The Iberian Wolf is a gray wolf subspecies native to the Iberian Peninsula, with a current population of around 2,000 wolves, 300 of which live in Portugal. Smaller than other gray wolf subspecies, Iberian wolves have large triangular ears, slanted yellow eyes, and fur ranging from brown to black mixed with gray. They live in hierarchical groups of 3 to 10 wolves led by an alpha pair and prey primarily on wild boar, deer, and occasionally domestic animals. Hunting and loss of habitat drastically reduced the wolf's historic range across the Iberian Peninsula by the 20th century.
