One treatise from 1963 on the delightfully esoteric topic of ‘the swimming capacity of the golden hamster‘, states “it is well known that most wild mammals can swim”; most, but not all. From the literature, a consensus emerges that there are two groups of mammalian non-swimmers: giraffes and great apes.
Giraffes definitely don’t look like natural swimmers. With such extreme anatomy, it seems plausible that they really are unable to float in water. No one has ever been foolhardy enough to build a giraffe-sized water tank, but thanks to a couple of inquisitive palaeontologists they might not have to.
Intrigued by numerous mentions in the literature, science writer and palaeontologist Darren Naish decided to test the hypothesis that giraffes can’t swim. “I’m extremely sceptical of such claims, given that other animals sometimes said to be unable to swim – like giant tortoises, pigs, rhinos and camels – actually swim just fine or even very well,” he wrote in his Tetrapod Zoology blog.
To devise an experiment that was both ethical and dry, Naish approached Donald Henderson of the Royal Tyrrell Museum of Palaeontology in Drumheller, Alberta, Canada. Henderson specialises in creating computer models of animals both extinct and extant. “I originally started making these models for locomotion and estimating body weight, but then I realised I could also look at flotation,” he explains. As luck would have it, Henderson actually had a giraffe model pre-prepared, so the pair decided to finally put the matter to bed by finding out whether or not it would float.
“We found that the giraffe could float and its head was close to the surface, but it would have a bit of a struggle to keep its nostrils clear,” says Henderson, explaining that drag on the creature’s long limbs would also make it pretty ungainly in the water. “It’s not impossible that a giraffe could swim, but it would be strenuous, and I could see why they would be reluctant to do it,” he concludes. “That may give rise to this observation that giraffes don’t swim.”
