The meat listed with chicken as a main ingredient of paella is rabbit. In the Wikipedia infobox, the meat-based description names chicken and rabbit alongside seafood, vegetables, beans, and saffron.
Rabbit is especially important in paella valenciana, the traditional Valencian version often regarded as the original recipe. Its usual ingredients include Valencian rice, olive oil, chicken, rabbit, green beans, lima beans, tomato, saffron or a substitute, salt, and water. Duck and snails may also appear in regional or seasonal versions.
Seafood paella is a separate variation that replaces land meat with shellfish or other seafood. Mixed paella combines meat and seafood, but many Valencians consider that style less traditional. Pork, beef, and lamb may appear in adaptations outside Valencia, yet they are not the paired meat named in the standard paella infobox. Chorizo is another frequent international addition that remains controversial in discussions of authenticity.
