed that it uses the elasticity of this tissue to get up, though this hypothesis has not been confirmed by any scientific study. In the book Moby-Dick by Herman Melville, it is mentioned that the size of the outer skin of the whale’s dong is such that it could function as a floor-length protective apron while skinning the dead whale.
