What very fine long silky wool comes from these animals?

Please give me the names of the animals! I need to know which animals you're referring to in order to tell you what kind of wool they produce.

For example, you could say:

* "Very fine long silky wool comes from these animals: sheep"

* "Very fine long silky wool comes from these animals: goats"

Once you tell me the animals, I can tell you about the wool they produce.
