* Springbok: These are a type of gazelle with distinctive white patches on their flanks.
* Dik-dik: These are very small antelopes, about the size of a rabbit, which can look similar to other small antelope species.
* Gnu: These animals are also bovids, but are more closely related to wildebeest than antelopes. They have a distinctive mane and a hump on their back.
* Saiga antelope: These have a distinctive, large, bulbous nose, which makes them easy to identify.
It's important to note that pronghorn are not true antelopes, even though they are often called "antelope" in North America. They are more closely related to deer.
To differentiate between antelopes and other similar-looking animals, it's helpful to pay attention to their size, shape, horns, and overall appearance.
