Creating a digital giraffe involved numerous calculations on weight, mass, size, shape, lung capacity and centre of gravity.
Calculations were made to discover rotation dynamics, flotation dynamics and the external surface area of both a giraffe and - for control purposes - a horse.
The authors found that a full-sized adult giraffe would become buoyant in 2.8metres of water. Giraffes can wade across bodies of water that are shallower.

That's a pretty bold statement. Remember, just because it doesn't exist on the Internet, doesn't mean it doesn't exist.
I am not arguing that it's rare, it's just a really big statement saying that no one has ever seen one swim. How many people in Africa live near water and might have seen one take a dip?
