There are two types of Alpacas - Huacaya and Suri. Huacaya is the predominant species constituting 90% of the Alpaca population.
Suri is more rare breed featuring long, glossy and silky coat, compared to Huacaya's fluffy teddy-bear like coat. Because of its silky quality and rare supply, Suri fetches higher price in international markets.
