Alpacas are similar to an animal called a llama and usually people mistake the two.
I like alpacas a lot!  They're from Peru and Bolivia.  Their wool makes great blankets.
Alpacas similar closely and can successfully cross breed.
I wonder if a cross-bred llama and alpaca have a different name?  Like a donkey does?
Yes great blankets I agree. There are two types of alpacas and one is known as the Huacaya Alpaca.
One bad thing about captive alpacas is that they can spit on you.  I've read that it's a behavior they use to keep aggressors away, or to protect their food.  I've never been spit on by one, but I've come close!
Yes I heard they are spitters. There fibers can be used for woven and knitted items like wool.
