Protozoa are a very diverse group of single-celled organisms, with more than 50,000 different types represented. The vast majority are microscopic, many measuring less than 1/200 mm, but some, such as the freshwater Spirostomun, may reach 0.17 in (3 mm) in length, large enough to enable it to be seen with the naked eye.
Although the best know type of Spanish wine is red wine, Spain also produces very high quality white wines, especially in Galicia. Jerez (sherry) is another type of Spanish wine which is produced in the south, near Jerez in Andalusia.ndoubtedly, the better known region is La Rioja, especially for its red wine, but there are many other Spanish wine regions that produce high quality wines, like Ribera del Duero in the north of Spain, or Jumilla in the south of Spain.
Sherry is produced in a variety of styles made primarily from the Palomino grape, ranging from light versions similar to white table wines, such as Manzanilla and Fino, to darker and heavier versions that have been allowed to oxidise as they age in barrel, such as Amontillado and Oloroso.
