Snakes in the genus Bitis have a similarly impressive display. The hognose snake flattens its neck and raises its head so that it looks like a cobra, all the while hissing in a way that sounds like it’s puffing air in and out. Some people call the various species of hognose snake found in North America puff adders too because of its behavior when it feels threatened. It also has a pair of nose horns but they’re smaller and generally point up and slightly back.Īll snakes in the genus Bitis have a threat display that has earned them the name puff adder, although that’s also the name of a specific species, Bitis arietans, that’s extremely venomous. It’s sort of a more sophisticated-looking rhino viper. It looks similar to the other rhino viper with a similar pattern but in more neutral tones of brown and tan. rhinoceros is also called the West African Gaboon viper because it lives in West Africa.
Rhinoceros also means nose-horn, by the way. Sometimes the rhino viper is called the butterfly viper because of its colorful markings, and to stop people from confusing it with another closely related snake called Bitis rhinoceros. This is the closest thing to a hand that snakes have. The end of its blunt tail is even partially prehensile, meaning it can curl around branches to help it hang on. The rhino viper spends most of its time on the ground, but it can climb trees if it wants to. It has relatively mild venom, although some other Bitis species have venom that’s deadly to humans. Most of the time it moves slowly, but when it strikes, it does so very quickly, in less than a quarter of a second. It’s an ambush hunter, meaning it hides among fallen leaves and waits for an animal to come too close. The rhino viper mostly eats rodents but will also eat frogs, birds, and other small animals if it can catch them. Some rhino vipers even have three nose horns. It has a pair of horns, in fact, side by side, and they stick up and slightly forward. Nasicornis means nose horn, and it definitely has horns on its nose. Actually it’s pronounced “bit-is.” It’s spelled B-I-T-I-S. At first I thought it was pronounced like “bite us,” which I thought was hilarious, and I was disappointed to find that it’s pronounced “bit-us,” although that’s actually funny too. The rhino viper’s scientific name is Bitis nasicornis. It’s not a good idea to pet wild snakes anyway. The rhino viper’s scales are so strongly keeled that they can cut your hand if you pet it. It has rough scales that make it look bristly, called keeled scales.
If you look at one on a white background it stands out, but on the forest floor where it lives, with dead leaves and plants all around, it blends right in.
It’s a heavy chonk of a snake but it’s beautifully colored, with big triangular blotches and smaller markings of red, yellow, black, and blue or green. The rhinoceros viper lives in forests in parts of western and central Africa, and can grow three and a half feet long, or 107 cm. This week we’ll learn about the rhino viper, which was suggested by Max, who at the time was almost eight years old but that was so long ago I bet Max is eight now or maybe nine or ten. Just a reminder about our Kickstarter for the Strange Animals Podcast book!
