Which animal is primarily raised for its fiber rather than meat?

The animal that is primarily raised for its fiber rather than meat is the alpaca. Alpacas are domesticated members of the camelid family, and they are valued primarily for their soft and luxurious fleece, which is used to produce various textiles. The fibers from alpacas come in a range of natural colors and have qualities that make them desirable for garments and other products.

While other animals may also provide fiber or have other uses, such as moose and buffalo, they are not primarily raised for fiber production. Moose and buffalo are generally raised for their meat and other animal products. Fish, though raised in aquaculture, are not relevant in the context of fiber at all. Thus, the alpaca stands out as the correct choice for an animal raised primarily for fiber.
