Camels and llamas can cross breed.
You may be familiar with cross-species breeding. The most notable example is the mule, a cross between a donkey and a horse. Another prominent example made popular by Napoleon Dynamite is of course the Liger. The Liger, despite what the movie would have you believe, really just looks like a very bulky, very large maneless lion with faded stripes.
Crossbred animals are usually sterile, so they can’t reproduce on their own. New hybrids have to be made from the parents species. A llama and camel, when crossbred, produce what is called a cama. So far, only one has ever been documented.
She was born in 1995. She was humpless and with a long fluffy coat like a llama, but had ears and long, strong legs like a camel. You can see the cama, along with her parents, on the right.
