Do hippopotamus have horns?

“Do hippopotamus have horns?”

 

Occasionally I like to check the keywords used on search engines that lead to our blog. This task of mine has lead me to realise that this is something that many people ask but we hadn’t covered it.

In order to answer the question “Do hippopotamus have horns?” we must first answer the following question:

 

“What is the difference between hippopotamus and rhinoceros?”

 

So why would I assume that the problem here is that you might be confusing hippos and rhinos?
The answer is quite simple. In terms of appearance, habitat and even (some) behaviour, both species can be quite similar, therefore many people sometimes get them mixed up.

So first of all let’s check out the similarities between species:

 

Both Rhinoceros and Hippopotamus are:

  • Big, heavy animals (both males and females weighing over a tonne),
  • Greyish in colour with a thick skin,
  • Mammals (babies drink milk from the mother),
  • Located in the African continent,
  • Very dangerous to humans,
  • Herbivorous (only eat plant matter),
  • Territorial (males),
  • Faster than any human on Earth (yes, even Usain Bolt),
  • Can’t swim.

Now what about the differences between these two species?

Rhinoceros:

  • Second largest land mammal,
  • There are 5 different species of rhinos: white rhinoceros (Ceratotherium simum), black rhinoceros (Diceros bicornis), javan rhinoceros (Rhinoceros sondaicus), indian rhinoceros (Rhinoceros unicornis) and the sumatran rhinoceros (Dicerorhinus sumatrensis).
  • Located in Africa and Asia,
  • Spend their day on land,
  • Have been around for about 11 million to 15 million years,
  • Don’t have any sharp teeth,
  • Are odd toed ungulates (with three toes on each foot).
  • Very threatened by illegal poaching,
  • Are one of the Big 5 species,
  • Have horn(s). The Javan and Indian species have only one horn while the black, white and sumatran species have two horns on their face.

Hippopotamus:

  • They are the third largest land mammal,
  • There are only 2 species of hippopotamus: the “normal” hippopotamus (Hippopotamus amphibius) and the pygmy hippopotamus (Choeropsis liberiensis),
  • Only located in Africa,
  • Spend most of their day inside the water (but can’t swim!),
  • Share a common ancestor with whales,
  • Have been around for 8 million to 16 million years,
  • Have very big, sharp canines and incisors (tusks), used for fighting,
  • Are even toed ungulates (with four toes on each foot),
  • Not as threatened by illegal poaching as the rhino,
  • Don’t have horns!

So to conclude:

Hippopotamus do not have horns but they do have big tusks that they use to defend against predators or fight each other.

Rhinoceros use their horns to defend against predators and fight each other since they don’t have tusks.
