Spanish Fighting Bull

These are special bulls.

They live on large farms. They have very long horns. They are strong and fast.

Some bulls are black. Others are dark brown. They have big muscles on their necks. This helps them use their horns.

These bulls do not see the color red. They move when they see things moving. This is how they react to the capes.

Sometimes, a bull is very brave. If a bull is brave, people may let it live. It can go back to the fields.

These bulls live on very large farms. They are bred to be strong and fast. They also have a lot of energy. Most are black or dark brown. They have large muscles on their necks. We call this a morrillo. This helps them use their long horns.

Many people think red makes these bulls angry. This is not true. The bulls have dichromatic vision. This means they are red-green colorblind. They actually react to the movement of the cape.

When a bull shows great courage, it can be pardoned. This is called an indultado. The crowd uses white cloths to ask for this. If the leader agrees, he shows an orange cloth. The bull then goes back to the fields. He can live for 20 to 25 years.

The Spanish Fighting Bull is a special kind of cattle.

These animals are bred for specific traits. They are chosen for their strength and stamina. They also show a lot of energy and aggression. Most of these bulls live on huge, open estates. They roam free in places like the dehesas of Spain.

This way of life helps them keep their natural ways.

These bulls have a very athletic look. They have a large muscle group over their neck and shoulders. This is called a morrillo. This muscle helps them use their long horns with great strength. Mature bulls can weigh between 400 and 700 kg.

Many people think the color red makes them angry. This is actually a mistake. Bulls have dichromatic vision, which means they are red-green colorblind. They react to the movement of the cape instead of the color.

Raising these bulls follows a careful path. Calves spend their first year with their mothers. After they are weaned, they live in groups of the same sex. When they reach two years old, they undergo testing called the tienta. For males, this tests their aggression toward horses. It also shows how they use their horns.

If a bull is very brave, he might be indultado. This means he is pardoned and his life is spared. The crowd asks for this using white handkerchiefs. If the leader agrees, he shows an orange handkerchief.

History shows these bulls have very old roots. Some people think they come from wild bulls in the Iberian Peninsula. Genetic studies show they have a very old genetic pool. In May 2010, scientists achieved something new with them. They cloned a bull named Vasito for the first time. The new calf was named Got, which means "glass" in Valencian.

This calf was carried by a surrogate cow.

Some specific lines of bulls are very famous. The Miura line is known for being large and fierce. These bulls come from a ranch in the province of Seville. One Miura bull first appeared in Madrid on 30 April 1849. These bulls have a reputation for being very cunning. Some people even say they can learn quickly in the arena. This makes them very different from other types of cattle you might know.

The Spanish Fighting Bull is a specific population of Iberian heterogeneous cattle known as *Bos taurus*.

These animals are not raised like typical livestock for meat. Instead, they are bred exclusively on extensive, free-range estates. These estates are often located in countries where bullfighting is a traditional organized activity. Breeders select these bulls for a precise combination of traits. They look for high levels of aggression, energy, strength, and stamina. To keep these natural instincts sharp, bulls rarely encounter humans during their development. When they do meet people, they are never encountered on foot.

Physically, the fighting bull has a very distinct and athletic appearance. They are not bred to be heavy like meat-producing cattle. Instead, they possess a prominent morrillo. This is a complex of muscles located over the shoulder and neck. This muscle structure gives the bull its powerful profile and allows it to use its horns with great force. Their horns are longer than those found in most other cattle breeds. Both males and females possess these horns. While many are black or dark brown, other colors are also normal. Mature bulls typically weigh between 400 and 700 kg.

A common misconception involves how these bulls perceive color. Many believe the color red makes them angry during a fight. However, cattle have dichromatic vision, which means they are red-green colorblind. They do not react to the color red itself. Instead, they respond to the movement of the muleta, which is the cape used by the bullfighter. The red color is used for tradition. It is also believed to help conceal blood stains and provide a sharp light-dark contrast against the arena floor.

The lifecycle of a fighting bull follows a very strict sequence. Calves spend their first year of life with their mothers. After they are weaned, they are branded and placed into single-sex groups. When they reach approximately two years of age, they undergo a testing process called the tienta. For males, this test determines if they are suitable for breeding, bullfighting, or meat. In the bullfight test, they are checked for aggression toward horses. Regulations prevent them from charging humans on the ground during this stage. They also use their horns to test strength and dominance against other bulls.

There are specific legal requirements for bulls entering the ring. At three years old, males are called novillos and are ready for training fights. To fight in a first-rank bullring, a bull must be at least four years old. He must also weigh at least 460 kg. Second-rank rings require a weight of 435 kg, while third-rank rings require 410 kg. Additionally, the bull must have fully functional vision and even, untampered horns. Sometimes, a bull is indultado, or pardoned, for outstanding behavior. If the audience petitions with white handkerchiefs and the president shows an orange handkerchief, the bull's life is spared.

An indultado bull can live for 20 to 25 years.

The history of this breed is deeply rooted in the Iberian Peninsula. Some commentators suggest they descended from wild bulls used in Roman Empire arena games. While the exact origins are disputed, genetic studies show they have an unusually old genetic pool. This breed became popular in Spain, Portugal, and parts of Latin America. It also spread to Southern France during the 19th century. In May 2010, scientists achieved a major milestone by cloning the breed. They cloned a bull named Vasito to create a calf named Got. The name Got means "glass" in Valencian.

Within the breed, there are several distinct subtypes called encastes. There are "foundational breeds" like Vistahermosa, Vázquez, Gallardo, and Cabrera. Today, only the bloodlines of Vistahermosa, Gallardo, and Cabrera remain. The ranch known as Ganadería Miura is famous for its influence from the Cabrera line. Miura bulls are known for being large, fierce, and cunning. They have a reputation for being individualists with strong personal characters. Some observers, including writer Ernest Hemingway, noted their ability to learn quickly during a fight.

This makes them a very complex and respected part of biological and cultural history.
